Update the simfactory entry for Expanse

[Gabriele Bozzola]

I submitted a PR to the simfactory repo to fix a problem with Python and running rpar parameter files.

Can you add the link to the pull request? Since you are the maintainer of the entry, you should also be able just to push the updated entry. Do you have commit rights?

I do not have write access to the repo.

I just invited your University of Arizona email to Simfactoy’s Bitbucket repo so that you can push. Having said that: the commit seems to indicate that “numpy” fails, so you are using numpy in your rpar files?

The pull request also adds a line

OPENBLAS_DIR = /cm/shared/apps/spack/cpu/opt/spack/linux-centos8-zen2/gcc-10.2.0/openblas-0.3.10-3lzjcwjsyu3qmott7k3k52mtzljioax3/

to the option list which seems to go beyond the stated goal of fixing some issue with Python, at least at first glance. Adding it (assuming that this is the correct path for the loaded module) is the correct thing to do, but ideally should be done in a separate commit (no stealth changes with subject lines “whiterabbit.exe” please).

Hi Roland, I didn’t act quickly enough and the invitation expired. Can you send another one?

Yes, that is correct.

NumPy is compiled against OpenBlas, which has to be loaded to correctly use the package. The line ensures that OpenBlas is consistent within the environment (ie, NumPy and Einstein Toolkit use the same OpenBlas, as it is provided by the module). I agree that this a little bit beyond the scope of the commit, also because there is no need for NumPy and Einstein Toolkit to use the same OpenBlas.

In general, following the discussion in the mailing list (http://lists.einsteintoolkit.org/pipermail/users/2021-August/008179.html), it is likely that this entry for Expanse is not the best one. I am waiting to see if the admins do anything about their ucx/verbs stack.

Done.
