Telecon: 2023 12 13

2023/12/13 Meeting

Updates

• SC23 Tutorial -- went well -- a handful of engaged folks.
• Nicole: Working on WarpX Particle Advection support + ideas for plotting streamlines
• Nicole: Working on refactoring / unifying Ascent's logging
• Cyrus completed CI Spack updates for Conduit and Ascent
• Cyrus: Working on moving to new raja-based data binning (old code was openmp CPU only)
• Ascent develop + CI checks have moved to VTK-m 2.1
  • Q: We are not using rocthrust in our CI builds, or build_ascent -- are there performance impacts?
    • A: We do need thrust or else hip won't work.
  • We are working on merging several PRs that require VTK-m 2.1
• VTK-m 2.2 RC will be made before end of 2023
• We plan to release Ascent 0.9.3 in January
• Ascent should move to builds with VTK-m + MPI (shadow volume, particle advection, etc)
  • DIY has all-to-all issue that needs to be fixed (related to Contour Tree issues that Gunther reported)

Discussion

• Ping Abhishek about particle stuff he did and getting it into ascent

• 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)

• UO still working on ARMWind use cases for KPP3+1

• Meghanto's has Python extract to create GLFTs (only works for iso surfaces)

• Possible future: Manish to get shadow volume rendering into ascent
