Telecon: 2022 02 23

2022/02/23 Meeting

Agenda

Discussion Topics:

• Ascent 0.8.0 release done

  • Updated public installs on Summit and Perlmutter
  • Using UMS on Summit (no more randomly purged builds)
  • Spack develop changes still in progress

• Crusher / Spock porting

  • Part of VTK-m have been built with HIP no rendering
  • What VTK-m HIP support expectations / time line (rendering)?

• Ghost Stuff - particle advection

  • Ghosts were gen-d by Ascent, passed to VTK-m, need to provide names to get them in use.

• Cell arrays with many variables in VTK-m (Energy Group)

Still Pending:

• VTK-m CUDA Arch vs Lib sizes?
  • we can explore making a path to directly pass sm_ZZ (we have a ticket for this in VTK-m)
• Cell Metrics (getting volume of each cell)
  • 2 VTK-m filters - Cell Metrics and Mesh Quality (similar, we should check Cell Metrics, we have looked at Mesh Quality)
  • We might want a fast path in VTK-m for cell metrics for structured grid
  • Cell Metrics is simpler than Mesh Quality
