MPI problem with mpirun, using mpicc and simple hellworld program.

Question

analog to my stackoverflow post I need help with mpi. I am using openmpi and this is my sourcecode:
#include <stdio.h>
#include <mpi.h>
main (int argc, char* argv[]) {
int myrank;
int size;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
printf("Hello World. I'm process %d of %d processes.", myrank, size);
MPI_Finalize();
return 0;
If I now do:
mpicc test.c -o test
this works fine, but
mpirun -np 2 test
I get the error:
mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.
What could be the reason for this problem???
What can I do now?
Do you need further information?
