Offline Software

Embedding

Welcome to the STAR Embedding Pages!

Embedding data are generally used in STAR experiments for detector acceptance & reconstruction efficiency study. In general, the efficiency depends on running conditions, particle types, particle kinematics, and offline software versions. In principle, each physics analysis will need to formulate its own embedding requests by providing all the above relevant information. In STAR Collaboration, the embedding team is assigned to process those embedding requests and provide these embedding data, you can find out how the embedding team works in the Embedding structure page.

Over the past years, lots of embedding requests from different PWG's have been processed by the embedding team, please find the list in STAR Simulations Requests interface. If you want to look at some of these data, but do not know where these data are stored, please go to this page. If you can not find similar embedding request, you need to formulate your own embedding request for your particular study, please go to this page for more information about how to formulate an embedding request.

Please subscribe to the embedding mailing list if you are interested with embedding discussion: Starembd-l@lists.bnl.gov
And please join our weekly embedding meeting : https://drupal.star.bnl.gov/STAR/node/65992

Finding existing embedding data

Embedding data were produced for each embedding request in the STAR Simulations Request page.
Normally, they will be stored in RCF NFS disks for a while for end users to do their analysis.
However, NFS disk space is very limited, and we have new requests constantly, the data will be finally moved
from disks to HPSS for permanent storage on tape, but they can be restaged to disk for analysis later.

In order to find the existing embedding either on disks or in HPSS. Please follow the procedures below:

1) Find the request ID of a particular request that you are interested in, in the STAR Simulations Request page.
    You can use the "Search" box at the top right of this page. Once you find the entry, look at the 'Request History' tab for more information, usually the original NFS data directory (when the data was first produced) can be found there.

2) Currently, the RCF NFS disks for embedding data are /star/data105, /star/embed and /star/data18.
    For the data directories of each request, please logon to RCF, look at '/star/data105', '/star/embed' or '/star/data18' to see whether the following directories exist:

/star/data105/embedding/${Trigger set name}/${Embeded Particle}_${fSet}_${RequestID}/
/star/embed/embedding/${Trigger set name}/${Embeded Particle}_${fSet}_${RequestID}/
/star/data18/embedding/${Trigger set name}/${Embeded Particle}_${fSet}_${RequestID}/

3) If they exist, you can further check whether all the ${fSet} from 'fSet min' to 'fSet max' are there. If all exist, 
    you can start to use it. If none of them are there or only some fraction of 'fSet' are there, write to the embedding list
    and ask the Emebedding Coordinator to restage it to there from HPSS.

4) If you can not find the embedding data in this directory, the data must be in HPSS. Unfortunately, there is not a full list of data stored in HPSS yet. (For some data produced at RCF, Lidia maintains the list of embedding samples produced at RCF.) Please write to the embedding list, provide the request ID, Particle Name, file type (minimc.root, MuDst.root or event/geant.root), and ask the Embedding Coordinator to restage the data to NFS disk for you.


Operations (OBSOLETE)

The full list of STAR embedding requests (Since August, 2010):
http://drupal.star.bnl.gov/STAR/starsimrequest
The operation status of each request can be viewed in its page and history.

The information below (and in sub-pages) are only valid to OLD STAR embedding requests.

Request status

- Currently pending requests

- Old Requests summary (circa Nov 2006)

New requests

 

 

Current Requests

Current Requests were either submitted using the cgi web interface before it had to be removed (September 2007) or via email to the embedding-hn hypernews list.

As such there is not a single source of information. The excel spreadsheet here is a summary of the known requests as of August 2008 (also pdf printout for those without access to excel). The co-ordinator should keep this updated.

Heavy flavour have also kept an up to date page with their extensive list of requests. See here.

[The spreadsheet was part of a presentation (ppt|pdf) in August 2008 on the state of embedding at the end of my tenure as EC - Lee Barnby]

New Requests

In the near future we hope to have a dedicated drupal module available for entering embedding (and simulation) requests. This will have fields for all the required information and a work flow which will indicate the progress of the request. At the time of writing (August 2008) this is not available. A workable interim solution is to make requests using this page by selecting the 'Add Child Page' link. One should then write a page with the information for the request. Follow-up by members of the embedding team and requestors canthen use the 'Comment' facility on that page.

The following is required

  • pt range
  • pt distribution (flat, exponential)
  • rapidity
  • ...
  • (to be completed)

Submit a new embedding request

Before submitting a new request, a double-check in the simulation request page is recommended, to see whether there are existing requests/data can be used. If not exist, one need to submit a new request. Please first read the 'Appendix A' in the embedding structure page for the rules to follow.
If the details of the embedding request has been thoroughly discussed within the PWG and hence approved by the PWG conveners. Please the PWG convener add a new request in the simulation request page and input all of the details there.

There are some key information that must be provided for each embedding request. (If you can not find some of the following items in the form, simply input it in the 'Simulation request description' box.)

Detailed information of the real data sample (to be embedded into).

  • Trigger sets name. for example, "AuAu_200_production_mid_2014", a full list of STAR real data trigger sets can be found in the data summary page.
  • file type. for example, "st_physics", "st_ht", "st_hlt", "st_mtd", "st_ssdmb". Please note that ONLY those "st_*_adc" files can be used for embedding production. Due to limitation of disk space, we usually sample 100K events (~200-500 daq files, depending on trigger and other event cuts), and this set of daq files will be embedded multiple times to reach the desired full statistics (say 1M).
  • Production tag. for example, "P15ic"
  • Run range with list of bad runs, or a list of good runs. for example, "15076101-15167014"
  • trigger IDs of the events to be embedded. for example, HT1 "450201, 450211"

  • vertex cut, and vertex selection method. for example, "|Vertex_z|<30cm", "Vr<2cm", "vertex is constrained by VPD vertex, |Vz-Vz_{VPD}|<3cm", "PicoVtxMode:PicoVtxVpdOrDefault, TpcVpdVzDiffCut:6" or "default highest ranked TPC vertex".

  • Other possible event cuts, for example, cut on refmult or grefmult, "refmult>250"
  • Each request can only have ONE type of dataset described above.

Details for simulation and reconstruction.

  • Particle type and decay mode (for unstable particle). for example, "Jpsi to di-muon"
  • pT range of input particle and the distribution. for example, "0-20GeV/c, flat", or "0-20GeV/c exponential"
  • pseudo rapidity or rapidity range (the distribution is flat), for example, "pseudo-rapidity eta, -1 to 1", or "rapidity, y, -1 to 1". Please do make clear it is "PSEUDO" rapidly or rapidity, as they are quite different quantities.
  • Number of MC particles per event. Usually "5% of refmult or grefmult" is recommended, one can also assign a fixed number, for example "5 particle per event" for pp collisions.
  • For event generator embedding request, like Pythia/HIJING/StarLight in zero-bias events, please provide the generator version at least. For example, "Pythia 8.1.62". The PWG embedding helper or PA's are fully responsible to tune-up the parameters for the generator in such embedding requests.
  • One can add special requirement for production chain in 'BFC tags' box, for example turn off IFT tracking in Sti.
  • Please indicate whether EMC or BTOF simulator is needed.

Finally, please think carefully about the number of events! The computing resources (i.e. the CPU cores and storage) are limited ! 


It is acceptable to modify the details of the request afterwards, although it will be of great help if all above detailed information can be provided when a new request is submitted, in order to avoid the time waste in communications. If this is inevitable, please notify the Embedding Coordinator immediately if the details of a request is modified, especially when the request is opened.

bfcMixer.C Reshape

b>Date: Wednesday, 18 April 2007
Time: 12:21:45
Topic: Embedding Reshape

18 April 2007 12:21:56

Talked to Yuri on Monday (16th)

He would like 3 things worked on.

1. Integration of MC generation part into bfcMixer.C

Basically all kumac commands can be done in macro using gstar.

These would become part of "chain one"

Also need to read in a tag or MuDst file to find vertex to use for generating particles.

Can probably see how this works from bfc.C itself as bfc.C(1) creates particles and runs them through reconstruction.

- actually I could not it is inside bfc.C or StBFChain because it is part of St_geant_Maker

2. Change Hit Mover so that it does not move hits derived from MC info (based on ID truth %age)

3. [I forgot what 3 was!]

Rough sketch of chain modifications for #1

Current bfcMixer

                Geant-?-SetGeantMaker<--tags file

Break down into sub-tasks.

a) Run bfcMixer.C on a daq file with an associated fz and data file (to check that it works!)

b) Ignore fz file and generate MC particle (any!) on the fly

c) reading from tags file generate MC particles at desired vertex & with desired mult.

d) tidy up specify parameter interface (p distn, geant ID etc.)

