Einstein Toolkit Meeting Minutes
by Frank Loeffler 15 Sep '14

15 Sep '14

Hi, We had 12 people present: Phillip, Josh, Peter, Steven, Frank, Jonah, Erik, Barry, Zach, Matt, Ian, and Roland. Besides mentioning a few "minor" tickets, the top discussions were: - how to expand variables in parameter files (a question which now seems to be settled, more here: https://trac.einsteintoolkit.org/ticket/1651) - git move: should wait until Jenkins comes up again, at least if this isn't too far into the future (hopefully this week) - GRHydro/Illinois/Whisky inconsistency: reason still unknown. Zach has more puzzle pieces, but they also pose more questions. It seems that we don't have an edge or even corner yet, and attention and interest is waining. What we know so far (please correct me if I am wrong): - The 2-norm of the Ham. constraint is about 2x high with GRHydro than both with Whisky and the Illinois code, plus there are differences in the drift of the central density (probably related). - This does happen with HLLE, but not Marquina - It does not happen in Cowling - Nobody could find a major difference in the HLLE code - The Illinois code uses another definition for the velocity - a possible source for this difference, but Whisky uses the same as GRHydro Frank

Hi Present at todays meeting were: Roland, Jonah, Erik, Matt, Steve, Peter, Frank. We've talked about a couple of active tickets, in particular: - 1396: GetComponents: Display prompts of executed commands (discussion) Steve will look into bash-magic (or something else) to solve this. - 1517: Make Simfactory tell you what it's doing (discussion) Steve accepted the ticket. - 1388: New thorn MemSpeed (reviewed ok) Erik will add the thorn to the ET thornlist. - 1651: Problems with expansions in parameter files (new patch) Roland will look at the new patch. Nobody really tested the new git transition repositories, but at least Steve and Peter volunteered to do so soon. The URL for the thornlist to test is: https://svn.einsteintoolkit.org/manifest/trunk/git_testing.th Frank Loeffler

Fwd: Blue Waters Advanced User Workshop and yt development workshop
by Matthew Turk 05 Sep '14

05 Sep '14

Hi everyone, I just wanted to bring to your attention that there's going to be a yt (yt-project.org) development workshop at NCSA in mid-October, if anyone is interested in attending. For the last couple months, Roland, Sherwood and I have been working on and off on yt+Cactus work. The last remaining sticking point seems to be refinement boundaries that coincide with processor tiles; I'm prepping a detailed question-laden email that hopefully covers this last case, which I'll send to this list. But, this workshop would also give a good opportunity to meet in person and see what other items are remaining, and how best to shift yt to accommodate ET data. -Matt ---------- Forwarded message ---------- From: <help+bw(a)ncsa.illinois.edu> Date: Mon, Sep 1, 2014 at 3:16 PM Subject: Blue Waters Advanced User Workshop and yt development workshop To: Blue Waters Announcements <noreply(a)ncsa.illinois.edu> We are pleased to announce a three-day, hands-on oriented advanced user workshop about using Blue Waters to its fullest potential. Representatives from Cray, Allinea, PGI and NVIDIA will be on-site to present material and interact with attendees so bring your own code. This work shop is targeting existing or recently allocated, advanced users of Blue Waters. In conjunction with the Blue Waters Advanced User workshop, we are pleased to invite people who are interested in participating in development of the yt project (yt-project.org) to a two-day hands-on development workshop, focusing on parallel and in situ analysis, stabilizing existing data format front-ends, and expanding the capabilities of yt to take advantage of supercomputing resources. Blue Waters Advanced User workshop https://bluewaters.ncsa.illinois.edu/blue-waters-advanced-user-workshop-oct… yt development workshop https://bluewaters.ncsa.illinois.edu/yt-development-workshop-oct-16-17-2014 We hope to see you here.
