Agenda

Present:

Apologies: UZ

pyadjoint PR#177

Allow set_working_tape and stop_annotating to be used as function decorators, and implement no_annotations in terms of stop_annotating.

CW: Merging JB's big merge

https://github.com/firedrakeproject/firedrake/pull/3817 is very nearly ready I believe. I am keen to get it merged ASAP as it is holding up any changes to PyOP2.

CW: (related) What is the long-term vision for Firedrake installation?

• I believe that we want to be moving towards pip install firedrake (even without a wheel) as the sole installation method.
• firedrake-install should be made much more minimal, effectively building PETSc and then called pip install firedrake. Importantly this means:
  • The script should not manage homebrew or apt
  • Extra packages like pytorch, gusto etc should not be installed via special flags. They can just be pip-installed.

Thoughts? If people agree then I can work to rip out a lot of code and incrementally improve the installation process.

PB: RestrictedFunctionSpace

Ongoing discussion on what is the right interface to restrict any FunctionSpace given the bcs of a problem.

My proposal: RestrictedFunctionSpace(MixedFunctionSpace, bcs)

PR needs review

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.

1. UZ: ngsPETSc was not installed via pip PR#3873

2. DD: Disk checkpointing for adjoints with schedules: Firedrake PR 3812 + Pyadjoint PR 173

3. KS: dtype
