Minutes

Present: DH, JB, CC, RK, JHC, SV, CW, KS

Apologies:

CC: Multigrid on Emmersed manifold

CC: Has ManifoldTransfer class to move coordinates. Can we merge this into Firedrake?

DH: Rather than writing those details, instantiate TransfreManager(TM) and stash things; this way it is more self-contained in the TM at least.

CC: Make a PR.

JB: Relevant? https://github.com/firedrakeproject/firedrake/issues/2185

https://github.com/firedrakeproject/firedrake/wiki/Firedrake-meeting-2021-08-18#rnhjb-mesh-dmcoordinates-field-disconnect

CC: Time parallel checkpoininting

DH:

• 1st option. Just open HDF5 file with "COMM_WORLD" and write from subcommunicator.
• 2nd option. Schedule who has got file open and one subcomm writes at a time using "-a".

Merge PRs
