-/*
-   This program tests MPI_Alltoallv by having processor i send different
-   amounts of data to each processor.
-
-   Because there are separate send and receive types to alltoallv,
-   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
