[OMPI users] MPI_Test without deallocation

[Shaun Jackman]

Is there a function similar to MPI_Test that doesn't deallocate the 
MPI_Request object? I would like to test if a message has been 
received (MPI_Irecv), check its tag, and dispatch the MPI_Request to 
another function based on that tag.

Cheers,
Shaun