Embedding Procedures

Overview



This document lists the procedures used for requesting embedding, running embedding jobs, and retrieving data. Please note that some steps require privileged accounts.


Embedding Documentation

Overview


The purpose of embedding is to provide physicists with a known; Monte Carlo tracks, where the kinematics and particle type is known exactly, are introduced into the realistic environment seen in the analysis - a real data event. How reconstruction preforms on these "standard candle" tracks provides a baseline which can be used to correct for acceptance and effciency effects in various analyses.

In STAR, embedding is achieved with a set of software tools - Monte Carlo simulation software, as well as the tools for real data event reconstruction - accessed through a suite of scripts. These documents attempt to provide an introduction to the scripts and their use, but the STAR collaborator is referred to the separate web pages maintained for Simulations and Reconstruction for deeper questions of the processes involved in those respective tasks.

Please note, the general procedure for embedding is:
  • The Physics Working Group Convenor submits an embedding request. The request will be assigned a request number and priority by the Analysis Coordinator, see this page for more information.
  • The Embedding Coordinator will coordinate the distribution of embedding requests. Users who wish to run their own embedding are encouraged to do so - but it must be verified with the Embedding Coordinator.
  • The Embedding Coordinator is responsible for the QA of all embedding requests. When the Embedding Coordinator has verified that the test sample produced is acceptable, full production is authorized.


Obsolete documentations

Embedding Production Setup

This page describes how to set up embedding production. This procedure needs to be followed for any set of daq files/production version that requires embedding. Since this typically involves hacking the reconstruction chain, it is not advised that the typical STAR PA attempt this step. Please coordinate with a local embedding coordinator, and the overal Embedding coordinator (Olga).
Note: The documentation here is very terse; it will be enriched as the documentation as a whole is iterated on. Patience is appreciated.

Get daq files from RCF.

Grab a set of daq files from RCF which cover the lifetime of the run, the luminosity range experienced, and the conditions for the production.

Rerun standard production but without corrections.

bfc.C macros are located under ~starofl/bfc. Edit the submit.[Production] script to point to the daq files loaded (as above).

Put tags files on disk.

The results of the previous jobs will be .tags.root files located on HPSS. Retrieve the files, set a pointer for the tags files in the Production-specific directory under ~starofl/embedding.


Now you're ready to start production.

Embedding Setup Off-site

Introduction

The purpose of this document is to describe step-by-step the setting up of embedding infrastructure on a remote site i.e. not at it's current home which is PDSF. It is based on the experience of setting up embedding at Birmingham's NP cluster (Bham). I will try to maintain a distinction between steps which are necessary in general and those which were specific to porting things to Bham. It should also be a useful guide for those wanting to run embedding at PDSF and needing to copy the relevant files into a suitable directory structure.

Pre-requisites

Before trying to set up embedding on a remote site you should have:
  • a working local installation of the STAR library in which you are interested (or be satisified with your AFS-based library performance).
  • a working mirror of the star database (or be satisfied with your connection to the BNL hosted db).
If these two things are working correctly you will be able to process a daq file with the usual bfc.C macro. Check that you can do this and do not proceed further if this is not the case as you will be wasting your time. You can find the correct bfc.C options to use with a particular daq file and software release combination here.

Collect scripts

The scripts are currently housed at PDSF in the 'starofl' account area. At the time of writing (and the time at which I set up embedding in Bham) they are not archived in CVS. The suggested way to collect them is to copy them into a directory in your own PDSF home account then tar and export it for installation on your local cluster. The top directory for embedding is /u/starofl/embedding . Under this directory there are several subdirectories of interest.
  • Those named after each production, e.g. P06ib which contain mixer macro and perl scripts
  • Common which contains further subdirectories lists and csh and a submission perl script
  • GSTAR which contains the kumac for running the simulation
Therefore you need to create a replica of this directory tree. From your home directory e.g. /u/user do
mkdir embedding
cd embedding
mkdir Common
mkdir Common/lists
mkdir Common/csh
mkdir GSTAR
mkdir P06ib
mkdir P06ib/setup

Now it needs populating with the relevant files. In the following /u/user/embedding as an example of your new embedding directory in your user home directory.

cd /u/user/embedding
cp /u/starofl/embedding/getVerticesFromTags_v4.C .
cp -R /u/starofl/embedding/P06ib/EmbeddingLib_v4_noFTPC/ P06ib/
cp /u/starofl/embedding/P06ib/Embedding_sge_noFTPC.pl P06ib/
cp /u/starofl/embedding/P06ib/bfcMixer_v4_noFTPC.C P06ib/
cp /u/starofl/embedding/P06ib/submit.starofl.pl P06ib/submit.user.pl
cp /u/starofl/embedding/P06ib/setup/Piminus_101_spectra.setup P06ib/setup/
cp /u/starofl/embedding/GSTAR/phasespace_P06ib_revfullfield.kumac GSTAR/
cp /u/starofl/embedding/GSTAR/phasespace_P06ib_fullfield.kumac GSTAR/
cp /u/starofl/embedding/Common/submit_sge.pl Common/


You now have all the files need to run embedding. There are further links to make but as you are going to export them to your own cluster you need to make the links afterwards.

Alternatively you can run embedding on PDSF from your home directory. There are a number of change to make first though because the various perl scripts have some paths relating to the starofl account inside them.

For those planning to export to a remote site you should tar and/or scp the data. I would recommend tar so that you can have the original package preserved in case something goes wrong. E.g.

tar -cvf embedding.tar embedding/
scp embedding.tar remoteuser@mycluster.blah.blah:/home/remoteuser

Obviously this step is unnecessary if you intend to run from your PDSF account although you may still want to create a tar file so that you can undo any changes which are wrong.

Login to your remote cluster and extract the archive. E.g
cd /home/remoteuser
tar -xvf embedding.tar

Script changes

The most obvious thing you will find are a number of places inside the perl scripts where the path or location for other scripts appears in the code. These must be changed accordingly.

P06ib/Embedding_sge_noFTPC.pl
  1.  changes to e.g.
     
    2. 

  2.  changes to e.g.
    3. 

  3.  changes to e.g.
    4. 

  4.  changes to e.g.
    5. 



P06ib/EmbeddingLib_v4_noFTPC/Process_object.pm


    

  1.  changes to e.g.
     
    2. 

  2.  changes to e.g.
     

    This is because the location of tcsh was different and probably will be for you too.
    3. 




Common/submit_sge.pl


    

  1.  changes to e.g.
     

    
Change relates to parsing the name of the directory with daq files in to extract the 'data vault' and 'magnetic field' which form part of job name and are used by Embedding_sge_noFTPC.pl (This may not make much sense right now and needs the detailed docs on each component. It is actually just a way to pass a file list with the same basename as the job). In the original script the path to the data is something like /dante3/starprod/daq/2005/cuProductionMinBias/FullField whereas on Bham cluster it is  /star/data1/daq/2005/cuProductionMinBias/FullField and thus the pattern match in perl has to change in order to extract the same information. If you have a choice then choose your directory names with care!
    2. 

  2.  changes to e.g.
    


    
Change relates to the line printing the job submission shell script that this perl script writes and submits. The first line had to be changed such that it can correctly be identified as a sh script. I am not sure how original can ever have worked?
    3. 

  3.  changes to e.g.

    This line prints part of the job submission script where the options for the job are specified. In SGE the job options can be in the file and not just on the command line. The extra options for Bham relate to our SGE setup. The -q option provides the name of the queue to use, otherwise it uses the default which I did not want in this case. The other extra options are to make the environment and working diretory correct as they were not the default for us. This is very specific to each cluster. If your cluster does not have SGE then I imagine extensive changes to the part writing the job submission script would be necessary. The scripts use the ability of SGE to have job arrays of similar jobs so you would have to emulate that somehow.
    4. 



