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.
- Ascent team solved ray tracing bug in VTK-m 2.2
- Strengthen operation of VTK-m on Aurora.
- There are still some failing tests.
- They may be a problem with cell location, which might be an issue with Variant.
- Having Intel look into the previously identified union/variant bug found.
- Improve documentation with automatic generation and web deployment.
- User's guide continues to improve.
- Ensure proper building and running at OLCF, ALCF, and NERSC through Spack.
- Ken verified that Slack builds work on Perlmutter and Frontier.
- Silvio will establish contact for Ken of someone at ALCF tasked with compiling stuff with Spack. Request that they also compile VTK-m/Kokkos.
VTK-m Releases
Release 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 have a plan to transition from VTK-m to Viskores. We are hoping for some funding from the HPSF to do this.
Roundtable
Cyrus had a question about how VTK-m manages device streams and how that interfaces with Kokkos. Ken thinks VTK-m establishes a device stream per CPU core so that multiple CPU threads could schedule things simultaneously. Cyrus might need a way to set the device stream to use.
