ECP Updates

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

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?

Rob has been working on getting rid of warnings from CUDA code. Some warnings have popped up because we are no longer suppressing lots of CUDA warnings about device calling host. These are legitimate issues.

Matt has been working with early CI testing on machines.

There is a customer building VTK-m with different compilers (with Sierra) with XLC and PGI. XLC and PGI take a long time to compile (with CUDA).