No significant changes required for:

    

  • getVerticesFromTags_v4.C - none
    • 

  • GSTAR/phasespace_P06ib_fullfield.kumac, GSTAR/phasespace_P06ib_fullfield.kumac - actually there are changes but they only relate to redefining particle decay modes for (anti-)Ξ and (anti-)Ω to go 100% to charged modes of interest. This is only relevant for strangeness group
    • 

  • P06ib/bfcMixer_v4_noFTPC.C - checked carefully that chain3->SetFlags line actually sets the same flags since Andrew and I had to change the same flags e.g. add GeantOut option after I made orginal copy
    • 

  • P06ib/EmbeddingLib_v4_noFTPC/Chain_object.pm - none 
    • 

  • P06ib/EmbeddingLib_v4_noFTPC/EmbeddingUtilities.pm - there are lines where you may have to add the run numbers of the daq files which you are using so that they are recognised as either full field or reversed full field. In this example (Cu+Cu embedding in P06ib) the lines begin 
     and 
    . This is also something that Andrew and I both changed after I made the original copy.
    • 

  • P06ib/submit.user.pl - changes here relate to setup that you want to run and not to the cluster or directory you are using i.e. which setup file to use, what daq directories to use and any pattern match on the file names (usually for testing purposes to avoid filling the cluster with useless jobs) although you probably want to change the 
     line!
    • 

  •  P06ib/setup/Piminus_101_spectra.setup - any changes here relate to the simulation parameters of the job that you want to do and not to the cluster or directory you are using
    • 




Create links

A number of links are required. For example in the /u/starofl/embedding/P06ib there are the following links:

    

  • daq_dir_2005_cuPMBFF -> /dante3/starprod/daq/2005/cuProductionMinBias/FullField
    • 

  • daq_dir_2005_cuPMBRFF -> /dante3/starprod/daq/2005/cuProductionMinBias/ReversedFullField
    • 

  • daq_dir_2005_cuPMBHTFF -> /eliza5/starprod/daq/2005/cucuProductionHT/FullField/
    • 

  • daq_dir_2005_cuPMBHTRFF -> /eliza5/starprod/daq/2005/cucuProductionHT/ReversedFullField
    • tags_dir_cu_2005 -> /dante3/starprod/tags/P06ib/2005

  • tags_dir_cuHT_2005 -> /eliza5/starprod/embedding/tags/P06ib
    • 

  • data -> /eliza12/starprod/embedding/data
    • 

  • lists ->../Common/lists
    • 

  • csh-> ../Common/csh
    • 

  • LOG-> ../Common/LOG
    • 


You will therefore need similar links to where you store your daq files (and associated tags files) and where you want the output data to go.



That is it! Some things will probably need to be adapted to your circumstances but it should give you a good idea of what to do

Modified Birmingham Files

Production Management

   1) Usually embedding jobs are run in "HPSS" mode so the files end up in HPSS (via FTP). To transfer them from HPSS to disk copy the perl script ~starofl/hjort/getEmbed.pl and modify as needed. This script does at least two things that are not possible with, e.g., a command line hsi command: it only gets the files needed (usually the .geant and .event files) and it changes the permissions after the transfers. Note that if you do the transfers shortly after running the jobs the files will probably still be on the HPSS disk cache and transfers will be much fast than getting the files from tapes.



2) To clean up old embedding files make your own copy of ~starofl/hjort/embedAge.pl and use as needed. Note that $accThresh determines the maximum access time in days of files that will not be deleted.


   



  
Running Embedding

   This page describes how to run embedding jobs once the daq files and tags files are in place (see other page about embedding production setup).




Basics:


Embedding code is located in production specific directories: ~starofl/embedding/P0xxx. The basic job submission template is typically called submit.starofl.pl in that directory.


Jobs are usually run by user starofl but personal accounts with group starprod membership will work, too (but test first as the group starprod write permissions typically are not in place by default).

The script to submit a set of jobs is submit.[user].pl. The script should be modified to submit an embedding set from the the configuration file 

~starofl/embedding/[Production]/setup/[Particle]_[set]_[ID].setup
where
[Particle] is the particle type submitted (Piminus for GEANTID=9, as set inside file)
[set] is the file set submitted (more on this later)
[ID] is the embedding request number






Test procedure:

The best way to test a particular job configuration is to run a single job in "DISK" mode (by selecting a specific daq file in your submission). In this mode all of the intermediate files, scripts, logs, etc., are saved on disk. The location will be under the "data" link in the working directory. You can then go and figure out which script failed, hack as necessary and and try to make things work...

    This document is intended to provide all the information available for previous productions such that results for Quality Control studies and Productions Cross checks. Part of quality control studies include identification of missing/dead detector areas, distance of closest approach distributions (dca), and fit points distributions(Nfit). As part of production cross checks, some results in centrality dependance and efficiency are shown

    Adding a New Detector to STAR
    
   
    The STAR Geometry Model
    

    

    The STAR Geometry is implented in geant 3, which provides the geometry description to STAR's Monte Carlo application, starsim.   The geant3 model is
    

    implemented using the Advanced Geometry Interface for GSTAR language.   AGI provides a flexible and robust framework in which detector
    

    geometries can be quickly implemented.  STAR is currently migrating from the AGI language to a related framework called AgML.  AgML stands for
    

    "Another Geometry Modelling Language."  It is based on XML, and is the preferred language in which new geomtries should be implemented.   AgML
    

    provides backwards compatability with the AGI language, in order to continue supporting the starsim application as we transition to a new STAR virtual
    

    Monte Carlo application.

ID Truth
    

    
ID truth is an ID which enables us to determine which simulated particle was principally responsible for the creation of a hit in a detector, and eventually the physics objects (clusters, points, tracks) which are formed from them.  The StHit class has a member function which takes two arguements:
    

      
    
    • idTru -- the primary key of the simulated particle, i.e. "track_p" in the g2t hit structure
      • 
    
    • qaTru -- the quality of the truth value, defined as the dominant contributor to the hit, cluster, point or track.
      • 

    
Implementation of ID truth begins in the slow simulator.  Here, every hit which is created should have an ID truth value assigned.  
    

    
When hits are built up into clusters, the clustering algorithm should set the idtruth value for the cluster based on the dominant contributor of the hits which make up the cluster.
    

    
When clusters are associated into space points, the point finding algorithm should set the idtruth value for the point.  In the event that two clusters are combined with two different idTruth values, you should set idTruth = 0.

    • The STAR Geometry in simulation & reconstruction contains useful information on the detector  configurations associated with a unique geometry tag.  Production  geometry tags state the year for which the tag is valid, and a letter  indicating the revision level of the geometry.  For example, "y2009c"  indicates the third revision of the 2009 configuration of the  STAR detector.  Users wishing to run starsim in their private areas are  encouraged to use the most recent revision for the year in which they  want to compare to data.

    AgML Project Overview and Readiness for 2012
    

    


    

    
HOWTO Use Geometries defined in AgML in STARSIM
    
AgML geometries are available for use in simulation using the "eval" libraries. 
    
$ starver eval
    
The geometries themselves are available in a special library, which is setup for backwards compatability with starsim.  To use the geometries you load the "xgeometry.so" library in a starsim session, either interactively or in a macro:
    
starsim> detp geom y2012
    

    starsim> gexe $STAR_LIB/xgeometry.so
    
starsim> gclos all
    
 
    
HOWTO Use Geometries defined in AgML in the Big Full Chain
    
AgML geometries may also be used in reconstruction.  To access them, the "agml" flag should be provided in the chain being run:
    
e.g
    
 
    
root [0] .L bfc.C
    
root [1] bfc(nevents,"y2012 agml ...", inputFile);
    

     
    

    
    
        
    
            
            
    Geometry in Preparation: y2012
    
            
    Major changes:
    
            
    1. Support cone, ftpc, ssd, pmd removed.
    
            
    2. Inner Detector Support Module (IDSM) added                                                                  
    
            
    3. Forward GEM Tracker (FGTD) added
    
            
     
    
            
    Use of AgML geometries within starsim:
    
            
     
    
            
    $ starver eval
    
            
    $ starsim
    
            
    starsim> detp geom y2012
    
            
    starsim> gexe $STAR_LIB/xgeometry.so
    
            
    starsim> gclos all
    
            
     
    
            
    Use of AgML geometries within the big full chain:
    
            
    $ root4star
    
            
    root [0] .L bfc.C
    
            
    root [1] bfc(0,"y2012 agml ...",inputFile);

    AgML Tutorials
    
   
    Getting started developing geometries for the STAR experiment with AgML.
    

    Setting up your local environment
    

    You need to checkout several directories and complie in this order:

    

    $ cvs co StarVMC/Geometry
$ cvs co StarVMC/StarGeometry
$ cvs co StarVMC/xgeometry
$ cvs co pams/geometry
$ cons +StarVMC/Geometry
$ cons

    


    
This will take a while to compile, during which time you can get a cup of coffee, or do your laundry, etc...
    

    
If you only want to visualize the STAR detector, you can checkout:
    

    $ cvs co StarVMC/Geometry/macros
    

    Once this is done you can visualize STAR geometries using the viewStarGeometry.C macro in AgML 1, and the loadAgML.C macro in AgML 2.0.
    

