Sorry for the late reply.
Basically, any MPI application will do.
Bah, I should have been more precise in this:
not just any old tests/benchmarks but
recommended, reliable tests/benchmarks?

Are there any recommended tests/benchmarks for the heterogenous
installations? I'd like to have something measuring the throughput of
lengthy computations, which would be executed on the installation with
the heterogenous nodes.
Thanks.

In general, you need both OMPI and your application compiled natively
for each platform. One easy way to do this is to install Open MPI
locally on each node in the same filesystem location (e.g.,
/opt/openmpi-). You also want exactly the same version of
Open MPI on a

I'm not quite sure what an MP-MPICH meta host is.
Open MPI allows you to specify multiple hosts in a hostfile and run a
single MPI job across all of them, assuming they're connected by at
least some common TCP network.
What I need is one MPI job put for distributed

Can't find this in FAQ... Can I create the metahost in OpenMPI (a la
MP-MPICH), to execute the MPI application simultaneously on several
physically different machines connected by TCP/IP?
