LSF Version 7.3 - Using Platform LSF HPC

Examples
To run a job and have LSF select the host, the command:
mpirun -np 4 a.out
is entered as:
bsub -n 4 pam -mpi -auto_place a.out
To run a single-host job and have LSF select the host, the command:
mpirun -np 4 a.out
is entered as:
bsub -n 4 -R "span[hosts=1]" pam -mpi -auto_place a.out
To run a multihost job (5 processors per host) and have LSF select the hosts, the
following command:
mpirun hosta -np 5 a.out: hostb -np 5 a.out
is entered as:
bsub -n 10 -R "span[ptile=5]" pam -mpi -auto_place a.out
For a complete list of mpirun options and environment variable controls refer to the
SGI
mpirun man page.
Limitations
◆ SBD and MBD take a few seconds to get the process IDs and process group IDs
of the PAM jobs from the SGI MPI components, If you use
bstop, bresume, or
bkill before this happens, uncontrolled MPI child processes may be left running.
◆ A single MPI job cannot run on a heterogeneous architecture. The entire job must
run on systems of a single architecture.