    $ root.exe
root [0] .L StarVMC/Geometry/macros/viewStarGeometry.C root [1] nocache=true root [2] viewall=true root [3] viewStarGeometry("y2012") 
root [0] .L StarVMC/Geometry/macros/loadAgML.C
root [1] loadAgML("y2016")
root [2] TGeoVolume *cave = gGeoManager->FindVolumeFast("CAVE");
root [3] cave -> Draw("ogl");              // ogl uses open GL viewer



    

    Tutorial #1 -- Creating and Placing Volumes
    

    Start by firing up your favorite text editor... preferably something which does syntax highlighting and checking on XML documents.  Edit the first tutorial geometries located in StarVMC/Geometry/TutrGeo ...
    

    $ emacs StarVMC/Geometry/TutrGeo/TutrGeo1.xml

    

    This module illustrates how to create a new detector module, how to create and place a simple volume, and how to create and place multiple copies of that volume.  Next, we need to attach this module to a geometry model in order to visualize it.  Geometry models (or "tags") are defined in the StarGeo.xml file.  
    
 
    

    $ emacs StarVMC/Geometry/StarGeo.xml

    

    There is a simple geometry, which only defines the CAVE.  It's the first geometry tag called "black hole".  You can add your detector here...
    
 
    

    xxx
    


    
$ root.exe
    

    root [0] .L StarVMC/Geometry/macros/viewStarGeometry.C root [1] nocache=true root [2] viewStarGeometry("test","TutrGeo1");

    

    The "test" geometry tag is a very simple geometry, implementing only the wide angle hall and the cave.  All detectors, beam pipes, magnets, etc... have been removed.  The second arguement to viewStarGeometry specifies which geometry module(s) are to be built and added to the test geometry.  In this case we add only TutrGeo1.  (A comma-separated list of geometry modules could be provided, if more than one geometry module was to be built).
    

    Now you can try modifying TutrGeo1.  Feel free to add as many boxes in as many positions as you would like.  Once you have done this, recompile in two steps
    

    $ cons +StarVMC/Geometry
$ cons

    

    Tutorial #2 -- A few simple shapes, rotations and reflections
    

    The second tutorial geometry is in StarVMC/Geometry/TutrGeo/TutrGeo2.xml.  Again, view it using viewStarGeometry.C
    

    $ root.exe
root [0] .L viewStarGeometry.C
root [1] nocache=true
root [2] viewStarGeometry("test","TutrGeo2")

    

    What does the nocache=true statement do?  It instructs viewStarGeometry.C to recreate the geometry, rather than load it from a root file created the last time you ran the geometry.  By default, if the macro finds a file name "test.root", it will load the geometry from that file to save time.  You don't want this since you know that you've changed the geometry. 
    

    The second tutorial illustrates a couple more simple shapes:  cones and tubes.  It also illustrates how to create reflections.  Play around with the code a bit, recompile in the normal manner, then try viewing the geometry again.
    

    Tutorial #3 -- Variables and Structures
    

    
    
        
    
            
            
    AgML provides variables and structures.  The third tutorial is in StarVMC/Geometry/TutrGeo/TutrGeo3.xml.  Open this up in a text editor and let's look at it.   We define three variables: boxDX, boxDY and boxDZ to hold the dimensions of the box we want to create.  AgML is case-insensitve, so you can write this as boxdx, BoxDY and BOXDZ if you so choose.  In general, choose what looks best and helps you keep track of the code you're writing.
    
            
    Next check out the volume "ABOX".  Note how the shape's dx, dy and dz arguements now reference the variables boxDX, boxDY and boxDZ.  This allows us to create multiple versions of the volume ABOX.  Let's view the geometry and see.
    
            
    $ root.exe
root [0] .L StarVMC/Geometry/macros/viewStarGeometry.C
root [1] nocache=true
root [2] viewStarGeometry("test","TutrGeo3")

    
            
    Launch a new TBrowser and open the "test" geometry.  Double click test --> Master Volume --> CAVE --> TUTR.  You now see all of the concrete volumes which have been created by ROOT.  It should look like what you see at the right.  We have "ABOX", but we also have ABO1 and ABO2.  This demonstrates the an important concept in AgML.  Each <Volume ...> block actually defines a volume "factory".  It allows you to create multiple versions of a volume, each differing by the shape of the volume.  When the shape is changed, a new volume is created with a nickname, where the last letter in the volume name is replaced by [1 2 3 ... 0 a b c ... z] (then the second to last letter, then the third...). 
    
            
    Structures provide an alternate means to define variables.  In order to populate the members of a structure with values, you use the Fill statement.  Multiple fill statements for a given structure may be defined, providing multiple sets of values.  In order to select a given set of values, the <Use ...> operator is invoked.  In TutrGeo3, we create and place 5 different tubes, using the data stored in the Fill statements.
    
            
    However, you might notice in the browser that there are only two concrete instances of the tube being created.  What is going on here?  This is another feature of AgML.  When the shape is changed, AgML will look for another concrete volume with exactly the same shape.  If it finds it, it will use that volume.  If it doesn't, then a new volume is created.
    
            
    There's alot going on in this tutorial, so play around a bit with it.

    AgML vs AgSTAR Comparison
    
   
     Abstract: We compare the AgML and AgSTAR descriptions of recent revisions of the STAR Y2005 through Y2011 geometry models.  We are specifically interested in the suitability of the AgML model for tracking.  We therefore plot the material contained in the TPC vs pseudorapidity for (a) all detectors, (b) the time projection chamber, and (c) the sensitive volumes of the time projection chamber.  We also plot (d) the material found in front of the TPC active volumes.

    Decription of the Plots
    
            
    Below you will find four columns of plots, for the highest revision of each geometry from y2005 to the present.  The columns from left-to-right show comparisons of the material budget for STAR and its daughter volumes, the material budgets for the TPC and it's immediate daughter volumes, the material budgets for the active volumes in the TPC, and the material in front of the active volume of the TPC.  In the context of tracking, the right-most column is the most important.
    
            
    Each column contains three plots.  The top plot shows the material budget in the AgML model.  The middle plot, the material budget in the AgSTAR model.  The bottom plot shows the difference divided by the AgSTAR model.  The y-axis on the difference plot extends between -2.5% and +2.5%.
    
            
     --------------------------------
    
            

    
            Attached you will find much more comprehensive set of plots, contained in a TAR file.  PDF's for every subsystem in each of the following geometry tags are provided.  They show the material budget comparing AgML to AgSTAR for every volume in the subsystem.  They also show a difference plot, equal to the difference divided by the average.  There is a color-coding scheme.  The volume will be coded green if the largest difference is below 1%, red if it exceeds 1% over an extended range.  Yellow indicates a missing (mis-named) volume in one or the other geometry, and orange indicates a 1% difference over a small area (likely the result of roundoff error in alignments of the geometries).

    Beampipe support geometry and other news
    
   
    Documentation for the beampipe support geometry description development
    

    After the completion of the 2007 run, the SVT and the SSD were removed from the STAR detector along with there utility lines. The support structure for the beampipe remained, however.
    

    The following drawings describe the structure of the beampipe support as it exists in the late 2007 and probably throughout 2008

    Further corrections to the SVT geometry model
    

     
    

    In the course of recent discussion of the beampipe support and shield material, Dave Lynn has found that even though according to the plans, the material of the cooling water channels in the SVT was specified as Be, in reality carbon composite material was used for that purpose. Below, there are materil vs pseudorapidity plots for the "old" and "new" codes
    

     
    

    

     
    

    

     
    

    It can be seen that the difference is of the order of 0.4% rad. length on top of the existing (roughly) 6%. This is enough grounds for cutting a new version of the geometry and will shall create a geometry tag Y2007A which will reflect such change.

   Unless stated otherwise, all pp collisions are modeled with Pythia, and all AA collisions with Hijing. Statistics is listed in thousands of events. Multiplication factor in some of the records refelcts the fact that event mixing was done for a few types of particles, on the same base of original event files.

    Event Filtering
    
   
    The attached PDF describes event filtering in the STAR framework.
    
   
    

    
  
    Event Generators
    
   Event Generator Framework
    

 Example macros for running event generators + starsim in ROOT: 
    

    $ cvs co StRoot/StarGenerator/macros
    

      
    
    • starsim.pythia6.C
      • 
    
    • starsim.pythia8.C
      • 
    
    • starsim.hijing.C
      • 
    
    • starsim.herwig.C
      • 
    
    • starsim.pepsi.C
      • 
    
    • starsim.starlight.C
      • 
    
    • starsim.kinematics.C
      • 

    
To run an example macro and generate 100 events:
    

    $ ln -s StRoot/StarGenerator/macros/starsim.pythia8.C starsim.C
$ root4star -q -b starsim.C\(100\)

    
This will generate two files.  A standard "fzd" file, which can be reconstructed using the big "full" chain (bfc.C).  And a root file, containing a TTree expressing the event record for the generated events.
    

