New MPI Library on the cluster

Since WSU’s Grid had an upgrade of its operating system recently, we need to use a new MPI Library to compile and run our Jobs.

1

How to compile your program

First, we need to run “qsub –I” command.Second, load the new mpi module by the next two commands:

module load pgi-14.6/compilermodule load pgi-14.6/compiler-mpi

Third, use mpicc command to compile your program as before

The new script to submit jobs

#!/bin/bash

#PBS -l ncpus=8#PBS -l nodes=4:ppn=2#PBS -m ea#PBS -q mtxq#PBS -o grid.wayne.edu:~fb4032/tmp3/new3#PBS -e grid.wayne.edu:~fb4032/tmp3/new4module load pgi-14.6/compilermodule load pgi-14.6/compiler-mpi/wsu/apps/compilers/pgi/pgicdk-146/linux86-64/2014/mpi/mpich/bin/mpiexec \-machinefile $PBS_NODEFILE \-n 8 \/wsu/home/fb/fb40/fb4032/hello

The commands in red are the modifications, and you should just run “qsub job.sh” to submit jobs as before.
