  • Question

  • If not - then tell me which distribution of MPI should I use instead, since https://www.mpich.org/downloads/ does not provide any alternatives for Windows.

    I am very frustrated after a whole week of trying everything imaginable and unimaginable, it seems that your SDK is missing something:
