ECP task updates

ECP/VTK-m Project Management

Review schedule changes.


Campaign to compile on new pre-exascale architectures by October.

  • Would organizing a virtual code sprint help (or hinder)?

Is sccache working with build:ubuntu1804_kokkos?

  • Fixed this morning.

Is there an issue with GCC 4.8 tests?

  • Does not seem to be an issue.
  • Well, actually, things like the deadlock in merge trees and broken connected components tests seem to be on GCC 4.8. Is it an issue with the compiler or the algorithms?

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.
