Cactus Building Issue
by Rodriguez, Shanshan 15 Feb '19

15 Feb '19

Hello, I’m a new user of ETK and trying to follow the tutorial to set up Cactus. I ran into this problem building Cactus and hope you could help me resolve it. Here is the commend I’m stuck at: %cd $cactus_dir !time ./simfactory/bin/sim build -j2 --thornlist=thornlists/einsteintoolkit.th<http://einsteintoolkit.th> Where I got an error message at the end: checking whether the C compiler (gcc-mp-7 -g -std=c11 -lgfortran) works... no configure: error: installation or configuration problem: C compiler cannot create executables (see configs/<configname>/config-data/config.log for details). Error reconfiguring sim-config make: *** [sim-config] Error 2 I’m attaching the config, log file here. Could you suggest what I should do to fix this? Thank you so much!!

Choose Self-defined Output Results Directory
by Steve Hawk 15 Feb '19

15 Feb '19

Hello: As a newer to Einstein Toolkit, I have successfully finished and executed the example file in the server following the link: https://github.com/nds-org/jupyter-et/blob/master/CactusTutorial.ipynb. But I have a question about deciding the simulation output directory，how can l give the self-defined output directory for storing the simulation results. Is there any files contents or commands inside ET that could define the output directory by myself, or any documentations clarifying how the Einstein Toolkit decide the IO directory? Maybe it is a simple question, but I really don’t want to mess the common folders up too much, since I need to work out some simulations about NR in the group’s server. Thanks a lot ! Best regards, Hawk Steve

Steve, Roland and Sam worked in the presync code and now have some test suites using mesh refinement working. This will not go into this release but possible the one after. ET tutorial server volunteers needed * We are looking for person(s) interested in creating a HTML page for signup for the tutorial server which can be started as a copy of the new user registration page https://einsteintoolkit.org/join.html * A second page would be needed to serve as a webhook for bitbucket ticket creation / changes: https://bitbucket.org/einsteintoolkit/tickets/issues/2225/bitbucket-does-no… * If interested please contact the maintainers maintainers(a)einsteintoolkit.org unanswered question on mailing list / open tickets sorted by update time * one unanswered question: http://lists.einsteintoolkit.org/pipermail/users/2019-February/006753.html Yours, Roland -- My email is as private as my paper mail.

by 林家暉 13 Feb '19

13 Feb '19

Hello, I have a problem about the gallery example of binary neutron star (https://einsteintoolkit.org/gallery/bns/index.html). Is it possible to evolve and output some parameters like entropy , temperature and electron fraction ? Is so , how should I modify the parameter file (NsNsToHMNS.par) ? Thank you. Best regards, Chia-Hui

Present: Roland, Peter, Sam, Steve, Antoni, Zach SSL certificates for svn.cactuscode.org: * should be fixed later today ET release planning: * BNS galler example ** no update yet * WVU_Analysis status ** in repo and compiling ** test suite still missing * Proca / Lean status ** Peter made progress reviewing responses to original review ** tests have been added, tests use Lean, Peter sees failures using Lean on his laptop ** should finish 2nd round of review today or tomorrow Release relevant tickets: ** https://bitbucket.org/einsteintoolkit/tickets/issues/2219/fix-sqrt-for-avx5… should be taken care of Bitbucket transition: * does no longer sent emails to ET mailing list * table of tickets (https://bitbucket.org/einsteintoolkit/tickets/issues) gives only very little room to ticket title, would be nice to be able to reserve more space. Bitbucket allows some customization https://developer.atlassian.com/blog/2016/02/6-secret-bitbucket-features/#c… but no one on the call has experience how to do so. Google also finds https://bitbucket.org/site/master/issues/7139/customize-able-column-headers… and https://bitbucket.org/site/master/issues/11883/issues-list-is-unreadable-if… . github transition: * all branches have been moved to github Zach reported change in behaviour when adding / removing thorns from thornlist: * https://bitbucket.org/einsteintoolkit/tickets/issues/2224 * Steve will look into it since it seems piraha related US ET workshop at RIT: * announced on hyperspace * add link to ET website Yours, Roland -- My email is as private as my paper mail.

by Rodriguez, Shanshan 05 Feb '19

05 Feb '19

Good morning, As I was following the new user Tutorial and trying to request access following this link: https://www.einsteintoolkit.nationaldataservice.org it doesn’t seem to be able to connect with the server. Would you please advise me if there is another way to request a queen bee account?
