Submitting Parallel Jobs
LSF can allocate more than one host or processor to run a job and automatically keeps
track of the job status, while a parallel job is running.
Specifying the number of processors
When submitting a parallel job that requires multiple processors, you can specify the
exact number of processors to use.
To submit a parallel job, use
bsub -n and specify the number of processors the job
requires.
To submit jobs based on the number of available job slots instead of the number of
processors, use
PARALLEL_SCHED_BY_SLOT=Y in lsb.params.
Example % bsub -n 4 myjob
This command submits myjob as a parallel job. The job is started when 4 job slots are
available.
