Dear Open MPI developers,
We (as in the Debian maintainer for Open MPI) got this bug report from
Uwe who sees mpi apps segfault on Debian systems with the FreeBSD
kernel. Is there anybody here familiar with any BSD peculiarties that
may play a role?
Any input would be greatly appreciated!
Hi Dirk
have you tried using an int instead of unsigned int for rank?
regards, Bettina
Dirk

Hi,
openmpi segfaults on kFreeBSD, I'm not sure where the problem lies.
My openmpi is built from source on i386 kFreeBSD using the patch from
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435573
$ cat a.c
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[])
{
unsigned int rank;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
printf("Hello world, I'm process %d\n", rank);
MPI_Finalize();
}
$ mpicc a.c
$ mpirun -np 1 ./a.out
