ECP task updates

ECP/VTK-m Project Management

Roundtable

Gunther brings up an issue where he tried contour trees with large data sets that ran slowly on CUDA but crashed with HIP/Kokkos. This might be an issue of lack of proper unified memory on the HIP/Kokkos end. We are not sure.

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.
