Agenda

Present:

Apologies:

MacOS Installation issues (UPDATE)

JB: I still don't like the MacOS platform

• Apparently can't downgrade CLT to 14.3.1 on latest MacOS Samoa. (I can't find official link, haven't actually tried, been working on a fix).
• MPICH built by PETSc with CLT 15 is broken, it requires additional LDFLAGS (-Wl,-ld_classic) to configure. (PETSc need to fix this)
• Firedrake install script is in a bit of a state, don't fix by setting export PETSC_CONFIGURE_OPTIONS=--LDFLAGS=-Wl,-ld_classic that will break your BLAS configuration.
• Potential fix, but needs more extensive testing: PR3171.
  • MERGED. Hopefully a fix!

FML

JB: Documentation needs some policy decisions #3041.

• Close to merging

RNH: Thoughts on #3167

Also, why does Cofunction not have a .zero method?

• Needs annotation added
• RNH's PR needs the fix to be specific to the case he has identified - i.e. within the SFreduce.

Merge PRs

• JB: #3153 Github PR template. MERGED!
• JB: #3165 MERGED!
• JB: #1 MERGED! Q: Do we need protection on this repo? A: No.
• UZ: #3176 Netgen circular import MERGED!
• UZ: Netgen Hierarchy Stuff Won't effect us since we use netgen wheels. UZ to make a PR with them. For now merged to our fork so it can be used by those who want it and don't mind having to build it themselves.
• PB: #3148 Fix prolong/restrict on extruded. MERGED!
• PB: #3159 Cache/no-op for prolong/restrict/inject. Needs checking for dual space safety.
