pamOptions for vendor MPI jobs-auto_place-mpiThe -auto_place option on the pam command line tells the SGI IRIX mpirun library tolaunch the MPI application according to the resources allocated by LSF.In the SGI environment, the -mpi option on the bsub and pam command line isequivalent to the mpirun command.On HP-UX, you can have LSF manage the allocation of hosts to achieve better resourceutilization by coordinating the start-up phase with mpirun. This is done by precedingthe regular HP MPI mpirun command with:bsub pam -mpiFor HP-UX vendor MPI jobs, the -mpi option must be the first option of the pamcommand.For example, to run a single-host job and have LSF select the host, the command:mpirun -np 14 a.outis entered as:bsub pam -mpi mpirun -np 14 a.out-n num_tasksThe number of processors required to run the parallel application, typically the sameas the number of parallel tasks in the job. If the host is a multiprocessor, one host canstart several tasks.You can use both bsub -n and pam -n in the same job submission. The numberspecified in the pam -n option should be less than or equal to the number specified bybsub -n. If the number of tasks specified with pam -n is greater than the numberspecified by bsub -n, the pam -n is ignored.For example, on SGI IRIX or SGI Altix, you can specify:mpi_app [argument ...]-h-Vbsub -n 5 pam -n 2 -mpi -auto_place a.outHere, the job requests 5 processors, but PAM only starts 2 parallel tasks.The name of the MPI application to be run on the listed hosts. This must be the lastargument on the command line.Prints command usage to stderr and exit.Prints LSF release version to stderr and exit.320 Platform LSF Command Reference