    
The new Event Record
    

    
The event-wise and particle-wise information from event generators is saved in a ROOT/TTree.  The TTree can be read in in sync with the MuDst when you perform your analysis.  The ID truth values in the reconstructed tracks in the MuDst can be compared to the primary key of the tracks in the event record to identify generator tracks which were reconstructed by the tracker.
    

    
The event record can be browsed using the standard ROOT ttree viewer.  Example for pythia 8:
    

    root [0] TFile::Open("pythia8.starsim.root")
root [1] genevents->StartViewer()
root [2] genevents->Draw("mMass","mStatus>0")

    
The event record contains both particle-wise and event-wise information.  For the definitions of different quantities, see the documentation provided in the StarGenEvent links above.
    

    

    

       
    
  
    Adding a new Generator
    
   Event generators are responsible for creating the final state particles which are fed out to GEANT for simulation.  They can be as simple as particle guns, shooting individual particles along well defined trajectories, or complex hydrodynamical models of heavy-ion collisions.  Regardless of the complexities of the underlying physical model, the job of an event generator in the STAR framework is to add particles to an event record.  In this document we will describe the steps needed to add a new event generator to the STAR framework.  The document will be divided into three sections: (1)  An overview, presenting the general steps which are required; (2) A FORtran-specific HOWTO, providing guidance specific to the problem of interfacing FORtran with a C++ application; and (3) A document describing the STAR event record.

1.0 Integrating Event Generators
    

    
The STAR Event Generator Framework implements several C++ classes which  facilitate the integration of FORtran and C++ event generators with the  STAR simulation code.  The code is available in the CVS repository and  can be checked out as

    $ cvs co StRoot/StarGenerator
    
After checking out the generator area you will note that the code is  organized into several directories, containing both CORE packages and  concrete event generators.  Specifically:
    

    
StarGenerator/BASE  -- contains the classes implementing the STAR interface to event generators
    
StarGenerator/EVENT -- contains the classes implementing the STAR event record
    
StarGenerator/UTIL  -- contains random number generator base class and particle data
    
StarGenerator/TEST  -- contains test makers used for validating the event generators
    

    
The concrete event generators (at the time this document was assembled) include
    

    
StarGenerator/Hijing1_383
    
StarGenerator/Pepsi
    
StarGenerator/Pythia6_4_23
    
StarGenerator/Pythia8_1_62
    

    
1.1 Compiling your Generator
    

    
Your first task in integrating a new event generator is to create a  directory for it under StarGenerator, and get your code to compile.    You should select a name for your directory which includes the name and version  of your event generator.  It should also be CamelCased...   MyGenerator1_2_3, for example.  (Do not select a name which is ALL CAPS,  as this has a special meaning for compilation).  Once you have your  directory, you can begin moving your source files into the build area.   In general, we would like to minimize the number of edits to the source  code to make it compile.  But you may find that you need to reorganize  the directory structure of your code to get it to compile under cons.   (For certain, if your FORtran source ends in ".f" you will need to  rename the file to ".F", and if your C++ files end in ".cpp" or ".cc",  you may need to rename to ".cxx".)
    

    
1.2 Creating your Interface
    

    
Ok.  So the code compiles.  Now we need to interface the event generation machinery with the STAR framework.  This entails several things.  First, we need to expose the configuration of the event generator so that the end user can generate the desired event sample.  We must then initialize the concrete event generator at the start of the run, and then exercise the event generation machinery on each and every event.  Finally, we need to loop over all of the particles which were created by the event generator and push them onto the event record so that they are persistent (i.e. the full event can be analyzed at a later date) and so that the particles are made available to the Monte Carlo application for simulation.
    

    
The base class for all event generator interfaces is  StarGenerator.  
    

    
Taking a quick look at the code, we see that there are several "standard" methods defined for configuring an event generator:
    

These methods have been defined in order to establish a common interface amongst all event generators in STAR.  These methods set variables defined within the class, from which you will initialize your concrete event generator.
    
You may need to implement additional methods in order to expose the configuration of your event generator.  You should, of course, do this.
    

    
The two methods which StarGenerator requires you to implement are Init() and Generate().  These methods will respectively be called at the start of each run, and during each event.
    

    
Init() is responsible for initializing the event generator.  In this method, you should pass any of the configuration information on to your concrete event generator.  This may be through calls to subroutines in your event generator, or by setting values in common blocks.  However this is done, this is the place to do it.
    

    
Generate() will be called on every single event during the run.   This is where you should exercise the generation machinery of your event generator.  Every event generator handles this differently, so you will need to consult your manual to figure out the details. 
    

    
Once Generate() has been called, you are ready to fill the event record.  The event record consists of two parts: (1) the particle record, and (2) the event-wise information describing the physical interaction being simulated.  At a minimum, you will need to fill the particle-wise information.  For more details, see The STAR Event Record  below.
    

    

    
2.0 Integrating FORtran Event Generators
    

    
Interfacing a FORtran event generator with ROOT involves (three) steps:
    

    
1. Interface the event generator's common blocks (at least the ones which we need to use) to C++
    
2. Map those common blocks onto C++ structures
    
3. Expose the C++ structures representing the common blocks to ROOT so that users may modify / access their contents
    

    
Let's look at the pythia event generator for a concrete example.  
    

    
If you examine the code in StRoot/StarGenerator/Pythia6_4_23/ there is a FORtran file named address.F.  Open that up in your favorite editor and have a look... You'll see several functions defined.  The first one is address_of_pyjets.  In it we declare the PYJETS common block, essentially just cutting and pasting the delcaration from the pythia source code in the same directory. 
       We use the intrinsic function LOC to return the address (i.e. pointer) to the first variable in the common block.  We have just created a FORtran function which returns a pointer to the data stored in this common block.  The remaining functions in address.F simply expose the remaining common blocks in pythia which we want access to.  By calling this function on the C++ side, we will obtain a pointer to the memory address where the common block resides. 
    

    
Next we need to describe the memory layout to C++.  This is done in the file Pythia6.h.  Each common block setup in address.F has a corresponding structure defined in this header file.  So, let's take a look at the setup for the PyJets common block:
    

    

      
    

    

    
First, notice the first line where we call the c-preprocessor macro "F77_NAME".  This line handles, in a portable way, the different conventions between FORtran and C++ compilers, when linking together object codes.  
    

    
Next, let's discuss "memory layout".  In this section of the code we map the FORtran memory onto a C-structure.   Every variable in the common block should be declared in the same order in the C struct as it was declared in FORtran, and with the corresponding C data type.  These are:

    INTEGER          --> Int_t
REAL             --> Float_t
REAL *4          --> Float_t 
REAL *8          --> Double_t 
DOUBLE PRECISION --> Double_t
    
You probably noticed that there are two differences with the way we have declared the arrays.  First, the arrays all were declared with an "_" in front of their name.  This was a choice on my part, which I will explain in a moment.  The important thing to notice right now is that the indicies on the arrays are reversed, compared to their declarion in FORtran.  "INTEGER K(4000,5)" in FORtran becomes "Int_t _k[5][4000]" in C++.  The reason for this is that C++ and FORtran represent arrays differently in memory.  It is important to keep these differences in mind when mapping the memory of a FORtran common block --
    

    
1) The indices in the arrays will always be reversed between FORtran and C --   A(10,20,30) in FORtran becomes A[30][20][10] in C.
    
2) FORtran indices (by default) start from 1, C++ (always) from 0 --  i.e. B(1) in FORtran would be B[0] in C.
    
3) FORtran indices may start from any value.  An array declared as D(-10:10) would be declared in C as D[21], and D(-10) in FORtran is D[0] in C.
    

    
What about the underscore?
    

    
We need to make some design choices at this point.  Specifically, how do we expose the common blocks to the end user?  Do we want the end user to deal with the differences in C++ and FORtran, or do we want to provide a mechanism by which the FORtran behavior (i.e. count from 1, preserve the order of indices) can be emulated.
    

    
My preference is to do the latter -- provide the end user functions which emulate the behavior of the FORtran arrays, because these arrays are what is documented in the event generator's manual.   This will minimize the likelyhood that the end user will make mistakes in configuring t he event generator.
    

    

    
So we have created a c-struct which describes how the common block's memory is laid out, and we have defined a function in the FORtran library which returns the location of the memory address of the common block.  Now we need to expose that function to C++.  To do that, we need to declare a prototype of the function.  There are two things we need to do.
    

