This workaround stage prevents srun from returning 0 to the upper stages
when a signal happens after MPI_Finalize. It writes the return code to a
file named .srun.rc.$rank and later checks that exists and contains a 0.
When the program is killed, exits with non-zero and the error is
propagated to the baywatch stage, which aborts immediately without
creating the rc file.
These targets allow one experiment to directly refer to another
experiment results, thus a dependency chain can be formed to ensure
execution order.
It also simplifies the dataset definition, as they can be automatically
fetched from the experiment directly.
- All garlic stuff is moved into garlic/
- Group the overlay index by sections
- Add a garlic/default.nix link to the main default.nix, so we can
build derivations at garlic/
