Agenda

Present: CW (minuter), DH, RNH, JB, DS, KS

Apologies:

DH: Loopy caching issue 2610

• DH: We should have a single FIREDRAKE_CACHE_DIR variable that would set all other cache directories.

RNH: Issue 2595

The UFL update to fenics main made certain things not work any more and is currently breaking Gusto

• DH: We possibly overlooked a case since ReferenceGrad is just linear so we should know how to take a derivative of it.
• DH: TODO comment suggests that it should be doable for the simple case which would fix the current issue.

JB: GC fix landing soon

Need to look over "abuse of comms" PR in PyOP2 and GC fix in Firedrake.

• JB: All PyOP2 objects should now always use an internal communicator.
• DH: Reviewed, small changes requested.

JB: Python 3.11 is here

MacOS users, please create me some VTK wheels! We are still waiting for an mpi4py wheel before this can be merged 🙁.

• JB: Step PyOP2 supported versions too.
• DH: Once MacOS machines are up we will set up a GitHub action to build and publish the wheels we need.

Merge PRs

CW: https://github.com/firedrakeproject/firedrake/pull/2562 and https://github.com/dolfin-adjoint/pyadjoint/pull/93

• DH: FEniCSx doesn't support adjoint any more so compatibility issues not so important.
• DH: More discussion required.
