Attendees:

ECP Updates

[MS-19/04] Ghost Cells
- Ghost cell filter for structured cells has been merged in.
- Matt Larsen has checked in some similar code for extracting regions from structured cells.
- Going to absorb that back into Dave's work
- After that we can declare success.
- Still need to add user's guide documentation.
- Matt brought up that the ghost cell field is stored in UInt8, which is not recognized by filters by default.
[MS-19/05] Merge Points
- Ken has an implementation in a merge request.
- Working through CUDA compile error.
[MS-19/06] Connected Components
- Ollie working on bug fixes.
- Adding a filter in addition to a worklet.
- Almost at the point to submit an MR
[MS-19/07] Advect Time Varying
- Some new grid evaluator MRs are in, but there are some issues with CUDA. Still struggling with this. Cannot replicate on local machine.

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

[MS-19/09] Path Geometry
- Not started
[MS-20/01] Lightweight Cell Library
- Sujin is wrapping up tests for hex and quad and will then be able to show what is available.
[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
- Working on fixing normals to be consistent across surface.
[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
