2023.08.10 Meeting Notes

Agenda

• Individual/group updates
• review non-WIP PRs

Individual/group updates

LR

• geometric MG working in 1D incl some test cases
• currently limit to coarsest block (but not coarser)
• looking at removing that restriction and also allow for non-cubic root grid
• has PR up to update indices and region sizes

PM

• fixed (backported) iterative task lists
• PR is up and ready to go
• performance comparison to AthenaK almost ready to go

BP

• PEP 1 PR out of WIP (only minor implication is that StateDescriptor now virtual)
• Cleanup solvers (from Riot branch) particularly BiCGStab. Still needs further testing. Volunteers wanted

BR

• working on downstream code
• looking at compiler warning

FG

• running INCITE sims
• added WIP Athena++-style sph/cyl coordinates
• changes seem to be self-contained (i.e., no downstream implications), and compile time option
• has Keplerian disk example in AthenaPK
• disk-advection example to be done
• Can we use topological elements for functions?

PG

• focused on INCITE runs
• AthenaPK cleanups

Non-WIP PRs

• Refactor Region Size #918 -- PG & BR/PM will review
• Update Iterative Tasking Infrastructure #917 -- has two reviews, will merge
• Geometric Multigrid #911
• PEP 1 #907 -- BP will check if there's a straightforward example to review, PG & JM
• AMR for non-cell centered fields #904 PG will review