    
First, we need to define the name of the subroutine in a portable way.  This is done using a macro defined in #include "StarCallf77.h" --
    

    
#define address_of_pyjets F77_NAME( address_of_pyjets, ADDRESS_OF_PYJETS )
    

    
Next we need to declare to C++ that address_of_pyjets can be found in an external library, and will return a pointer to the PyJets_t structure
    

    
extern "C" PyJets_t *address_of_pyjets();
    

    
Now we are almost done.  We need to add a function in our generator class which returns a pointer (or reference) to the common blocks, and we need to add PyJets_t to the ROOT dictionary... In MyGeneratorLinkDef.h, add the line
    

    
#pragma link C++ struct PyJets_t+;
    

    
Finally, you need to expose the FORtran subroutines to C++.  Again, take a look at the code in Pythia6.h and Pythia6.cxx.  In the header we declare wrapper functions around the FORtran subroutines, and in the implementation file we expose the FORtran subroutines to C++.
    

    
Our first step is declaring the prototypes of the subroutines and implementing the C++ infterface.  Consider the SUBROUTINE PYINIT in pythia, which  initializes the event generator.  In FORtran it is declared as
    

    
      SUBROUTINE PYINIT(FRAME,BEAM,TARGET,WIN)
    
      IMPLICIT DOUBLE PRECISION(A-H, O-Z)
    
      IMPLICIT INTEGER(I-N)
    
...
    
      CHARACTER*(*) FRAME,BEAM,TARGET
    

    

    
So the variables FRAME, BEAM and TARGET are declared as character variables, and WIN is implicitly a double precision variable.
    

    
There are several webpages which show how to interface fortran and c++, e.g. http://www.yolinux.com/TUTORIALS/LinuxTutorialMixingFortranAndC.html
    

    
It is really a system-dependent thing.  We're keeping it simple and only supporting Linux.  
    

    
#define pyinit F77_NAME(pyinit,PYINIT) /* pythia initialization */
    
extern "C" void   type_of_call  pyinit( const char *frame, 
    
                                        const char *beam, 
    
                                        const char *targ, 
    
                                        double *ener, 
    
                                        int nframe, 
    
                                        int nbeam, 
    
                                        int ntarg );
    

    
So there's three character varaibles declared: frame, beam and targ.  These correspond to the character variables on the FORtran side.  Also there's a double precision variable ener... this is WIN.   But then there are three integer variables nframe, nbeam  and ntarg.  FORtran expects to get the size of the character variables when the subroutine is called, and it gets them after the last arguements in the list.
    

    
Again, we would like to hide this from the end user... so I like to define wrapper functions such as 
    

    
#include <string>
    

    
void PyInit( string frame, string blue, string yellow, double energy )
    
{ 
    
   pyinit( frame.c_str(), blue.c_str(), yellow.c_str(), &energy, 
    
           frame.size(), 
    
           blue.size(), 
    
           yellow.size() ); 
    
}

    Material Budget Y2013
    
   
    
Material budget in the Y2013 (X) geometry.  The top left plots number of radiation lengths encounted by a straight track at the given eta, phi.  The top right (bottom left) compares the ROOT and STARSIM geometries generated by AgML plotted vs phi (eta).  These are averaged over the other variable.  ROOT geometry in black, STARSIM in red.  The bottom right shows the difference in ROOT - STARSIM geometries vs phi and eta.  Less than 0.01 radiation lengths difference found integrated over the entire cave.  
    

    

    Attached are material budget plots and differences for major subsystems.  Each PDF contains the material budget plots displaying number of radiation lengths averaged over all phi for the ROOT (left) and STARSIM (right) geometries created by AgML. The material difference plot is as described above.
    
   
    

    
  
    Miscellaneous production scripts
    
   
    This page has been created with the purpose to systematize the various scripts currently used in the Monte Carlo production and testing. The contents will be updated as needed, however the codes are presumed to be correct and working at any given time.
    
   
    
  
    Jobs catalog
    
   
    When running on rcas, we typically use a legacy csh script named "alljobs". It parses the job configuration file named "catalog" and dispatches a single job on the target node, which can be an interactive node if run interactively, or a batch node if submitted to a queue. The alljobs script expects to see the following directory structure: a writeable directory with the name of the dataset being produced, and directly under it, a writeable "log" directory, in which it would deposit the so-called token files, which serve two purposes:
    

      
    
    • help in sequential numbering of the output files 
      • 
    
    • in case of multiple input files (such as Hijing event files) allow to map N files to M jobs, thus managing the workload 
      • 

    

    The catalog file is effectively a table, in white-space separated format. Each line begins with the dataset name which is a three-letter acronym of the site name (and thus either rcf or pds) followed by a 4-digit serial number of the set. The alljobs script expects to find a directory named identically to the dataset, under the "job directory", which in the current version of the script is hardcoded as /star/simu/simu/gstardata. This, of course, can be improved or changed.
    

    The last field in each entry is used to construct the so-called tag, which plays an important role: it effectively defined the location of the Monte Carlo data in the HPSS, when the data is sunk there (this is done by a separate script). In addition, it also defines keys for the entries in the FileCatalog (reconstructed data). The alljobs script creates a file of zero length, with a name which is a period-separated catenation of the word "tag" and the contents of the last column in the line.
    

    Here are the contents of the catalog file as it existed from the late 1990-s to the end of 2006

    When submitting jobs on the Grid, most of the functionality in alljobs is redundant. The simplified scripts can be found in the "Grid-Friendly" section of this site.
       
    

    
  
    Merger/filtering script
    
   Typically, a Starsim run will result in an output which is a file, or a series of files with names like gstar.1.fz, gstar.2.fz  etc. Regardless of whether we run locally or on the Grid, there is a small chance that the file(s) will be truncated. To guard against the possibility of feeding up incorrect data to the reconstruction stage, and/or performing a split or merger of a few file, a KUMAC script has been developed. It will, among other things, discard incomplete events, and produce serially numbered files with names like rcf1319_01_100evts.fzd, which contains the name of the dataset, the serial number of the file (distinct from the numbering of the input files), and the number of events contained therein, all of which is helpful in setting up or debugging the production. It has recently been simplified (although still not easily readable), and wrapped into a utility shell script, which does preparation work as well as cleanup. The resulting script, named "filter.tcsh", takes a single argument which is assumed to be the name of the dataset (and which is then used in naming the output files).

   New event generators are now being implemented in a C++ framework, enabling us to run simulations within the standard STAR, ROOT-based production chain.  Running these generators requires us to migrate away from the familiar starsim interface and begin running simulations in root4star.  Several example macros have been implemented, showing how to run various event generators and how to produce samples of specific particles.  This HOWTO guide illustrates one of these examples.
    

    
First, obtain the example macro by checking it out from cvs:
    

    $ cvs co StRoot/StarGenerator/macros
$ cp StRoot/StarGenerator/macros/starsim.kinematics.C .
    
Running the macro is straightforward.  To generate 100 events, simply do...

    $ root4star
root [0] .L starsim.kinematics.C
root [1] int nevents = 100
root [2] starsim(nevents)

    
This will create an "fzd" file, which can be analyzed with the bfc.C macro as you normally would.
    

    
If you're happy with 9 muons per event, thrown with a funky pT and eta distribution, run with the 20012 geometry... then you can use the macro as is.  Otherwise, you'll want to modify things to suit your needs.   Open the macro in your favorite editor (i.e. emacs or vi).  In the "starsim" function, somewhere around line 108, you should see the following lines:
    

      geometry("y2012");
  command("gkine -4 0");
  command("gfile o pythia6.starsim.fzd");
    


    
If you're familiar with the starsim interface, you probably recognize the arguements to the command function.  These are KUIP commands used to steer the starsim application.   You can use the gfile command to set the name of the output file, for example.  The "gkine -4 0" command tells starsim how it should get the particles from the event generator (this shouldn't be changed.)  Finally, the geometry function defined in the macro allows you to set the geometry tag you wish to simulate.  It is the equivalent of the "DETP geom" command in starsim.  So you may also pass magnetic field, switch on/off hadronic interactions, etc.  Any command which can be executed in starsim can be executed using the "command" function.  This enables full control of the physical model, the ability to print out hits, materials, etc... and setup p
    

    
Let's take a quick look at the "KINE" event generator and how to configure it.  StarKinematics is a special event generator, allowing us to inject particles into the simulation on an event-by-event basis during a simulation run.  The "trig" function in this macro loops over a requested number of events, and pushes particles.  Let's take a look a this function.
    
