Chair: Samuel C Minutes: Bill G * SPEC benchmark contribution [https://bitbucket.org/einsteintoolkit/tickets/issues/2470 task] [RH, SB] Steve, Assume no one has done anything yet, but to keep on the agenda. Should start in December. * upcoming release planning (1.5 weeks to go, -1 weeks to feature freeze, -1 weeks to have everything reviewed) [RH] Roland, weeks to go, freeze was last week, no more changes. Name is as below. Nov 30th is the release, Monday after Thanksgiving. Gallery examples, two are finished and uploaded, BNS and scalar wave example. Work by Miguel and Steve. Miguel, has uploaded everything. Steve, trying to get the Mathematica setup right. Needs to have a couple of different packages installed and X windows. Have not had luck with LSU running X11 back to his machine. Will try to get around any firewalls, or go into the office. Tried downloading to laptop on Windows partition will not run SimulationTools executable from Windows. Steve wants a Python script to make the plots. Done in the next week. Bill, has run Poisson and looks fine. Made the Visit plot. ** release name: DeWitt-Morette https://en.wikipedia.org/wiki/C%C3%A9cile_DeWitt-Morette Besides physics and mathematics, she is famous for starting the Les Houches School of Physics, https://www.houches-school-physics.com/en/ . ** release date: November 30th ** Gallery test runners search [[Release Details]] [RH] *** [https://bitbucket.org/einsteintoolkit/tickets/issues/2175/test-single-stable-neutron-star-example#reopen Single, stable neutron star] [Miguel Gracia] (done) *** [https://bitbucket.org/einsteintoolkit/tickets/issues/2174/test-multi-patch-scalar-wave-equation Multi Patch Scalar Wave Equation] [Rahime Matur] (done) *** [https://bitbucket.org/einsteintoolkit/tickets/issues/2173/test-poisson-equation-example Poisson equation] [Bill Gabella] (in progress) *** [https://bitbucket.org/einsteintoolkit/tickets/issues/2176/test-binary-neutron-star-example Binary neutron star] [Beyhan Karakaş] (done) *** [https://bitbucket.org/einsteintoolkit/tickets/issues/2172/test-binary-black-hole-gw150914-example Binary black hole GW150914] [Steve Brandt] (in progress) ** release testsuite [http://einsteintoolkit.org/testsuite_results/index.php status] Roland, Not a lot of news. Did re-run on supported clusters, fixed the two punctures failure, it required running with higher resolution. Fixed a bug in Carpet's flipped in one direction. Affected the PETSc test on Queen Bee. Golub cluster has the largest number of failures, is using Intel and Slurm. Stampede does better than Golub. Maybe Intel compiler is defaulting to more agressive compilation. Roland, drafted a release announcement and Maintainers should have a copy. Please read and make comments. Two persons are new: Jonah Miller (doc Kranc) and Matthew Ely (Llama support). If there are others please tell Roland so he can get permissions and their names in the Zenodo and citation. ** [https://bitbucket.org/einsteintoolkit/tickets/issues?milestone=ET_2020_11&status=open&status=new Tickets marked for the upcoming release] ** [https://bitbucket.org/einsteintoolkit/tickets/issues?kind=bug&priority=major&priority=blocker&priority=critical&status=new&status=open Open bugs of severity major or worse] Roland, Tkt #2479 has existed for some time and .. You can depend on parameters of Thorns that are not active, which it should not. Saw in some of the testsuite tests. Thorn needed to compile even if not used in calculation. Not a crucial bug. * [https://www.einsteintoolkit.org/tools/unanswered.php unanswered question on mailing list] / [https://bitbucket.org/einsteintoolkit/tickets/issues?status=open&status=new&sort=-updated_on open tickets sorted by update time] / [https://bitbucket.org/einsteintoolkit/tickets/issues?status=new&status=open&sort=-updated_on&q=Please%20review tickets ready for review] * any other business Steve, we are not meeting next week, Thanksgiving in the US. Next meeting Thursday December 3rd---Roland is chair and Miguel is minute taker. Zach, LaTeX parser update with Ken. Working on parsing the BSSN equations as exist in Baumgarte's Spherical NR and Baikal. Mostly functionally where we need to be. Working on the documentation. Also a nice Unit Testing infrastructure---cannot rely on Sympy simplification being very deterministic, so created a novel method involving hashing symbols into high precision numbers. Using Sympy's multiprecision math. Used to evaluate that expressions are equivalent. Roland, Probing with floating point numbers, what about exact math, fractions, etc. Zach, good idea. -- ============================== William Gabella Research Assistant Professor Department of Physics and Astronomy Nashville, TN USA (o) 615-343-2713 _______________________________________________ Users mailing list [email protected] http://lists.einsteintoolkit.org/mailman/listinfo/users
