Batch Jobs

One Time Setup

Email the mighty administrator requesting access to the queues, along with your SLAC account name. It might take a couple of hours to add you to the appropriate permissions lists.

Add the following line to your .cshrc file:

setenv PATH ${PATH}:/afs/slac/g/suncat/bin

If you have a line like the following in .cshrc remove it:

eval `/usr/local/bin/environ /bin/tcsh -i${?prompt} -e emacs:vi`

Queues

Submitting Jobs

It is important to have an "afs token" before submitting jobs. Check the status with the tokens commands. Renew every 24 hours with kinit command.

Login to any suncat machine (e.g. suncat0001) to execute commands like these:

gpaw-bsub -o mo2n.log -q <qname> -n 8 gpaw-python mo2n.py 
dacapo-bsub -o Al-fcc-singlelog -q <qname> -n 8 Al-fcc-single.py

NOTE: Because of a file-locking bug in afs, all output from GPAW should go to nfs. When the full farm arrives we will have our own NFS space. In the meantime, you can create your own temporary directory in /nfs/slac/g/suncat.

Useful Commands

Login to any suncat machine (e.g. suncat0001) to execute these.
