Attendees:

ECP Updates

• Need to bias the KPP-3 Integration metric with a positive current value (what we have done so far)
  • Hank working on this
• Basis of Estimate due today!
• Starting to plan work detail for FY20 and beyond
  • All PI's: edit https://confluence.exascaleproject.org/display/STDA05/FY20-FY23+Activities+WorkSheet
  • Please finish filling this out soon.

ECP deliverable updates

FY19Q3

• [MS-19/08] Point Movement 2
  • Done except user's guide.

FY19Q4

• [MS-19/09] Path Geometry
  • Ramping up
  • Some of the functionality is already there
  • Probably need to add a poly-line cell type
• [MS-20/01] Lightweight Cell Library
  • Been doing some changes on the interface to the VTK-m cell library.
  • Most of the underlying library is ready.
  • Almost ready.
  • Still need to implement VTK-m data around it.
• [MS-20/02] Specialized Data Models
  • Dave P and Sujin talked about how to roll in some generalized extruded meshes.
• [MS-20/03] Feature-Sensitive Surface Norm
  • Bumped up CUDA version so that we have our required CUDA 9
  • Can get back to actual algorithm
• [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.
  • Initial MR will only be about 1/3 of the metrics.
  • Will advance after that.
• [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
  • Merged in fix to do double precision correctly.
  • Still deciding what we want to do.
    • Planning on talking during DOECGF
    • Hybrid parallel seems like a good way to go
  • Organizing work with ALPINE and others

Rountable notes

Upcoming events:

• IXPUG In Situ Analysis Hackathon
  • May 28-30
  • https://www.ixpug.org/events/in-situ-hackathon
  • Reservations due today
• CEED Annual Meeting
  • August 6-8

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

Hackathon?

Slides from DOECGF panel. (Highlights of VTK-m at scale we can send to Jim.)
