Re: [ptp-user] Program Arguments

[Jonathan Chu <jrchu@xxxxxxx>]

I think I see the same thing. I augmented the sample Hello World MPI 
example to print out the arguments:

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

int main(int argc, char *argv[]) {
   int rank;
   MPI_Init(&argc, &argv);
   MPI_Comm_rank(MPI_COMM_WORLD, &rank);
   printf("ArgC: %d\n",argc);
   printf("Argv: %d %d\n", atoi(argv[0]),atoi(argv[1]) );
   printf("Hello World from rank=%d\n", rank);
   MPI_Finalize();
   return 0;
}

I then added command line arguments to the program in the run 
configuration under the Arguments tab in the Parallel program arguments 
with the values 500 1024 215432543.

My output was:

ArgC: 2
Argv: 0 500
Hello World from rank=0
