Haha, yeah we found out about that one when trying to run Linpack with
threaded BLAS implementations.
BTW Goto BLAS threaded implementation doesn't use any MPI calls. So you
may build Linpack with Goto_thread + OMPI non-threaded and it will run
without any problem.
Pasha.
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.
