  Dear all, I wrote a 'hello world' program that utilizing mpi. The code is:

  #include "stdio.h"
  #include "mpi.h"
  
  int main(int argc, char *argv[]) {
       int myid, numprocs;
  
      MPI_Init(&argc,&argv);
       MPI_Comm_rank(MPI_COMM_WORLD, &myid);
       MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
  
      printf("%d Hello world from process %d \n",numprocs, myid);
  
      MPI_Finalize();
       return 0;
  }
  

  
  

  I can run this program on a windows server 2012 r2 platform (I also installed headnode of HPC on this computer). However, when I try to run this program on another windows server 2012 r2 platform, the program crashes. It says the '.exe' has stopped working. The error log is that:

  PS C:\Users\Administrator.HPCDWM> mpiexec -n 2 C:\Users\Administrator.HPCDWM\Desktop\MS_MPI_HelloWorld.exe
  
  job aborted:
  [ranks] message
  
  [0] process exited without calling finalize
  
  [1] terminated
