I had also had trouble installing gmx (paralley). But now, its solved.
I would suggest you to see that the mpi is running or not.
Here is a sample mpi C program:
####################################################
#include <stdio.h>
#include "mpi.h"
int main( argc, argv )
int argc;
char **argv;
{
int rank, size;
MPI_Init( &argc, &argv );
MPI_Comm_size( MPI_COMM_WORLD, &size );
MPI_Comm_rank( MPI_COMM_WORLD, &rank );
printf( "Hello world from process %d of %d\n", rank, size );
MPI_Finalize();
return 0;
}
########################################################
save as mpitest.c
compile mpitest.c
mpirun -np 2 -machilefile mac a.out
If every thing is ok. Then the output will be :
Hello world from process
