ECP/VTK-m Project Management

Roundtable

Has anyone been looking at compiling both VTK-m and Ascent over Kokkos? We have had to do some special things under CUDA, and we might expect there to be some integration issues under Kokkos and its various backends as well.

Matt working on WarpX highlight.

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.
