ECP task updates

ECP/VTK-m Project Management

Roundtable

Discussion on mailing list about moving to C++17. We do not plan to move to C++17. However, there is some worry that if VTK-m libraries are compiled with C++17 (for Kokkos), will that cause issues with using them in applications compiled with C++14? A StackOverflow entry suggests this should be fine.

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.
