My timing results are reproducible. As expected, there is no difference
between ./executable and mpirun -n 1 ./executable.

Hi,
I'm fine tuning a simulation in the frequency domain (similar to
https://github.com/dealii/dealii/pull/6747). Because it is in the frequency
domain I can parallelize:
1. Using MPI
2. Running several simulations in parallel for different independent
frequency ranges.
3. A combin
