ECP/VTK-m Project Management

Roundtable

Bronson Messner approached Ken asking if VTK-m could do a KPP-3 run on Frontier (that did not need to stress the file system). After some discussion, it made sense to run the In Situ benchmark on a lot of processes. The benchmark needs to be fixed for MPI run. The two items to fix are a correct parallel rendering (image composite/reduction) and a correct partitioning of the input. Once that is done, it should be trivial to run the small program at scale.

Decided on doing 4 "early" KPP-3 metrics

• Flow for WarpX and/or WDMApp
  • Springboard off Abhishek's thesis work
• Ascent integration
• ParaView integration
• VisIt integration

R&D100?

• Thinking of submitting for 2023
• Big stumbling block: needs to be "created" between Jan 2022 to March 2023
• Plan: Release VTK-m 2.0, do a copyright assertion
