ECP Updates

• KPP-3 integration metric due April 8
  • Hank is working on this
  • Might also need some guesses about other KPP-3 metrics for Final Design Report
• Starting to plan work detail for FY20 and beyond
  • All PI's: edit https://confluence.exascaleproject.org/display/STDA05/FY20-FY23+Activities+WorkSheet
  • Will send out pestering emails to PI's soon

ECP deliverable updates

FY19Q2

• [MS-19/04] Ghost Cells
  • Done.
• [MS-19/05] Merge Points
  • Done.
• [MS-19/06] Connected Components
  • Merge requests are in
    • Which is the most recent one?
    • Might be listed in closed instead of merged
  • Sent highlight slide
  • Missing short user's manual
• [MS-19/07] Advect Time Varying
  • MR is in
  • Should be an MR for the user's guide

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
  • Progress seems a bit slow.
  • Will make a sprint during the Spring semester
• [MS-20/06] Contouring
  • Need to support all cell types
• [MS-20/07] Advanced Flow Algorithms
  • 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

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.

There have been some code checked in that does not follow VTK-m coding styles (such as member variables not being capitalized, always using this pointer). We should be more vigilant during code reviews.

There are some new warnings on the dashboard. Are those in the process of getting fixed?
