Rountable notes

Grouping copyright to license file. Can we pull the trigger?

  • Lets do it

No more default device adapter!

We should try to collect some ECP data so that as we do reporting we can quickly generate relevant images. It would be great if we could also share across ALPINE and other vis projects.

  • Terry Turton has collected some stuff from LANL. Not sure if can be sent out.
    • She might have a list of distributed data in different places

Hackathon?

Jim has been asking for examples of running VTK-m at scale. We have done this, although we are not really using ghost cells.

DOECGF talk: what I did with VTK-m at scale:

  • Dave Pugmire
  • Matt Larsen
  • Rob Maynard
  • Hank will be the organizers

No meeting next week.
