Einstein Toolkit Meeting: 1/16/2020 Present: Steve, Roland, Liu Haoyang, Christopher Evans, Yosef, Alois Peter Schaffarczyk, Zach, Helvi, Babiuc, Eric West, Zhao Zhi-Chao
Requiring C++11: All machines have new enough compiler support now. No objections. Working Group Update: Slides: https://docs.google.com/presentation/d/1oGfijsztDHCn7eFxD8ihCZ-U02QrBjGNox_RBCbOGdc/edit?usp=sharing Uses hybrid EOS, piecewise polytrop, cold initial data, then switch to gamma law once heat is generated Excellent agreement with Whiskey Could this replace the existing TOV solver? Zach will talk to Leo about this. New codes for the next release: Baikal ETK code from Zach - issue of runtime vs. compile time options, about 6 to 8 BSSN kernels and options (e.g. finite difference order) at runtime. Ticket for review exists, but Zach needs to update the code. Helvi volunteers to review this thorn. SphericalBSSN, SphericalMHD - No updates, 2 papers need to come out, and so the thorns probably won't be available until October. Upgrades to IllinoisGRMHD - add single & piecewies polytrope test runs, adds a lot of documentation, plus support hybrid EOS, Roland volunteers to review TOV code - Link to that in the presentation, works with piecewise polytrope (NRPY) Leo has a version that works in C that's faster. Do we include it? Discuss again in 1 to 2 weeks time. Presync - Nothing much. Try to give another update next week. Self-Force - Peter will update us next week. APS meeting: Roland and Helvi will attend. Yosef and Zach will go, and Peter probably will. Arrange meetup? Getting rid of CactusCode.org: http://einsteintoolkit.org/cactuscode.html Tell me what else we need here? Add original authors? Next ET meeting in US is in the first week in August Will take volunteers for the organizing committee: Helvi will help. Don't be shy about asking for travel support for students Next ET meeting in EU... Bruno will look into this. Need volunteers for chairs for the next few weeks... Roland next week Helvi will take notes Put this item on beginning of the agenda in the future? Presync is the next working group update Alois is planning to attend the meeting and using the toolkit more. Any impact of new NS measurements on the favored EOSs? Zach probably knows more about it. _______________________________________________ Users mailing list [email protected] http://lists.einsteintoolkit.org/mailman/listinfo/users
