Agenda

Present: DH, CW, JB, IM, DD, RK, PB, JHC, KS

Apologies:

GregVernon's PR PR#2116:

real-mode test failed for some reason.

Sophia's PR:

DH: This is not the part of the code that we often touch.

Firedrake US 2025

Friday and Saturday before CSE.## JHC: Docs JHC: PR#3742. By default, Sphinx doesn't build the docs for "special" methods i.e. dunder methods. This PR adds a line to the documentation configuration so that __call__ methods are documented in the API listing.

DH: Uncontroversial.

DD: MUMPS + Mac updates:

• The PETSc make test runs successfully with MUMPS. However, Firedrake tests are still failing when run in parallel.
• petsc4py also fails in parallel when using MUMPS. So, I believe this is not a problem with Firedrake itself but rather with petsc4py. I will continue to investigate this further.

DD: Wrap up MFE and open new issue in upstream.

JB: Caching update

WIP is in PyOP2 and Firedrake PRs, discussion needed?

JB: Centralise all caching in one place (disk or memory cache). Removed CachedObject.

DH: In principle this looks right.

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.

KS: part1: Minor changes required.

DD: FWI demo:
