mpiCheckPhaseHook {#setup-hook-mpi-check}#

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

Example:

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

  nativeCheckInputs = [
    openssh
    mpiCheckPhaseHook
  ];
}
