   Because there are separate send and receive types to alltoallw,
   there need to be tests to rearrange data on the fly.  Not done yet.

   The first test sends i items to processor i from all processors.
 
   Currently, the test uses only MPI_INT; this is adequate for testing systems
   that use point-to-point operations
