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.
MPI_THREAD_MULTIPLE is unlikely to work at all (regardless of network)
in the v1.2 series.

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.

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

Just a quick question...

I have a user who specified MVAPICH2 as he needs some features like
extra task spawning, but I am trying to standardize on Open MPI compiled
against Infiniband for my primary software stack
