This is the simple MPI program (test.c) I was talking about:
#include <mpi.h>
#include <stdio.h>
int main(int argc, char* argv[]) {
int my_rank; /* rank of process */
int p; /* number of processes */
/* start up MPI */
MPI_Init(&argc, &argv);
/* find out process rank */
MPI_Comm_rank(MPI_COMM_WORLD, &my_rank);
/* find out number of processes */
MPI_Comm_size(MPI_COMM_WORLD, &p);
printf("Hello MPI World! Num processes: %d\n", p);
/* shut down MPI */
MPI_Finalize();
return 0;
}
Issued commands:
$ mpicc test.c
$ orterun -np 4 a.exe
Everything compiles ok.
The second command doesn't work as expected on either open-mpi-1.7.4-1 or
open-mpi-1.7.5-1.
Under openmpi-1.7.4-1 the output for the second command is (and the program
hangs):

Under openmpi-1.7.5-1 the output for the second command is (and the program
exists):
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
orterun detected that one or more processes exited with non-zero status, thus
ca using
the job to be terminated. The first process to do so was:
Process name: [[33371,1],1]
Exit code: 65

1.7.5 will be uploaded shortly.
I don't plan to upload 1.8 until 1.8.1,
but I will built it just to check.

which errors ?
1.8 should be almost identical to 1.7.5, except the oshmem default,
so unlike to make any difference
