LSF Version 7.3 - Using Platform LSF HPC

Submitting Open MPI Jobs
bsub command
Use bsub -a openmpi to submit jobs.
For example:
bsub -a openmpi -n number_cpus mpirun.lsf a.out
◆ -a openmpi tells esub the job is an Open MPI job and invokes esub.openmpi.
◆ -n number_cpus specifies the number of processors required to run the job
◆ mpirun.lsf reads the environment variable LSF_PJL_TYPE=intelmpi set by
esub.openmpi, and generates the appropriate pam command line to invoke
Open MPI as the PJL
Task geometry with Open MPI jobs
Open MPI supports the LSF task geometry feature
Submitting a job with a job script
A wrapper script is often used to call Open MPI. You can submit a job using a job script
as an embedded script or directly as a job, for example:
bsub -a < jobscript
Your job script must use mpirun.lsf in place of the mpirun command.
