[MPICH] Multithreading on Windows

[Yoder, Jeffrey - SSD]

We are using MPI_THREAD_MULTIPLE on Windows and seem to be having some
success but also some troubles which we are thinking might be related to
the threading on Windows.

 

I know MPI_THREAD_MULTIPLE is only a request and, in fact,
MPI_Init_thread always returns MPI_THREAD_SINGLE.  But we seem to be
able to operate multi-threaded in some instances.

 

Does this make sense?  Why would it work sometimes and not others?
Should we dump the Windows platform altogether?
