I have recently installed OpenMPI on my computer and when I try to run a simple Hello World program, it exits with the next error:
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
This is the program's source code:
#include <mpi.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
int size, rank;
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &size);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
printf("Hello\n");
MPI_Finalize();
return 0;
}
This is how I compile the program:
mpicc -o hello hello.c
and I execute it with
mpirun -np 2 hello
It throws no errors on compilation, and if I run ./hello
, it runs ok.
Excuse my english, any correction will be welcome.
you have to ./ the executable name try this, mpirun -np 2 ./hello
