  Hello, 

  I have been trying to implement mpi example by c++ on visual studio for several hours, but every time it fails, I tried two examples I will attach a screenshot of one of them, the example is from a youtube video it succeeded in the video also I followed a tutorial to do that but it failed, please help!

  Thanks.

  I couldn't attach a screenshot so that is the code instead:

  #include "mpi.h"
  #include "stdafx.h"
  #include <string>
  #include <stdio.h>

  int main(int *argc, char **argv)
  {
   int commsize;
   int rank;

   MPI_Init(NULL, NULL);
   MPI_Comm_rank(MPI_COMM_WORLD, &rank);
   MPI_Comm_size(MPI_COMM_WORLD, &commsize);
   printf("Hello MPI");
   MPI_Finalize();
   return 0;
  }
