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 May 1
  • Basically need to provide budgets for FY20-23.
    • Need to work with your financial people.
    • Last chance to decide on subcontracts.
    • Budget pages: https://confluence.exascaleproject.org/download/attachments/61904390/BOE%20CD-2.xlsx?version=1&modificationDate=1554499415120&api=v2
  • Kitware and Oregon only need to provide total cost per year right now.
  • Ken sent out budget breakdown and suggested per-year spending.
    • Got clarification. We can redistribute the "FY20" funds to the later years.
    • Send Ken any modifications to this this week.
  • Review confluence page: https://docs.google.com/document/d/1L44kTtwKi0SgeSJxt62OGGI7hpfpte-OHm0V0B6vsg8/edit#heading=h.hk0so9awvgd1

ECP deliverable updates

FY19Q3

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

FY19Q4

• [MS-19/09] Path Geometry
  • Not started
  • Some of the functionality is already there
• [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
  • Some work on how XGC used a rotated triangular grid for a bunch of wedges.
  • Need to generalize some code written by Matt.
  • Pulling in code from other contributors.
    • Connect up with Berk who is picking up XGC work from before.
  • Need to brainstorm on what other features would be useful.
• [MS-20/03] Feature-Sensitive Surface Norm
  • First pass in a MR
    • Need to wait until CUDA 8 off all dashboards
    • Should be walking the graph traversal
• [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 is getting back on this.
• [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
  • Dave is working on generalizing cell lookups and evaluators to work on all grid types
  • Dave has been working on distributed memory advection

Rountable notes

Grouping copyright to license file. Can we pull the trigger?

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?

No meeting next week.
