Description

In mpich 3.4.3 PLMPISlaveProgressionManager::IsInterruptionRequested() takes 2 orders of magnitude longer than in mpich 4.1.1. This is due the two calls to MPI_IProbe within the method.

The idea is to investigate if it is possible reprogram the method to avoid the delay whatever version of mpich.
