Present:

Apologies:

CW: What is the data representation of a MixedDat?

From this issue it is suggested that the data part of a MixedDat is just the concatenation of several Dats. So a MixedDat containing 3 Dats of length n and dim=3 would have shape (3, n, 3). How does this work if the Dats have different dims?

CW: Proposal: A new type system for PyOP2

See here. This has now likely been superceded by https://github.com/OP2/PyOP2/pull/624#issuecomment-896047790.

CW: What belongs in the Firedrake wiki?

We have written a guide to profiling Firedrake with LIKWID and put it in the Firedrake wiki. Does it belong here or should it be put on the website?

Merge PRs:

SV: Can we merge #2111, please? :)

CW: Also https://github.com/OP2/PyOP2/pull/630
