Individual/group updates

LANL/External CS

Jonas Lippuner

• Not sure about how to handle IsAllocation checks, there are multiple options, but beyond first true parse implementation PR
• Add a compile-time switch to turn of all sparse checks/machinery

LANL Physics

Jonah Miller

• Working on TOV start with self-gravity in Phoebeus (may or may not be ready for paper)
• Spoke with Kurt. He's used Athena++ for heliophysics, wants to use Parthenon, needs non-Cartesian coordinates, plans on implementing that and submitting PR

Ben Rayn

• Been working on downstream codes
• Trying to fix equilibrium solution of gas disk/torus around a spinning black hole

Josh Dolence

• Time set aside to write on paper

AthenaPK

Philipp Grete

• Finding interesting bugs via implementing super timestepping
• Currently fluxes are shared between all stages, should we keep this or add option to have separate fluxes for stages
• Also looking into the HDF5 PR. Proposing to make output format change in separate PR from HDF5 tuning
• Plan to implement capability to only include listed variables in boundary communication (regardless of metadata flags)

Forrest Glines

• No updates, working on proposals

Squashing commits

• Consensus is to squash by default, not sure how to set settings
