Initial Setup

First things first. I went to http://www2.lns.mit.edu/compserv/cms-acctappl.html and applied for a local account. The welcome message contained a link to the CMSAF User Guide found on this TWiki page.

AFS isn’t available on CMSAF, so I started a local tree at /osg/app/star/afs_rhic and began to copy over stuff. Here’s a list of what I copied so far (nodes are running SL 4.4):

I copied these precompiled libraries over instead of building them myself because of a tricky problem with the interactive nodes’ configuration. The main gateway node is a 64-bit machine, so regular attempts at compilation produce 64-bit libraries that we can’t use. CMSAF has a node reserved for 32-bit builds, but it’s running SL 3.0.5. We’re still working on a proper resolution of that problem. Perhaps we can force cons to do 32-bit compilations.

The environment scripts are working, although I had to add more hacks than I thought were necessary. I only changed the following files:

1. ~/.login
2. ~/.cshrc
3. $GROUP_DIR/site_post_setup.csh

It doesn’t seem possible to change the default login shell (chsh and ypchsh both fail), so when you login you need to type “tcsh” to get a working STAR environment (after copying my .login and .cshrc to your home directory, of course).

Basic interactive tests look good, and I’ve got a SUMS configuration that will do local job submissions to the Condor system (that’s a topic for another post). DB calls use the MIT database mirror. I think that’s all for now.

STAR Scheduler Configuration

I deployed a private build of SUMS (roughly 1.8.10) on CMSAF and made the following changes to globalConfig.xml to get local job submission working:

In the Queue List

In the Policy List

Now for the Dispatcher

And finally, here's the site configuration block
