Andrew Gaspar finished up that warnings PR by checking error codes. Engaged in discussions on a potential LANL proxy app. Will be engaging in discussion on dense on block later today.
Josh has been doing some fix ups on CI, RZAnsel machine configuration, and some basic work on performance CI.
Carola is still looking at weak scaling of advection problem.
Josh has been doing some testing trying to make the code more agnostic to whether they're parallelizing over mesh block packs vs. individual mesh blocks. Wants to discuss more in a bit.
Jonah has been working on restoring Athena++ boundary conditions features. https://github.com/lanl/parthenon/pull/332
More working particles, including buffer packing and testing. Open question about how to parallelize on
Phil was working on boundary exchanges, but ran into performance degradations. Needs performance continuous testing to catch earlier!!!
Forrest at conference this week.
Josh Brown and Phil are looking at this.
Some discussion on magic strings. Generally we agreed that structs with a bunch of function pointers are better.
