  Spectral method direct numerical simulations package with mpi support

The report is somewhat in line with my experience. Rayon is ok for a few threads (<50), beyond that the execution time doesn't really scale well anymore unfortunately. This is too little for many HPC applications in fluid simulations. I had a fluid solver once parallelized with MPI and it had more or less optimal scaling for 1000+ processors and was also on par with codes written in C and Fortran, but I didn't compare it 1:1. Here is the mpi code. (It's a bit rough though and certainly not perfect) https://github.com/preiter93/rustpde-mpi
