ECP Updates

ECP deliverable updates

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.

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

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?

Hackathon?

Matt is going through some pain compiling Ascent (and VTK-m along with it) on an "interesting" computer at LLNL (Butte). Working on automated testing on that platform.

RuntimeDeviceTracker updated so it is always per-thread.

MR to introduce a test that installs VTK-m and then compiles something against it to make sure that the install is correct.

Sujin updating CellLocator to be more uniform and to follow VTK-m coding conventions better. Also making a generic cell locator that does the right thing for whatever cell set it is created for.

Berk is working on a library and Schema for ADIOS to create a VTK-m data from these. Should give us something similar to XDMF.
