MPAS-Developer Telecon:

Date: 13 March 2017
Time: 11:00 MDT / 19:00 CET

Call-in number: 1-866-740-1260
Access Code: 4978161

Agenda Topics:

  1. Framework modifications:
  2. Scoping and brainstorming: How can we envision a subset I/O capability looking from a user perspective?
    • MPAS-Atmosphere will soon need an efficient way to read grid cells/edges/vertices only along the perimeter of a large region
    • Would this capability be useful to output, e.g., a single ocean basin?
    • Handling I/O on a subset of mesh elements may not be too difficult in the mpas_io module
    • How might users and developers describe the subset of elements
  3. Standing topics:
  4. Anyone have experience with pure column configurations?

Notes:

Participants: Adrian, Matt, Mark

  • Logging module: next step would be to convert all cores in 'develop'

    • start with framework (any complications should turn up there)
    • maybe at some point we need to revisit developer guidelines (e.g., should every commit compile)
    • for the conversion, don't leave in old write statements -- we can always compare before and after branches
    • changes to sea-ice column package that would be needed for logging module have just been merged
    • Mark: what about timeline for individual cores? may take until after spring break
    • if timeline is too long, other merges into develop may cause conflicts
    • maybe it would be good if we all worked on this the same week: next week 20-24 March - next telecon we'll get instructions
    • maybe come up with a script or vim macro

  • Framework PRs:

    • 1255 Adrian will update the initial comment, Michael will merge
    • 1237 a test with ACME isn't coming out right - more investigation needed
    • 1227 not immediately needed, see whether there is a more general solution?

  • Subset I/O capability:

    • An initial document will be put together for the next telecon

  • Standing topics:

    • Merge of CIME 5.2 is still in progress

  • Single-column configurations: does anyone have experience with this?

    • MPAS-Ocean has been run with 4x4, doubly periodic configuration
    • MPAS-Atmosphere has been run with 2xn doubly periodic configuration
    • Current mesh-generation software probably won't work with a single column
    • Adrian may experiment with code to create a single-column mesh
      • Can we have cellsOnCell field for a cell refer to the cell itself?
