[Beowulf] Using Autoparallel compilers or Multi-Threaded libraries with MPI

Many problems decompose well in large chunks that are well done
with MPI on different nodes, and tight loops that are best done
locally with shared memory processors.  In such problems one can
use both types of parallelisms well.  My understanding of non-thread
safe MPI is that one should avoid having MPI commands within OpenMP
optimized chunk of code, but the contrary is allowed.
