Subject: [OMPI users] can not get hello.cpp to run...
From: Jonathan Bishop (jbishop.rwc_at_[hidden])

Hi,

New to MPI and decided to try OpenMPI out on hello.cpp, but I get the
following messages and the program hangs…

MPICH had no problem with this…what am I doing wrong?

Thanks,

Jon

Here is hello.cpp

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

using namespace std;

int main(int argc, char *argv[]) {
  int numprocs, rank, namelen;
  char processor_name[MPI_MAX_PROCESSOR_NAME];

  MPI_Init(&argc, &argv);
  MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
  MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  MPI_Get_processor_name(processor_name, &namelen);

  printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);

  MPI_Finalize();
}

And here is the output I got…
