Minutes

Present: CW (minuter), SM, RK, PB, IM, KS, DD, DH

Apologies: JHC

RCK: Firedrake USA'25

• I have a PR with the Web page that's approved, but it's failing CI tests for seemingly unrelated things like PyOP2 and TSFC.

• Update: we have a travel support request form, are waiting on a business office person to give us a registration link.

• Merged.

CW: Testing strategy

Someone just reported that Firedrake fails with an int64 build. Since we don't test it we didn't notice. My proposal:

• We should have a set of smoke tests that target a large surface where we encounter issues (e.g. libsupermesh, VoM, parallel, ...). This should take ~5 minutes to run (and we can even call it make check).

• We can run a larger number of possible Firedrake configurations whenever we merge to master (e.g. int64, OpenMPI?, etc). We can also run them if we apply a sensible label like we do for MacOS (ci:macOS, ci:int64, etc). Using pip it only takes about 30 minutes for a workflow to run.

• DH: Tentative approval.

• Action point CW make this happen.

Merge PRs

Note that PRs put in this section should either be trivial or already have been reviewed. Discussion-worthy PRs should be separate agenda items.

RCK: Firedrake conference

• Merged.

KS:restricted function space with extrusion

• Merged

DD: Enable measure options for Riesz representation

• This would be better exposed via form_compiler_parameters. PR is not required.

DD: Ensemble reduced functional arguments

• Merged.

DD: Document the Reduced functional args (pyadjoint)

• Merged.

DD: Options for Riesz represention solver (pyadjoint)

• DD to revisit in light of #3911 feedback.
