Chair: Roland, Minutes: Bill * Any other business or questions? None. [See below at the end of the meeting.] * SPEC benchmark contribution [https://bitbucket.org/einsteintoolkit/tickets/issues/2470 task] [RH, SB] Roland, Steve and Roland are working on. CCZ4 code will be submitted, okay with Spec who want different characteristics than last time. This is 8th order finite difference. Had to set it up with a plain make file---generate source file and Cactus bindings. Done soon-ish. Stripped down version of ETK repo cannot be generally shared, Steve and Roland have it. Someone added OpenACC versions of the kernels, so some work has been done. Steve, why we want a benchmark that does not compute zero---the OpenACC benchmark was very, very fast and result was zero. Should be a result that can be checked. OB, none * release planning [RH] https://docs.einsteintoolkit.org/et-docs/Release_Process https://docs.einsteintoolkit.org/et-docs/Release_Details Zach, Next release is late May, tentatively. Need test runners for the testsuites on supported machines. Roland ran them with scripting on Simfactory last time(s). Originally we farmed out the testsuites to people to test a couple of machines, on the clusters they are familiar with (from when Frank L was managing things). Clusters are becoming more difficult to login, two-factor etc, so maybe needs more individual attention. No action taken. Gallery examples volunteers: Steve, Binary Black Hole GW150914. Did not finish with Visit, other plots, some surface plot problem. Roland, bug in quasi-local measures (fixed 2-3 weeks ago) keeping the VTK files from being made. Use with Gabriele's new Kuibit package, instead of Visit: https://sbozzolo.github.io/kuibit/ Need to set OutVTK to not be zero. Miguel G, Poisson Equation Bill G, Multi-Patch Scalar Wave Equation Peter D, Single, stable (TOV) neutron star Atul K, Binary Neutron Star Zach, Possible new thorns from his group, MaxwellVacuum and MaxwellVacuumID (initial data). Also POWER Maria will review. Roland, has to clean up his version and move it to the Master branch and it will be ready for review. Steve, SimFactory Python 3 (upgrade). Roland's survey about needs/wants in SimFactory, ~20-30 responses. Will try to trim down the SimFactory functionality and that will play into compatibility with Python 3. Would like to build a SimFactory testsuite also. SimFactory in Jenkins ( https://www.jenkins.io/ ) is not tested---setup-silent build is tested, as is submit --testsuite option. Also the Python 3, "set language" problem, or locale problem, utf-8 and ascii, may or may not be a problem (big discussion between Roland and Steve). Updates to CondaPrim, SelfForce1D, and Canuda. Roland, really every change needs review, but for large changes we do the formal review. CondaPrim was from U of Arizona, and IllinoisGRMHD and we have not heard from them recently, so not likely to be ready. Canuda, Miguel Z, adds scalar field thorn, so more than an update, an actual new thorn. Helvi was responsible for it. Miguel, thorn is ready and I have been using it for years. We have internal cross-checked the thorn, believe it is stable, but has not gone through review process for ETK. Helvi is responsible for that. Roland, thought she might be late submitting request because January was very busy. Miguel Z will ask her about the status. Selfforce1D, Peter D, new implementation of equations for gravitational perturbation. So probably major, and will need a review. Might be ready by March 1st. Zach, deadline for officially proposing new items is March 1st. Want reviewers for the above. * ET-US 2021 workshop planning [RH] Need to get started on it, Roland wanted it at UIUC while hosting the Mid-West Relativity Meeting. With Covid, likely still virtual, so it could be anywhere for the host. Want people involved to organize the workshop. People from last committee, setup program, and school schedule. Question, both school and workshop? Seemed to be a consensus for that If virtual, maybe 1/2 day program and twice as long, two weeks long, one week for school and other for worksh itop. When? Maybe after Mid-West Relativity meeting...usually in the Fall---last year's was in October. Roland will check on LIGO meetings, etc, and put out a survey for which weeks are good. Some thoughts that summer would be good too. Also ideas for Program Items please mention them here and mailing list. https://sites.google.com/nd.edu/mwrm-2020/meetings https://sites.google.com/nd.edu/mwrm-2020/ was 22 October 2020 at Notre Dame. * [https://www.einsteintoolkit.org/tools/unanswered.php unanswered question on mailing list] / Script for Unanswered is a bit problematic, so not all are real. The real is "CarpetMask and SphericalSurface (Gabriele Bozzola)" . Steve will take a look and respond. * [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] #2386 CCTK_LOOP3_INT and friends broken..., Miguel Z will have a look at the bug fix and pull request. He says fix works for him. https://bitbucket.org/einsteintoolkit/tickets/issues/2386/cctk_loop3_int-and-friends-broken-for * Any other business? Steve, Funded proposal had a scientific gateway ifor the ETK, could be for teaching purposes, could be other. Web portal? Chat bot? Steve wants to know what would we find useful for teaching or other. Bring up next week. * Chairs and Minute takers Feb 18th Chair Peter D, Minutes Maria BH Feb 25th Chair Steve B, Minutes Atul K -- ============================== 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
