ECP Updates

  • Need new KPP-3 metrics
    • Only "Integration" metric is due by April 1
    • Will be similar to one of the KPP-3 metrics we already have (app support)
    • Information available on confluence
    • Interesting change: metrics are accumulative
      • Example: if AD project X is using VTK-m in FY20 and FY21, we get to count that twice
      • In light of that, should we move away from the cross product of app x algorithm and instead just count apps using VTK-m?
  • Don't forget to put in your quarterly report

ECP deliverable updates

FY19Q2

  • [MS-19/04] Ghost Cells
    • Code is all in.
    • Working on user guide. Some changes to the MR and then we will be done.
  • [MS-19/05] Merge Points
    • Implementation has been merged in.
    • User guide is update.
  • [MS-19/06] Connected Components
    • Robert has reviewed an MR and given some feedback.
    • There are a few things to work on.
  • [MS-19/07] Advect Time Varying
    • There is an MR in to complete the work. Dave is reviewing.
    • Update user guide. Dave volunteers to do this part.

FY19Q3

  • [MS-19/08] Point Movement 2
    • There are already some filters in for point movement.
    • Still need some user's guide documentation

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.
  • [MS-20/03] Feature-Sensitive Surface Norm
    • Still working on bitfield implementation
      • Needed for graph traversal
    • Everything else is complete
  • [MS-20/04] VTK-m Release 3
    • On track
  • [MS-20/05] Cell Metrics
    • Daniel and Brent has been working on this a while.
    • Steven Walten will take over soon although Brent will be around a bit longer than originally anticipated.
  • [MS-20/06] Contouring
    • Need to support all cell types
  • [MS-20/07] Advanced Flow Algorithms
    • Still deciding what we want to do.
    • Dave is working on generalizing cell lookups and evaluators to work on all grid types

Rountable notes

Matt has added image-based testing to Ascent. Discovered that line drawing is nondeterministic (but it is because atomics are being used).

Hey, don't forget about DOECGF. Hotel registration due by the end of the week.
