Detailed Description

Synchronization statistics.

When the before/after synchronization comparison is active, each rank knows for its part whether the compared values are the same or not.

However, a reduction must be performed over all ranks to have a global view of the comparison (because only one rank for which the comparison is different is sufficient to consider the comparison to be different).

Since it is too costly to perform the reduction for every synchronization, we maintain a list of comparisons and process this list when it reaches a certain size or if it is explicitly requested.
