MPI

[Alex Merritt]

Hello,

Has anyone successfully been able to execute an MPI program? I have tried
with both mpich and mpich2 from the pkg library on DF 4.0.6:

// mpicc mpitest.c -o mpitest
#include <mpi.h>
int main(int narg, char **arg) {
        int me,nprocs;
        MPI_Init(&narg,&arg);
        MPI_Comm_rank(MPI_COMM_WORLD,&me);
        MPI_Comm_size(MPI_COMM_WORLD,&nprocs);
        MPI_Finalize();
        return 0;
}

With mpich2 1.5_2,5

% ./mpitest
Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(420)..............:
MPID_Init(180).....................: channel initialization failed
MPIDI_CH3_Init(38).................:

% mpirun -np 1 ./mpitest
mpiexec failed: gethostbyname_ex failed for

With mpich 3.1.4_1
