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 Chandan -- Chandan kumar Choudhury NCL, Pune INDIA On Sat, Feb 6, 2010 at 5:47 AM, Jussi Lehtola <jussi.leht...@helsinki.fi>wrote: > On Fri, 2010-02-05 at 15:29 -0500, Matthew L.
