Notices

1. Firedrake User Meeting 16-18 September 2024 Firedrake (Registration 25th August/Abstracts 18th August)

Minutes

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

Apologies: NB

DH:

• Everyone that will present in PDESoft please add the Firedrake 2024 advertisement.
• DH, NB, and Nickolas will present a Firedrake tutorial in South Africa.

JHC: I would like PETSc branch updating but it's dependent on #3546

CW: How do we solve this issue?

DH: This looks like a mistake in UFL. The geometry lowering test uses the embedded_superdegre but should be embedded_subdegree.

JB: Ensemble is broken

And may have been for some time 😳

Sometimes the parallel decomposition is not the same.

DH: SPMD is not very robust. Relying that all ranks are doing the same calculation is not robust. Perhaps this thing is happening in CI and not for the user cases.

JB: Numpy 2.0 is out

(this is in PRs below, but might be worth discussing in detail)

JB: If you type pip install numpy, the version will be 2.0. We may no longer install numpy from scratch.
