Teleconference 2024-07-03

Attendees: Ken Moreland (ORNL), Dave Pugmire (ORNL), Jeff Amstutz (Nvidia), Silvio Rizzi (ANL)

There was not a quorum in attendance (being the day before the holiday). There was a brief discussion of the ANARI VTK-m interface before signing off.

OASIS Deliverables

• Address requests for support, improvement, and new features by current and potential applications such as XGC and WarpX as well as other users of ParaView, VisIt, and Ascent.
• Strengthen operation of VTK-m on Aurora.
• Improve documentation with automatic generation and web deployment.
• Ensure proper building and running at OLCF, ALCF, and NERSC through Spack.

VTK-m Releases

Release candidates for VTK-m 2.1.1 and 2.2.0 are out.

Viskores / HPSF

Have formalized the initial TSC. Ken is considering adding the following voting members to the TSC to represent their respective institutions and projects.

• Silvio Rizzi, representing needs of ANL/ALCF
• Nicole Marsaglia, representing Ascent and LLNL
• Gunther Weber, representing topology, LBL, NERSC?

We need a plan for moving from VTK-m to Viskores. People are already starting to ask about the new name, so we should pull together something soon and have a plan forward. Also, there is an opportunity to request funding from the LF now if we get in. What would be an estimate of what we would need?

Roundtable

Dave working with Jeff on ANARI rendering. Jeff has sent Dave some boilerplate ANARI backend, and Dave is looking into hook into the backend.
