Sorry for the problem - the issue is a bug in the handling of the pernode
option in 1.4.2. This has been fixed and awaits release in 1.4.3.

Hello,
I'm using OpenMPI 1.4.2 on a Rocks 5.2 cluster. I compiled it on my
own to have a thread-enabled MPI (the OMPI coming with Rocks 5.2
apparently only supports MPI_THREAD_SINGLE), and installed into ~/sw.
To test the newly installed library I compiled a simple "hello world"
that comes with

I just want to comment that Open MPI's opaque (to the user) pointers are
significantly better than int because it offers type safety. That is,

This is the error you get when an invalid communicator handle is passed
to a MPI function, the handle is deferenced so you may or may not get a
SEGV from it depending on the value you pass.
The 0x44a0 address is an offset from 0x4400, the value of
MPI_COMM_WORLD in mpich2, my guess would

Hi
Are you also sure that you have the same version of Open-MPI
on every machine of your cluster, and that it is the mpicxx of this
version that is called when you run your program?
I ask because you mentioned that there was an old version of Open-MPI
present... die you remove this?

Hi,
I'm running an mpi module in python (pypar), but I believe (after
googling) that this might be a problem with openmpi.
When I run: 'python -c "import pypar"', I get:
