mpiCheckPhaseHook

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

Example:

  { mpiCheckPhaseHook, mpi, ... }:
  {
    # ...

    nativeCheckInputs = [
      openssh
      mpiCheckPhaseHook
    ];
  }