 
    

    void trig( Int_t n=1 )
{
  for ( Int_t i=0; i<n; i++ ) {

    // Clear the chain from the previous event
    chain->Clear();

    // Generate 1 muon in the FGT range
    kinematics->Kine( 1, "mu-", 10.0, 50.0, 1.0, 2.0 );

    // Generate 4 muons flat in pT and eta 
    kinematics->Kine(4, "mu+", 0., 5., -0.8, +0.8 );

    // Generate 4 muons according to a PT and ETA distribution
    kinematics->Dist(4, "mu-", ptDist, etaDist );

    // Generate the event
    chain->Make();

    // Print the event
    primary->event()->Print();
  }
}
    

    The "kinematics" is a pointer to a StarKinematics object. There are three functions of interest to us:
    

      
    
    • Kine -- Throws N particles of specified type flat in pT, eta and phi
      • 
    
    • Dist -- Throws N particles of specified type according to a pT and eta distribution (and optionally phi distribution) defined in a TF1.
      • 
    
    • AddParticle -- Creates a new particles and returns a pointer to it.  You're responsible for setting the identity and kinematics (px, py, pz, etc...) of the particle.
      • 

    
In the example macro, we generate a single muon thrown flat in pT from 10 to 50 GeV, and 1 < eta < 2.  We add to that 4 muons thrown flat 0 < pT < 5 GeV  and |eta|<0.8.  And 4 more muons according to pT and eta distributions defined elsewhere in the code.  After calling "Make" on the big full chain, we print out the resulting event.

    The printout above illustrates the STAR event record.  Each row denotes a particle in the simulation.  The 0th entry (and any entry with a status code -201) is used to carry summary information about the configuration of the event generator.  Multiple event generators can be run in the same simulation, and a Rootino is introduced into the event record to summarize their configuration.  The three columns at the left hold the primary event id, the generator event id, and the idtruth id.  The next column shows the PDG id of the particle, followed by the particle's name.  The particle's staus code is next, followed by the 4-momentum and mass, and the particle's start vertex.  Finally, the last four columns denote the primary ids of the 1st and last mother particle and the 1st and last daughter particle.
    

    
The STAR event record is saved in a ROOT file at the end of the simulation run, allowing you to read back both particle-wise and event-wise information stored from the event generator and compare with reconstructed events.  Here, the idtruth    ID of the particle is useful, as it allows you to compare reconstructed tracks and hits with the particle which generated them.
       
    


    
  
    Simulation HOWTOS
    
   
    STARSIM is the legacy simulation package in STAR, implemented in FORtran, MORtran and utilizing GEANT3 as the concrete MC package.    For documentation on how to run simulations using STARSIM, see
    


    The simulation group is evolving the framework towards using Virtual Monte Carlo.  As a first step, we have implemented a new event generator framework which will be compatible with the future VMC application.  The new framework allows us to run jobs within root4star.  In order to run simulations in the new framework, see

    Introduction
    

    
STAR's simulation infrastructure is built around the GEANT 3 simulation package.  It is implemented in FORtran, augmented by the MORtran-based AgSTAR preprocessor language, with a ROOT and C++ interface which allows it to be integrated with our standard "big full chain" software.  The legacy documentation pages describe how to run starsim as a standalone application.  The purpose of this document is to describe how to run simulations using the modern C++ interface, and to serve as a starting point for extending the simulation infrastructure with additional geometry modules, event generators, and slow simulators.
    

    
This document assumes familiarity with:

Running your analysis code over Monte Carlo data samples is generally a three step process.  First you'll need to generate your Monte Carlo events by running the simulation package.  Then you'll pass these events through the reconstruction software to convert MC hits to "real" ones, then perform track reconstruction, matching to TOF/MTD/etc... and creating calorimeter hits.  Finally you will want to run your analysis code on the output, possibly even looking at the Monte Carlo Truth tables in order to better understand the efficiency, purity and resolution of your reconstruction codes.
    

    

    A. Your First Simulation Job
    

    
We're going to start with a simple example:  starsim.kinematics.C.  This is an example macro which runs under root4star, and generates a sample of muons and neutral pions.  Start by checking the code out from CVS. 
    

    $ cvs co StRoot/StarGenerator/macros/starsim.kinematics.C                 # check out the macro
$ ln -s StRoot/StarGenerator/macros/starsim.kinematics.C starsim.C        # create a link named starsim.C
$ root4star starsim.C                                                     # run the code using STAR's version of ROOT

    
You're going to see alot of output here, but in the end you'll have two output files:  starsim.kinematics.root and starsim.kinematics.fzd
    

    $ ls
starsim.kinematics.fzd
starsim.kinematics.root
starsim.C
StRoot/
    

    These two files are the so called "zebra" file (.fzd), containing the Monte Carlo hits, geometry and other associated event information, and the event generator record (.root), containing a ROOT TTree which saves all of the particles generated by the primary event generator. 
    

    B. Reconstructing the Events
    


    
Once we have the output files, it's time to run them through the reconstruction chain.  STAR's reconstruction code is steered using the "big full chain" macro bfc.C.  For most jobs you'll want to provide BFC three arguements:  the number of events to produce, the set of chain options to run, and an input file.  For more complicated tasks you're encouraged to ask questions on the STAR software list.
    

    Below you'll find an example macro which runs the big full chain.  We're going to run a limited set of STAR software to begin with.  Start by looking at line 12.  This is where the big full chain is called.  As I noted above, it takes three arguements.  The first is the number of events to process... coincidentally, 10 is the number of events which starsim.kinematics.C produces by default.  Then it takes two strings as input.  The first is the set of chain options we want to run.  It's a long list, so I've broken things down across several lines.  
    

    
Line 5 specifies the geometry tag to use.  Generally the format is the letter "r" followed by a valid STAR Geometry in simulation & reconstruction.
    
Line 6 specifies the geometry model to use.  Generally you need to specify both "agml" and "UseXGeom" here.  (More on this later).  BTW, did you notice that capitalization is ignored?  
    
Line 7 tells the big full chain that the input will be a zebra file.  This is our standard for now.
    
Line 8 sets up the TPC simulator.  We perform our digitization of the geant hits in the reconstruction chain.  This is where the TPC hits are converted to ADC values used as input to the reconstruction codes.
    
Line 9 sets up the track finding and reconstruction codes.  We're using "sti" and "ittf" here.
    
Line 10 most STAR analyses use the micro DST.  This flag creates it.
    
Line 11 the "fzd" file contains an event record, which associates MC hits with generated tracks.  This will allow us to (much later) associate the reconstructed tracks with the true Monte Carlo particles from which they came.
    

    $ emacs runBfc.C                    # Feel free to use your favorite editor instead of emacs
0001 | void runBfc() {
0002 |   gROOT->LoadMacro("bfc.C");                  // Load in BFC macro
0003 |   TString _file = "kinematics.starsim.fzd";   // This is our input file
0004 |   TString _chain;                             // We'll build this up
0005 |   _chain += "ry2012a ";                       // Start by specifying the geometry tag (note the trailing space...)
0006 |   _chain += "AgML USExgeom ";                 // Tells BFC which geometry package to use.  When in doubt, use agml.
0007 |   _chain += "fzin ";                          // Tells BFC that we'll be reading in a zebra file.
0008 |   _chain += "TpcFastSim ";                    // Runs TPC fast simulation
0009 |   _chain += "sti ittf ";                      // Runs track finding and reconstruction using the "sti" tracker
0010 |   _chain += "cmudst ";                        // Creates the MuDst file for output
0011 |   _chain += "geantout ";                      // Saves the "geant.root" file
0012 |   bfc(10, _chain, _file );                    // Runs the simulation chain
0013 | }
ctrl-x ctrl-s ctrl-x ctrl-q          # i.e. save and quit
$ root4star runBfc.C                 # run the reconstruction job
$ ls -l
...


    

    If all has gone well, you now have several files in your directory including the MuDst which you'll use in your analysis.
    

    $ ls -1 *.root
kinematics.geant.root
kinematics.hist.root
kinematics.MuDst.root
kinematics.runco.root
kinematics.starsim.root

    


    
C. idTruth and qaTruth
    

    
During the first phase of the simulation job we had full access to the state of the simulated particles at every step as they propagated through the STAR detector.  As particles propagate through active layers, the simulation package can register "hits" in those sensitive layers.  These hits tell us how much energy was deposited, in which layer and at what location.  They also save the association between the particle which deposited the energy and the resulting hit.  This association is saved as the "idTruth" of the hit.  It corresponds to the unique id (primary key) assigned to the particle by the simulation package.  This idTruth value is exceedingly useful, as it allows us to compare important information between reconstructed objects and the particles which are responsible for them.
    

