Enumeration Type Documentation

enum boost::mpi::threading::level

specify the supported threading level.

Based on MPI 2 standard/8.7.3

Enumerator
single	Only one thread will execute.
funneled	Only main thread will do MPI calls. The process may be multi-threaded, but only the main thread will make MPI calls (all MPI calls are ``funneled'' to the main thread).
serialized	Only one thread at the time do MPI calls. The process may be multi-threaded, and multiple threads may make MPI calls, but only one at a time: MPI calls are not made concurrently from two distinct threads (all MPI calls are ``serialized'').
multiple	Multiple thread may do MPI calls. Multiple threads may call MPI, with no restrictions.
