ECP task updates

ECP/VTK-m Project Management

Roundtable

Expect to release 1.7.1 this week.

When updating the tests, Ken noticed some discrepancies in the rendering for some types of components. Who is now responsible for rendering and can take a look at this:

• MapperQuad colors are wrong
• MapperConnectivity is buggy
• MapperCylinder just does not work

They are probably not used. Maybe they should be deprecated.

LSSw whitepaper: a big part of Jim's response is a question of whether everything should be in VTK-m or if there is still stuff that should be otherwise. We should give some thought on what should or shouldn't be in VTK-m and have a reasonable argument for it.

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.
