This requires the idiomatic and platform independent implementation of 2D
graphics and 3D graphics, window management as well as audio output. By using
SDL2 we also ensure that porting to mobile platforms will be easier.

A possible source of problems is that MPI libraries often differ slightly. For
the start it will be good enough to just support one of the popular MPI
libraries like OpenMPI or MPICH. Afterwards it will be interesting how to deal
with the C preprocessor macros specifying the differences between MPI
implementations. You will need to investigate whether a solution such as [in
Julia](https://github.com/lcw/MPI.jl/blob/master/deps/make_f_const.f) will be
necessary to create a custom wrapper for each MPI implementation. Preferrably
this would be solved directly with Nim's capabilities, and the close relation
to C could come in handy here.