    
Global and Primary tracks contain two truth variables:  idTruth and qaTruth.  idTruth tells us which Monte Carlo track was the dominant contributor (i.e. provided the most TPC hits) on the track, while qaTruth tells us the percentage of hits which thath particle provided.  With idTruth you can lookup the corresponding Monte Carlo track in the StMuMcTrack branch of the MuDst.  In the event that idTruth is zero, no MC particle was responsible for hits on the track.  
    
With the MC track, you can compare the thrown and reconstructed kinematics of the track (pT, eta, phi, etc...).
    

    
Primary vertex also contains an idTruth, which can be used to access the Monte Carlo vertex which it corresponds to in the StMuMcVertex branch of the MuDst.
    

    
D. Taking it further
    

    
In starsim.kinematics.C we use the StarKinematics event generator, which allows you to push particles onto the simulation stack on an event-by-event basis.  You can throw them flat in phase space, or sample them from a pT and eta distribution.  These methods are illustrated in the macro, which throws muons and pions in the simulation.  You can modify this to suit your needs, throwing whatever particles you want according to your own distribtions.  The list of available particles can be obtained from StarParticleData.
    
 
    

    $ root4star starsim.C\(0\)
root [0] StarParticleData &data = StarParticleData::instance();
root [1] data.GetParticles().Print()

    

    Additionally, you can define your own particles.  See starsim.addparticle.C.

    The Truth about Event Records
       
    

    
  
    StMc package
    
   
       StMc package create StMcEvent structure and fills it by Monte-Carlo information. Then  create StMiniMcEvent structure
    
which contains both, MonteCarlo & Reconstruction information. Then provide matching MonteCarlo & Reconstruction info.
    
It allows user to estimate quality of reconstruction and reconstruction efficiency for different physical processes.
    
Actually, StMcEvent is redundunt, and exists by historical reasons.
    
StMc consists of:
    

      

    • StMcEvent - structure with MonteCarlo(Simu) information;
      • 

    • StMiniMcEvent - structure with both Simu & Reco info;
      • 

    • StMcEventMaker - maker creates and fill StMcEvent Simu info;

    Hijing
    
   
    To use Hijing for simulation purposes, one must first run Hijing proper and generate event files, then feed these data to starsim to complete the GEANT part.
    

    The Hijing event generator codes and makefile can be found in the STAR code repository at the following location:$STAR/pams/gen/hijing_382. Once built, the executable is named hijjet.x. The input file is called hijev.inp and should be modified as per user's needs. When the executable is run multiple times in same directory, a series of files will be produced with names like evgen.XXX.nt, where XXX is an integer. The format of the file is PAW Ntuple. The starsim application is equipped to read that format as explained below. If a large number of events are needed, a request should be made to the STAR simulation leader or any member of the S&C.
    

    Listed below is the KUMAC macro that can be used to run your own GEANT simulation with pre-fabricated Hijing events . Unlike the Pythia simulation, events aren't generated on the fly but are read from an external file instead. Look at the comments embedded in the code. Additional notes: 
    

      
    
    • don't forget to seed the random number generator if you'll be doing a series of runs 
      • 
    
    • make sure you specify the correct geometry tag 
      • 
    
    • specify a different output file for each run 
      • 
    
    • the location of the input file (current directory) and the name (evgen.1.nt) are given as an example 
      • 
    
    • you can browse the directory /star/simu/evgen to look at what input Hijing files are already available 
      • 
    
    • the number of triggers on the bottom of the macro can be set to anything, just remember that the resulting files can be large and unwieldy if that number is too large. As a rule of thumb, we usually don't go over 500 events per file in production for min-bias AuAu, and 100 event for central gold

    Introduction
    
There are two ways, which are slightly different, to run the Pythia event generator in the context of the Starsim application. In the original (old) design, the dynamic library apythia.so served both as an adapter and a container for the standard Pythia library that would typically come with a CERNLIB distribution. The problem with this approach is of course that Pythia in itself is not a static piece of software and receives periodic updates. It is difficult or impossible, therefore, to modify the apythia.so component without affecting, in one way or another, various analyses as the consistency of the code is broken at some point.
    
It possible, however, to refactor the Pythia adaptor in such a way that the Pythia library proper can be loaded separately. This gives the user the ability to choose a specific version of the Pythia code to be run in their simulation. Different users, therefore, can use different versions of Pythia concurrently in Starsim, which is in everybody's interest. The thus modified wrapper was given the mneumonic name bpythia.so (it should be easy to memorize since "b"-pythia follows "a"-pythia). We have also decided the freeze the Pythia version linked into apythia.so at 6.205, and select subsequent versions bpythia.so as explained on the bottom of this page.
    

In the following, we present both the "old way" of running Pythia (i.e. tied to a specific version) and the new one (whereby the version can be requested dynamically at run time).
    


    Using Pythia 6.205
    
Listed below is the KUMAC macro that can be used to run your own Pythia simulation, specifically utilizing version 6.205 of the Pythia code and without the ability to switch. This would be fine for most STAR applications at the time of this writing (mid-2007). Please pay attention to the comments embedded in the code.
Additional notes:

      

    • the script below explicitely refers to apythia.so which contains Pythia 6.205
      • 

    • don't forget to seed the random number generator if you'll be doing a series of runs
      • 

    • make sure you specify the correct geometry tag
      • 

    • specify a different output file for each run
      • 

    • pay attention to the physics parameters used in the simulation; you will need to consult the Pythia manual for meaning fo those
      • 

    • the number of triggers on the bottom of the macro can be set to anything, just remember that the resulting files can be large and unwieldy if that number is too large. As a rule of thumb, we usually don't go over 5k event per file in production

    Specifying the Pythia version dynamically
    
In addition to the "frozen" version 6.205 which can be used as explained above, there is currently one more version that can be loaded, namely 6.410. Going forward, more versions will be added to the code base and to the collection of STAR libraries, as needed.
    
In order to use version 6.410, the user needs to simply replace the following line in the above script

    gexec $STAR_LIB/apythia.so

    
With:

    gexec $STAR_LIB/libpythia_6410.so
gexec $STAR_LIB/bpythia.so

    

   
    

    
  
    The Magnetic Monopole in STAR
    
   
    Introduction
    

    It is possible to simulate the production and propagation of the magnetic monopoles in the STAR experiment, using a few modification in the code base of GEANT 3.21, and in particular in our GEANT-derived application, the starsim. Our work is based on a few papers, including: 
    

The flow of the GEANT code execution is illustrated by the following diagrams from the above publication:

     
    

    

     
    

     
    

     
    

    First Results
    
As as demonstration of principle, we present here a few Starsim event display pictures. First, we propagate 12 magnetic monopoles of varying momenta, in the STAR detector:

     
    

    

     
    

    Now, let's take a look at a minimum bias gold-gold event that contains a pair of magnetic monopoles:
    

     
    

    

     
    

    Salient features can already be seen in these graphics: large dE/dx losses and characteristic limit on the maximum radius of the recorded monopole track (this is due to the fact that the trajectory of the mm is not helix-like, but rather parabole-like). Now, lets take a look at the phi distribution of the hits, for central and peripheral gold-gold events containing monopoles: 
    

     
    

    

     
    

    

     
    

    Again, the rather intuitive feature (large peaks in phi due to a very large dE/dx produced by the monopoles) is obviously borne out in the simulation.
    

     
    

    This is work in progress and this page is subjec to updates. 
       
    

    

    
  
    Grid-friendly Starsim production scripts
    
   Since the production activity of STAR is migrating to, and eventually will end up running mostly in the Grid environment, this necessitates modification (which often means simplification) of the production scripts we use when running on a local or another "traditional" Unix farm facility. Here is an example of the script we have successfully used to run a Pythia simulation on the Grid (utilizing the Fermilab facility), as well as the SunGrid, with cosmetic modifications.
    
A few things worth noting:

      

    • The bulk of the script has to do with establishing the Pythia settings which are often required in the simulations requested by the Spin PWG; the starsim proper part is located on top is is uncomplicated; it invloves dynamic loading of the necessary libraries, setting up the beam interaction diamond parameters ets
      • 

    • The script needs the contents of the tarball (listed on the bottom of the page) located in its working directory; this "payload" contains the Starsim executable as well as a few shared libraries and accessory scripts necessary for its function. To be able to run on the Grid, therefore, on needs to
        

      • Transfer the tarball and make provisions for extraction of the files
        • 

      • Transfer the script below and configure it for submission with a unique serial number (any integer, really)

      


      • 

    • The script takes only one argument, which is the serial number of the run. The rest of the run parameters are encoded in its body, which minimizes the chances of human error when submitting a large number of scripts, potentially for many different datasets
      • 

    • The random number generator is seeded with the serial run number and with the Unix process ID of the script on the target machine, which for all intents and purposes guarantees the uniqueness of a sequence in each run
