This hook can be used to setup a check phase that requires running a MPI application. It detects the used present MPI implementaion type and exports the neceesary environment variables to use mpirun and mpiexec in a Nix sandbox.

Example:

  { mpiCheckPhaseHook, mpi, ... }:

  ...

  nativeCheckInputs = [
    openssh
    mpiCheckPhaseHook
  ];
