MPI has nothing to do with threads. It is designed primarily for distributed
environments, therefore it deals with processes living in separate address
spaces. You can create threads (using Pthreads routines) within an MPI
process on your own risk. However, if you call MPI routines concurrently
from many threads, you are not guaranteed correct results (most current MPI
implementations are not thread safe). For more information, see chapter
"8.7. MPI and Threads" in MPI 2.0 specification. If you are interested in
thread-based programming on SMP systems, see OpenMP (www.openmp.org).
