Agenda

Present: JB, JHC, IM, RK

Apologies: CW

JB: ARCHER2 Capability day is a painful experience

JHC: Agreed!

JB: mpi4py update

PR #3777 will unpin mpi4py==3.1.6, this will be an issue for anyone still running MPI-3 (cough ARCHER2). However, it is believed this is only advanced use cases. mpi4py>4.0 brings us one step closer to wheel. We should transition over to using wheels (for dependencies) bit by bit, rather than all at once.

RK: Demos update

New student will add Irksome to the existing demos.

JB: Possible demos hackathon in the future, watch this space.

RK: Where should ideas for new demos go?

JB: Open an issue

Some ideas discussed:

• Exotic elements
• FML
• PatchPC/ASM
• External operator

Possible documentation sprint for Firedrake?

RK will be in the UK in Spring 2025.

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.

• #3778 Remove ML frameworks from vanilla container. Merged
• #3725 Fix ensemble tests. Changes applied.
