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
Working Group Update: Slides:
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
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
a lot of documentation, plus support hybrid EOS,
Roland volunteers to review
TOV code - Link to that in the presentation, works with piecewise
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.
Getting rid of CactusCode.org:
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.
