ECP task updates

ECP/VTK-m Project Management

Roundtable

WarpX has been pushing for a visualization for keynote as ISAV. Using Ascent/VTK-m under the covers. Been working through issues on that.

David Pugmire gave short 10 min presentation to Alpine internal review. It would be good to have him repeat it for VTK-m. - Maybe have Silvio present, too.

Follow up for benchmarking of Kokkos. Do we have profiling of what is being run during the "slow" filter benchmarks? Sujin is working on changes to the Kokkos device adapter that use Kokkos algorithms like scan and sort for the cases where it is supported. After that we can benchmark again.

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.
