Research direction

The issue names no files, tests, or entry points. Start by examining mpiP's existing profiler output and report-generation paths to determine whether rank-to-rank byte totals are already collected. Done would require a defined communication-matrix output and a way to verify its values, neither of which the issue currently specifies.

Written by the indexing model from the issue text.
