To perform manual MPI timing (hardcoded into the modified Schwimmbad library in the ADACS branch), add the argument `--mpi-timing 1`, which will give a printout at the end of the run in the log file. To record MPI timings at regular 60 seconds intervals, add `--mpi-timing-interval 60`.
Note: The MPI timing printout at the end of the run is a sum of all worker tasks, while the periodic timing intervals are only the timings for **one** worker task. This is to prevent necessary MPI communication during the run.
Using excessively short intervals will result in large overheads. The timing results for each interval are saved in a JSON file `mpi_worker_timing.json` at the end of the run.
## Modifications to the Schwimmbad library
There is some misunderstanding of how the library should be called. The Schwimmbad documentation itself contains incorrect instructions.
