- Pick Chair and Minuter (KS to pick minuter)
- ALL: (ongoing) triage the open issues and confirm if they are indeed still open (and perhaps provide labels)
- DH: Organise Firedrake 2022 (Registration deadline approaching, events apart from talks?, see discussion below)
- ALL: Rename split (
.split
->.subfunctions
) (ongoing - issue created) - JB: A Firedrake manual (ongoing)
- JB: Python 3.11 (ongoing)
- All: Go through TSFC PRs
- RNH: check if issue #2516 is still a problem, if yes, see if #2509 Try installing pre-release of VTK from PyPI (supporting Python 3.10) fixes (done)
- JB: Move PyOP2 and FInAT to firedrakeproject (ongoing)
- ALL: do things with SV's branches
Present: DH, JB, KS, JHC, RNH, DRS, PK, CW (minuter), NB
Apologies:
- DH: There are train strikes over this week. DH will look into chartering a coach from Imperial to Totnes via Reading, M4 (for Oxford) and possibly Exeter.
- DH: We might have time for extra events that aren't talks. Maybe general discussion, maybe clinic. DH could also do a longer-form presentation on, for example, how the adjoint works.
- DRS: Pickling of UFL elements broken somewhere.
- KS: Could possibly use
__repr__
. - DH: Simplest case is variant, degree, cell.
__repr__
might not be sufficient. - Action point: KS to fix serialisation of elements.
- Action point: DRS to talk to Angus Gibson about interface changes between ROL v1 and ROL v2. Also consider switching to v2.
The code associated with PYOP2_NO_FORK_AVAILABLE
is not tested and is broken
(okay I broke it, but it's broken beyond this!! ie: loopy forks, maybe other dependencies too).
I think I know why this exists, but is anyone using it, is it still worth maintaining and testing?
- DH: Realistically all clusters are Linux and no users have hit this. Dropping it is probably safe.
- Action point: JB go ahead and expunge.
- JHC: Additional MPI methods for Ensemble #2639 - reviewed
- CW: Halo freezing: Firedrake and PyOP2 - merged
- JB: GC Fix #2599 been round once before, DEFCON now has a fix, are we ready? - to resolve in separate meeting with DH
- JB: Python 3.11 #2358, is this ready? Mac users? - not yet, homebrew ML bugs etc
