Project Randy

Previously:

Alan will get some time on Red Sky next week to try Utkarsh's patches. Nathan will also try running during this time.

Berk had a conversation with Randal Hand and is inspired by Alan running interactive up to 5K cores. Randal and Berk had a meeting and now have a plan forward to do the scalability tests themselves.

Pat has runs up to 8K cores. He has plans to run up to 16K (maybe 32K) very soon.

Today:

Alan ran on Red Sky: 4K cores, 1.1 trillion cells. Alan applied Utkarsh's patches to completely remove the progress update, and that noticeable improved the performance. We should have an option to turn off progress reports when the number of processes exceeds some number, say 100.

Alan is still having problems scaling up past 5.5K cores or so, but this might be caused by the Red Sky system itself. Nathan reports similar problems using solvers without ParaView at all.

Warning when ProcessRequest modifies itself

Previously:

A while ago we talked about adding a check to the executive that issues a warning if it detects that its MTime changes during a call to ProcessRequest. Whatever happened to that? I just spent 2 days tracking down a parallel pipeline update problem that would have been quickly alerted had this been in place (and was easily fixed once I put my own check in place).

Berk suggested first adding the check only to ParaView. We will see how that works, and then possibly move to VTK. Kitware will take care of that.

Book omissions and errata

Previously:

Lisa is going to create a bug-tracker like functionality for the Kitware books.

Transition to git

Branchy workflow. Tie in to stronger dashboard.

Install hooks in CMake? Marcus will be responsible for it.

Updates to the VTK submodule.
