evaluation of TpcRS (new TPX slow simu)

Updated on Thu, 2009-11-05 17:36. Originally created by balewski on 2009-11-02 10:05.

A)----- Au+Au events @  sqrt(s)=200 GeV, no pileup simulation

Events samples were generated by Wei-Ming using: sqrt(s)=200 GeV, Relativistic Quantum Molecular Dynamics (RQMD), geometry 2009

Events's sets, 20 events apiece:

minB : Impact parameter b goes from 0 to 15 fm 

peripheral (b > 13 fm); mid (9 fm < b < 11 fm), and   cent (b < 5 fm)

AuAu events, BFC w/ TpcRs
event set   avr # of good glob   CPU per eve   
 minB  770 tracks/eve  20 min  
peripheral  12 tracks/eve  44 sec  
mid  360 tracks/eve  11 min  
central  2400 tracks/eve  53 min  

The largest time consumers in BFC w/ TpcRS for minB data set of 20 events:

The following BFC chain was used:

B)----- U+U events @  sqrt(s)=200 GeV, no pileup simulation

Events samples were generated by We Kejun in IOPP using: sqrt(s)=200 GeV,  RQMD, geometry 2009, the deformation for U hasn't been considered, minB collisions.

C)---- P+P events @ sqrt(s)=500 GeV, includes pileup simulation

Estimation of time needed to simulate pp500 events w/ pileup. Based on T. Roser CAD projection we expect peak lumi as follows. 

Table 1  CPU per M-C pp500 events w/ pileup
year  test 1  test 2  2009   2011   2012  2013 2014
peak lumi (10^30/cm^/s) 4 20 85 169 250 338 417
# of minB inter. per bXing  0.01  0.05 0.21   0.42  0.63 0.85  1.0 
 # of good glob tracks  50-150  360-500  1.9K        13-15K
 CPU time per event (BFC w/ TpcRS) *)  3 min  11 min  42 min        3.5 hours
 CPU time per event (BFC w/ TRS) **)  0.27 min  0.9 min  3.2 min        0.26 hours

*) averaged over 5 events. **)  averaged over 100,20,10,10 events, respectively.

All timing was measured on rcas6001 where I got ~100% CPU per process, on the same Pythia events w/ partonic pt>20 GeV. Pileup were Pythia events w/ partonic pt>1 GeV. Events were generated with y2009 geometry as in dev on Nov. 1 2009.

This BFC chain was used to simulate 5% pileup BFC w/ TpcRS (new TPX sloe simu):

 Similar test were done using BFC w/ TRS (current TPC slow simu) , 1% pileup:
