In this measurement we use the MPI_Waitsome-routine to coordinate the incoming worker
messages. This function guaranties a fair coordination of the workers,
because every sending worker will be received.
Here ist is varied over the number of workers.
Pattern: Master-Worker varied over number of nodes.
default values: 8 nodes, message length 256 units, chunks 10, max. / act. time for suite disabled/0.00 min.
