ECP Updates

• KPP-3 Verification
  • Need to update verification details in VTK-m KPP-3 Strategies
  • In particular, Nyx and WDMApp need to be fleshed out
• Finalize next P6 Activity
• Get key people on AD allocations
  • The following AD codes will be running early on Frontier
    • LatticeQCD, ExaSMR, ExaSky (HACC), CANDLE, EQSIM, Subsurface, WDMApp, WarpX
    • For WarpX: they have already run their KPP-1. Further KPP-3 will likely be in ALPINE's project (CSC340).
  • If we are providing software assistance for any of these, or we are planning a KPP-3, we should have a member as part of their allocation.
• Let's think about possible highlights
  • App engagement
  • Success with porting (e.g. run on Aurora)
  • Engagement with other ST teams (e.g. using Kokkos)
  • WDM
  • Possible highlight slide on particle advection with WarpX
  • Some work with MFIX. Going to execute on Summit. Might wait for run on early access machine before highlight.

Porting Activities

ECP task updates

ECP/VTK-m Project Management

Roundtable

No meeting next week.

Nicole Marsaglia could use help migrating code from VTK-h to VTK-m. Can Kitware do some of this work as part of the support Ascent task for ECP/VTK-m?

Should we change the implementation of CoordinateSystems to actually be stored as Fields?

Status of dashboards

• The "external" buildbot builds no longer run.
  • dragnipur already moved to new system.
  • What is the status of osheim? It is not run on buildbot but not in the runners either.

R&D100?

• Thinking of submitting for 2022
• Big stumbling block: needs to be "created" between Jan 2021 to March 2022
• Plan: Release VTK-m 2.0, do a copyright assertion

Rename master branch?

• Need to wait for some changes to git before the transition (for some automated features of repo).
• Can we for a time have a master that mirrors the new default?
  • Don't know, but seems possible. Will have to look into that.
