2024/3/6 Meeting

Updates

  • Nicole: Working on particle advection seed placement

  • Nicole: Working on a uniform grid resampling filter

  • Nicole needs to start working on Material Interface Reconstruction in Ascent for CEA/NNSA due Q2Y24.

    • Wording: "Implement material interface reconstruction in VTK-m for Ascent"
  • User from National Center for High Technology was having issues using expressions

    • Added a new filter to create a derived field that is a power of the original field
    • Still may be having issues not getting the derived field results from the expression
    • Noticed interesting query workflow: Queries always happen first if unattached to a pipeline, if attached to pipeline the results go nowhere.
    • Need to formalize Query vs. Expression use cases and workflow
      • Expression language used for expressions and queries
  • Cyrus completing CI spack changes when he can (waiting on Umpire-- released last week)

  • Cyrus worked on RAJA data binning

  • Andres + Argonne + Utah state for steering

  • NASA bug with striding; need to circle back

  • Unstructured meshes with heterogeneous data types

  • We plan to release Ascent 0.9.3 in March!

  • Hank invited to participate in PSAP proposal

    • Focus on ML + Ascent

Discussion

  • When to meet? How often?
    • Nicole: Send out a poll, start with once a month
  • Old:
    • Meghanto's PR for sampling we need to get in. (Sampling is also in VTK-m, so we would need to migrate some changes there as well)

      • In use for research/paper
    • Meghanto's has Python extract to create GLFTs (only works for iso surfaces)

      • Semi-frozen based on Meghanto's time constraints, may try to hand-off to Cyrus
    • Possible future: Manish to get shadow volume rendering into ascent

      • Frozen
