Using the SLAC computing resources

You need a SLAC Unix account to utilize the shared analysis computing facility (ACF). If you do not have such an account, please follow the instructions here

Please subscribe to the CERN e-group used for announcements and discussions specific to the SLAC ACF. Go to the CERN e-group search web page, enter the group name atlas-us-slac-acf, and subscribe yourself. If you do not have access to the search page, email Wei Yang with your email address to be added to the group. 

The following is a quick summary to get you login and started. Here are more information on SLAC computing resource specific for ATLAS users.

Login to SLAC

SLAC provides a pool of login nodes with CVMFS and Grid tools. To that extend, the environment is similar to the LXPLUS cluster at CERN. You can access them by ssh to rhel6-64.slac.stanford.edu

Disk Space

SLAC provides new ATLAS users with two personal storage areas:

  • Home directory /gpfs/slac/atlas/fs1/u/<user_name>. This space is backed up to tape, and there is a quota of 100 GB. 
  • Data directory /gpfs/slac/atlas/fs1/d/<user_name>. This space is not backed up. There is an initial quota of 2 TB. You can request an increase, up to 10 TB, by sending email to Unix Admin

Existing ATLAS users with previous setups who want to move their home directories to GPFS and get GPFS data directory should email Wei Yang

 

Unix Mail Forwarding

Please set up a Unix .forward file so emails generated automatically in the Unix system such as batch job notification, cron job results, etc are forwarded to your preferred email location. For example, put a line in $HOME/.forward that reads 

your_name@domain.earth

or if your prefered email is a SLAC Exchange addresss

your_name@exchange.slac.stanford.edu
