You need to call MPI_Init before calling any other MPI-functions.
Add that line and you should be up and running :-)
-----------------------------------------
#include <stdio.h>
#include "mpi.h"
int main (int argc, char **argv) {
int myId,p;
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &p);
MPI_Comm_rank(MPI_COMM_WORLD, &myId);
printf("Hello World.... from processes %d \n", myId);
MPI_Finalize();
return 0;
}
