Teleconference 2019-03-20

Attendees:

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. Just need to update documentation.
  • UInt8 has been added to the list of default types.
• [MS-19/05] Merge Points
  • Implementation has been merged in.
  • Still need to update documentation.
• [MS-19/06] Connected Components
  • Should have MR this week.
• [MS-19/07] Advect Time Varying
  • Abhishek and Rob have been helping with issues with the grid evaluating code.
  • Fallback is to consider time varying code we already have merged in.
    • Everything will work for uniform and structured.
    • Abhishek will go ahead and write a unit test for the backup.
  • Proposal: work on grid evaluator stack issue one more week. If it does not work by next meeting, let's fall back.

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
  • 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
  • Brent is working on this.
  • Steven Walten will take over soon as Brent is about to graduate.
• [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
