-This example shows how to block on the completion of a set of communications.
-
-As for the other asynchronous examples, the sender initiate all the messages it wants to send and
-pack the resulting simgrid.Comm objects in a list. All messages thus occur concurrently.
-
-The sender then blocks until all ongoing communication terminate, using simgrid.Comm.wait_all()
