I just write a simple MPI programs:

#include "stdio.h"
#include "stdlib.h"
#include "mpi.h"

int main(int argc, char *argv[])
{
int rank,nProcs,ierr;

MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &nProcs);

if (rank == 1)
printf("Hello world");

MPI_Finalize();

return 1;
}

No wrong in compile, however, it runs wrong:


problem with execution of a.out on dhcp184: [Errno 2] No such file or directory
problem with execution of a.out on dhcp184: [Errno 2] No such file or directory

What's the problem????

run a debugger,

compile with:
so what line is causing it. never used any MPI stuff so i can't really help you out. But good luck

thanks,
