. Various scientific groups at SLAC submit funds contribute to the purchase these of the general farm batch systems and jobs submitted to run in the general farm are scheduled according to a fairshare priority structure. If you are not part of a computing group that has a fairshare, your jobs will run according to the priority of the group called AllUsers.
Submitting Jobs to the General Farm
To submit jobs to the general farm you will need to
- have a SLAC unix account

This command will submit your job to the first available general farm machine and will be able to run for 30 minutes of wall clock time. It is recommended to run your job specifying a wall clock time since LSF can
