Hi Valmor,
What is happening here is that when Open MPI tries to create MX endpoint for
communication, mx returns code 20, which is MX_BUSY.
At this point we should gracefully move on, but there is a bug in Open MPI 1.2
which causes a segmentation fault in case of this type of error. This will
Steve,
This list is for supporting Open MPI, not MPICH2 (MPICH2 is an
entirely different software package). You should probably redirect
your question to their support lists.
Thanks,

Well that's not a good thing. I have filed a bug about this (https://
svn.open-mpi.org/trac/ompi/ticket/954) and will try to look into it
soon, but don't know when it will get fixed.
Thanks for bringing this to our attention!

David,
Have you tried something like
mpirun -np 1 --host talisker4 hostname
If that hangs, try adding '--debug-daemons' to the command line and
see if the output from that helps. If not, please send the output to
the list.
Thanks,

Bala,
This is a known problem with the 1.1 series. The bad news is that I
know of no fix for this, though many people work around this problem
by running a cleanup script after each unclean run. The good news is
that the 1.2 series is MUCH better, though still not perfect. I would

Never mind, I was just able to replicate it. I'll look into it.

Hi Martin,
Yeah, we appear to have some mistakes in the configuration macros. I
will correct them, but they really should not be effecting things in
this instance.
Whether Open MPI expects a 32 bit or 64 bit library depends on the
compiler. If your compiler generates 64 bit executables by
