- Subset I/O capability
- Periodic meshes
- https://github.com/MPAS-Dev/MPAS/issues/1307 "reference time" for output_interval in streams

Participants: Adrian, Dom, Matt, Mark, Michael
-
1352 Merge it
-
1350 LANL are interested — it’s just that ACME requires extensive testing of any new changes, particularly threading changes
Nothing to discuss here this week
- Phil Jones is lead of ACME perf team, some people on that team (Matt Norman) may be interested in more discussion
- maybe best way to start would be to follow-up on Phil’s e-mail from last week
- Mark will respond, Michael will follow-up with specific topics for discussion
- Related topic: would be useful for ocean and sea-ice to have separate halo widths for 2-d vs 3-d variables
- performance tests on KNL - timing is completely dominated by communication for barotropic solve
- Example of exchanging just the inner layer halo cells
