question on GRHydro atmosphere mask
by Luciano Combi 14 Dec '23

14 Dec '23

Hello people. I've been using (a version of) GRHydro for a while and I was wondering if you know what motivated the use of an atmosphere mask. I understand that this is useful to set atmosphere states between mesh refinement levels, but I'd like to know if you've seen problems before just resetting locally to atmosphere. Thanks!!

Present: Zach, Steve, Vaishak Prasad, Sam, Leo Chair: Sam Minutes: Steve Checked: http://einsteintoolkit.org/testsuite_results/index.php Roland says we cannot compile on MacOS. Too many problems. JupyterET - needs to rebuild and push to dockerhub Only Roland or Steve can do that. Ready for Zenodo (Steve will do) Gallery exmaples Deborah has a PR for the website repo for her changes The BNS has been run, but analysis is not yet done TOV is being done by Peter Unanswered emails Question about atmosphere mask, need to ask original authors. Simfactory2 website doc issue updated NSIMD needs some testing and investigation Next meeting: Jan 11

Trouble Building Cactus Thorns on Mac and on Expanse
by Joe Hellmers 07 Dec '23

07 Dec '23

Hello, I’d like to use Hyrdro_RNSID in order to generate a initial data for a rotating neutron star, but I’m having some difficulties building the Cactus thorns. Initially I’m just trying to build all of them. When I try to build on my Mac using the latest GNU compilers from Brew, I get a message that my compiler doesn’t support std c11. The version of gcc installed is Apple clang version 15.0.0 (clang-1500.0.40.1), whatever that gcc version that ends up being. If I use the gcc from the MESA SDK, (version 12.2.0) I get the same message. So, I switched to try it on the SDSC Expanse cluster, and at least I don’t get that problem, but I do end of having an issue that it is looking for some Slurm include files from a version that isn’t on expanse any more. Specifically it is looking under /cm/shared/apps/slurm/20.02.3/ but Expanse now has /cm/shared/apps/slurm/21.08.8. So I have a few questions 1) How can I just build what I need for Hydro_RNSID? 2) What can I do about building on my Mac? 3) Where can I change the configuration of my build so that it refers to the correct Slurm version when building on Expanse? Thanks! Joe Hellmers San Diego State University- Physics Dept.
