How get MPI Trace data on CLI

  1. How to get MPI trace data for MPI APIs such as Call count, Size of data transferred, MPI time (min, max, and avg)
  2. How to generate Cummulative report

We have added collecting more information to MPI trace with the last release 2022.1. However that data is not yet available in the sqlite for post-run data mining. That should come in the next release or two.

May I ask specifically what you would like to see in a cumulative report? That will help us choose a common subset if we want to write a rule for “nsys stats”.

  • sum count of the instance of each individual MPI event and a sum of min, max & avg time too
