Too much warning sin openmpi

user · December 6, 2009, 6:55am

Hi,

I need to run some programs with MPI, and I installed openmpi in my machine. However I got tons of warning even for a simple hello world program. It complains about lack of libraries which I have already installed. I’m not sure of why. Can anyone help me to take a look at it?

Thanks a lot!

=======Code ===========
#include “mpi.h”
#include <stdio.h>

int main( argc, argv )
int argc;
char **argv;
{
MPI_Init( &argc, &argv );
printf( "Hello world
" );
MPI_Finalize();
return 0;
}

Run “cat /etc/dat.conf”. This is dapl configuration file.

If you have IB cards then execute “mpirun -np 1 --mca btl sm,openib,self a.out”. Otherwise, execute “mpirun -np 1 --mca btl sm,self”.

sm - shared memory
openib - DAPL-capable fabric (over IB cards)
tcp - socket communication (over Eth card)

For example, sm,openib,self: shared memory is used for intranode communications and DAPL fabric is used for internode communications.
