Detailed Description

Optimized implementation for MPI synchronization.

This class implements the historical version of synchronization that exists in Arcane versions prior to 3.2.

Compared to the base version, this implementation uses MPI_Waitsome (instead of Waitall) and copies into the destination buffer as soon as a message arrives.
