Hi,
(Greetings from the BSP at TU-Dresden, 2016!)
Updating mpirun-bin from 1.10.2-14 to 2.0.1-7 breaks the testsuite
of dune-common (error below), but also this simple testcase too:
| #include <mpi.h>
|
| int main(int argc, char *argv[]) {
| MPI_Init(&argc, &argv);
| MPI_Finalize();
| return 0;
| }
fails with:
> $ OMPI_MCA_plm_rsh_agent=/bin/false ./testcase

It is the same error in dune-common:

What I understand so far is that, since MPI version 2.x, pmix_native.c
tries to check peer credentials on a socket. But FreeBSD lacks
SO_PEERCRED and there isn't yet code to implement this any other way.
FreeBSD ports hasn't packed MPI version 2.x yet so, probably this
is just unimplemented/unported yet.
