Haha, yeah we found out about that one when trying to run Linpack with
threaded BLAS implementations.
On the MPI-2 note, anyone running MATLAB and the parallel toolkit under
Open MPI? They are unreasonably obscure about what MPI they need
although I do believe they need MPI-2 functions.
If it will work with Open MPI, and is not a nightmare to set up, I may
try it as some of my users would be elated. If there are excessive
problems, I may opt for SciLab which is supposed to be an "equivalent"
and open source.

One small (or to some, not so small) note is that full multi-threading
with OpenMPI is very unlikely to work with infiniband right now.

Quick answer, till you get a complete answer, Yes, OpenMPI has long
supported most of the MPI-2 features.
