How well does MPI work?
The short answer is pretty well on Linux and OSX and not so well on Windows. MPI was originally developed on UNIX, so this is not a surprise (and it’s a great feat in many ways for it to even run on Windows). The Windows specific quirks we’re seeing are due to MPI-Windows interaction, and we’re trying to hunt them down, as well as try out other MPI possibilities.
