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.

Potential progress Colleen Bertoni from ANL to put in Ascent configuration editor.
