I was hoping someone could help me with the following situation. I have a
program which has no MPI support that I'd like to run "in parallel" by
running a portion of my total task on N CPUs of a PBS/Maui/Open-MPI
cluster. (The algorithm is such that there is no real need for MPI, I am
just as well-off running N processes on N CPUs as I would be adding MPI
support to my program and then running on N CPUs.)
So it's easy enough to set up a Perl script to submit N jobs to the queue to
run on N nodes. But, my cluster has two CPUs per node, and I am not
RAM-limited, so I'd like to run two serial jobs per node, one on each node
CPU. From what my admin tells me, I must use the mpiexec command to run my
program so that the scheduler knows to run my program on the nodes which it
has assigned to me.
In my PBS script (this is one of N/2 similar scripts),
#!/bin/bash
#PBS -l nodes=1:ppn=2
#PBS -l walltime=1:00:00:00
mpiexec -pernode program-executable<inputfile1>outputfile1
mpiexec -pernode program-executable<inputfile2>outputfile2
Hi,
To run two serial programs on one dual-cpu node, try
#!/bin/bash
#PBS -l nodes=1:ppn=2
#PBS -l walltime=1:00:00:00
program-executable<inputfile1>outputfile1 &
program-executable<inputfile2>outputfile2
wait
