Depending on your data access you may need to submit jobs to a specific farm. This is accomplished by submitting to the appropriate LSF batch queue. Refer to the table below. Jobs for the running experiment should be submitted to high priority queues psnehq and psfehq. Multi-core OpenMPI jobs should be run in either the psnehmpiq or psfehmpiq batch queue, see the following section on "Submitting OpenMPI Batch Jobs". Simulation jobs should be submitted to the low priority queues psfehidle and psfehidle. CPU intensive jobs which don't demand high data throughout should be submitted to the psanacsq queue.

Submitting Batch Jobs

LSF (Load Sharing Facility) is the job scheduler used at SLAC to execute user batch jobs on the various batch farms. LSF commands can be run from a number of SLAC servers, but best to use psexport or pslogin. Login first to {{pslogin}} (from SLAC) or to {{psexport}} (from anywhere). From there you can submit a job with the following command:

...

This will submit a job (my_program) to the queue queue psnehq and and write its output to a file named ~/output/job.out.  You You may check on the status of your jobs using the the bjobs command command.

Resource requirements Resource requirements can be specified using the "-R" option.  For For example, to make sure that a job is run on a node with 1 GB (or more) of available memory, use the following: 

bsub -q psnehq -R "rusagemem=1024" my_program
