Porting Activities

ECP task updates

ECP/VTK-m Project Management


Matt has brought up some issues with compiling Ascent (more specifically, VTK-h) with newer versions of CMake. It is not totally clear what versions of CMake the issue comes up, but it has been noted that the dashboards do not use the latest versions. In particular, the highest version of CMake used for a CUDA build is 3.16. We need to check for newer versions of CMake.

Vicente will work on making a release. Matt has requested the release happen right before the removal of virtuals from implicit functions. We will start with a branch and a release candidate that Matt can add fixes to. Matt will be something of a guinea pig for this.

Wiki will go away at some point (and will definitely move soon). We should avoid using it for anything other than these notes.

We need some redesign design workflow for branchy release process

  • When we create a VTK-m release, we have a branch for that release (at least until the subsequent release).
  • New feature development continues on the main branch
  • _Bug fixes_ happen off the release branch
    • Get merged to both the release branch and the master branch
  • This in principal should already be supported by GitLab
    • Just create a merge request on a different branch
    • Will need to add support to gitlab-push
      • Ask VTK folks. They might just have a select few to do a special process.
    • Need to check that bot stuff works (CI builds, Do: merge, etc.)

Should think about releasing VTK-m 1.6, 2.0.

Filter redesign requirements:

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.
