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;
}
