Subject: Re: [OMPI users] Problems building Open MPI 1.4.1 with Pathscale

It does work with version 1.4. This is the hello world that hangs with

#include <stdio.h>
#include <mpi.h>

int main(int argc, char **argv)
  int node, size;

  MPI_Comm_rank(MPI_COMM_WORLD, &node);
  MPI_Comm_size(MPI_COMM_WORLD, &size);
  printf("Hello World from Node %d of %d.\n", node, size);

  return 0;
