Agenda

Present: DH, DID, JB, CW, NB, FA, IM, JHC, KS

Apologies:

JB: PDESoft in Cambridge

Info + registration at this link

Required for SysgenX.

Happening in July.

ALL: submit abstract.

JB: Make VTK a soft dependency

https://github.com/firedrakeproject/firedrake/pull/3324

VTK wheels are not available on some platforms.

DH: netcdf is like HDF5, so it itself is not required by Firedrake, but by Gusto.

JB: Move checkpointing.py to output folder.

JB: Progress on RTree

PR closer to being merged. See libsupermesh and firedrake PRs for progress on our side.

JB: continue working with the firedrake branch.

CW: Status of "backend" for adjoint

See relevant issue. Surely "backend" is a redundant concept now?

Yes. Someone needs to replace all backend with whatever.

expunge vectors in adjoint -> use Cofunctions.

expunge Function.vector -> suggest using PETSc.vec or dat.data.

JB: Firedrake team

Add Daiane to "Active" and move Sophia to "Former". We should make sure we are not forgetting anyone else either!

DID: Do this adding her own photo.

NB: Interp

• Firedrake PR

• Pyadjoint PR

Documentation is failing.

DH: probably just take "optional" out?

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.

JB: #3152 Firedrake public interface to GC + PyOP2#712 this has been reviewed and iterated several times.
