ECP deliverable updates

FY19Q3

• [MS-19/08] Point Movement 2
  • Done!

FY19Q4

• [MS-19/09] Path Geometry
  • Added polyline support to VTK-m explicit cell sets
• [MS-20/01] Lightweight Cell Library
  • Have implementation for Quad and implementing some tests using random cell generation.
  • Other cells will be implemented similarly.
• [MS-20/02] Specialized Data Models
  • Mark Kim working on this.
• [MS-20/03] Feature-Sensitive Surface Norm
  • Allie getting back on that after being out of the office for a while
• [MS-20/04] VTK-m Release 3
  • On track
  • Probably June would be a good time for a release.
• [MS-20/05] Cell Metrics
  • Brent and Daniel are working on an MR.
  • Steven Walton is getting engaged on this.
  • Initial MR will only be about 1/3 of the metrics.
    • First MR is moving forward
  • Will advance after that.
  • Hank might have to jump in during the summer.
• [MS-20/06] Contouring
  • Will model the problem after triangulation. Have different contouring for each cell type.
  • Ollie looking into VTK implementation and flying edge paper.
• [MS-20/07] Advanced Flow Algorithms
  • Abhishek and Dave have been working on performance fixes for unstructured grids.
  • James and Dave have been fixing bugs for distributed memory and for unstructured grids.

Hackathon

The hackathon will be held in Albuquerque starting July 30. Everyone planning on attending should register. Go to Hackathon 2019-07-30 for details.

Rountable notes

We should try to collect some ECP data so that as we do reporting we can quickly generate relevant images. It would be great if we could also share across ALPINE and other vis projects.

• Terry Turton has collected some stuff from LANL. Not sure if can be sent out.
  • She might have a list of distributed data in different places

Ken ran into some issues on CUDA that he thinks is related to an assumption in VTK-m that the structure of virtual objects will be the same on the host and device (even if the virtual table is different). That might not be the case with the Microsoft compiler.

No meetings next two weeks.
