Participants: Matt, Adrian, Dom, Mark

Framework PRs

• 1246:

  • Who is finished? LI done, SI done, OCN done, ATM not done (by Wednesday end of day?)
  • can make commits directly to branch
    • or make a branch, then fast-forward merge
  • cherry-pick Mark’s ocean changes onto log_module branch
  • enable rerere to avoid resolving the same conflicts more than once
  • separate PR to remove old stream redirection, also to remove mpas_abort

• 1237:

  • Phil Jones helping to debug

• 1227:

  • Michael needs to get on this

• 1086:

  • Decided to just merge the “final_only”, create a separate PR for stream interval attributes (Dom to create a dummy PR for this)

Periodic meshes

• is this handled right now with direct addressing? yes, and the geometry calculations are what are problematic right now
• e.g., any computation that depends on xCell, etc., will be complicated
• Philip Wolfram had done some work on operators that would inherently support periodicity
• David Lee could also benefit from some generalized code to compute distances across boundaries
• How should we handle this?
• If we had really general mesh generator, it could know about periodicity while iterating
• Add this as a standing topic
