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…
