Tentative agenda

Updates

JM

  • Still chasing down asymmetries
    • found bug in refinement checks
    • some issue still persist in Riot
  • Fixed mem alignment for hdf5 io
  • added doc for A/SMR

LR

  • wrote extended MHD code separately (will move some new interfaces upstream eventually)
  • generalized stokes update work (in fine advection example)

AR

  • some comparison between Parthenon and raw OpenACC/MP performance were quite favorable for Parthenon
  • current Flash layout
    • some rewrite in C++
    • some interface to legacy Fortran code

PG

  • added support for unint64 in particles
    • breaking behavior is that particles now carry an id by default (can be disabled via metadata)
  • CI containers finally work with newer software stack (biggest issue of building/linking Ascent stack got solved)
  • In process of cleaning up OpenPMD PR. Should be ready for final review next week.

Parthenon dev meeting

  • updated workshop schedule in wiki
  • someone in Ann Arbor will send final info next week (when/where to start)
  • everyone is invited to update the wiki with ideas etc

Review non-WIP PRs

  • 1253 Brandon might review
  • 1242 Someone from Riot should test
  • 1239 PG will review
  • 1162 LR and JM view review
  • Forthcoming: openPMD JM/BW for review
    • discussion: enable by default -- potentially yes, openpmd already compiles internally, PG will check how complicated it is to integrate ADIOS2 as well
