Subject: [OMPI users] Mpirun --app option not working
From: Sindhi, Waris PW (Waris.Sindhi_at_[hidden])
Date: 2011-02-09 11:32:50


Hi,
    I am having trouble using the --app option with OpenMPI's mpirun
command. The MPI processes launched with the --app option get launched
on the linux node that mpirun command is executed on.

The same MPI executable works when specified on the command line using
the -np <num-procs> option.

Please let me know what I am doing wrong ?

Bad launch :

head-node % /usr/lib64/openmpi/1.4-gcc/bin/mpirun --host
node1,node1,node2,node2 --app appfile
head-node :Hello world from 0
head-node :Hello world from 3
head-node :Hello world from 1
head-node :Hello world from 2

Good launch :

head-node % /usr/lib64/openmpi/1.4-gcc/bin/mpirun --host
node1,node1,node2,node2 -np 4 mpiinit
node1 :Hello world from 0
node2 :Hello world from 2
node2 :Hello world from 3
node1 :Hello world from 1

head-node % cat appfile
-np 1 /home/user461/OPENMPI/mpiinit
-np 1 /home/user461/OPENMPI/mpiinit
-np 1 /home/user461/OPENMPI/mpiinit
-np 1 /home/user461/OPENMPI/mpiinit

head-node % cat mpiinit.c
#include <mpi.h>
#include <stdio.h>

int main(int argc, char** argv)
{
    int rc, me;
    char pname[MPI_MAX_PROCESSOR_NAME];
    int plen;

    MPI_Init(
       &argc,
       &argv
    );

    rc = MPI_Comm_rank(
            MPI_COMM_WORLD,
            &me
    );

    if (rc != MPI_SUCCESS)
    {
       return rc;
    }

    MPI_Get_processor_name(
       pname,
       &plen
    );

    printf("%s:Hello world from %d\n", pname, me);

    MPI_Finalize();

    return 0;
}
