How to set adaptive refinement.

Hello all, When I doing the simulation Hydro_RNSID in Einstein Toolkit. I met some problems: WARNING[L1,P0] (GRHydro): Con2Prim failed; stopping the code. WARNING[L1,P0] (GRHydro): Even with mesh refinement, this point is not restricted from a finer level, so this is really an error WARNING[L1,P0] (GRHydro): on carpet reflevel: 1 WARNING[L1,P0] (GRHydro): xyz location: 0.000000 -6.000000 0.000000 WARNING[L1,P0] (GRHydro): radius: 6.000000 WARNING[L1,P0] (GRHydro): hydro_excision_mask, C2Pfailed: 0 1.000000 WARNING[L1,P0] (GRHydro): rho eps press w_lorentz: 0.1057347E-05 0.1857035 0.1963532E-06 1.047789 WARNING[L1,P0] (GRHydro): velocities: 0.2045605 -0.4772050E-01 0.9116232E-16 WARNING[L1,P0] (GRHydro): dens tau: 0.3259242E-05 0.8464639E-06 WARNING[L1,P0] (GRHydro): scon: 0.1949336E-05 -0.3921220E-06 0.8515884E-21 WARNING[L1,P0] (GRHydro): 3-metric: 2.054383 0.8422013E-01 0.3666352E-20 2.115545 -0.1509363E-20 1.994599 WARNING[L1,P0] (GRHydro): lapse, shift: 0.6504332 -0.9400928E-01 -0.2831831E-01 -0.3942654E-21 WARNING level 0 from host lyh-Lenovo process 0 while executing schedule bin CCTK_POSTSTEP, routine GRHydro::check_GRHydro_C2P_failed in thorn GRHydro, file GRHydro_Con2Prim.F90:1847: -> Aborting.

question about Cactus::cctk_final_time
by 黃世杰 24 Sep '18

24 Sep '18

i have runned the simulation of binary neutron stars in the gallery example, and at first, the set of Cactus::cctk_final_time(in the parameters file --"NsNsToHMNS.par") is 2500, but i want to prolong it, so i modify the Cactus::cctk_final_time from 2500 to 7000, and the parameterfiles at the ~/Cactus/par/ and /scratch2/scratchdirs/jie9/simulations/NsNsToHMNS/output-000X/ I both modify, but the simulation still stop when the time come to 2500, how could i do ? Best, jie

meeting minutes for 2018-08-27
by Roland Haas 04 Sep '18

04 Sep '18

Present: Steve, Roland, Yosef, Zach, Helvi, Sam, Bhavesh, Peter, Patrick Nelson, Bill Working group updates: * Perforrmance optimization: nothing to report * Education: nothing to report * Cosmoparticle: nothing to report * IllinoisGRMHD: updates are on the wiki page, https://docs.google.com/presentation/d/1ZBc8VQGZm3Gj3fu5TO75TW8swc4VETxnKy1… Gallery examples for next release: * BBH: comparison between current code and gallery data in Zenodo, results are pretty close. Plots are here http://lists.einsteintoolkit.org/pipermail/users/2018-August/006471.html * poisson: Roland updated code, with this he can reproduce the plots, updated the website * BNS: Peter found out that change of using EOS_Omni to compute quantities cause most of the initial differences, after merger there are still differences. So far no input from Frank or Roberto, Peter will contact them directly. Reviews: * WVUDiagnostics: no progress, want testsuites. Push to next release unless we have tests soon. * GiRaFFE: main thorn reviewed, most of GiRaFFE_Food, Zach and Roland to prioritize this request over others * Lean: Erik to review, likely not before the release * Proca: Peter made some progress, will continue to push it this week Documentation: * would like some documentation explaining how to set up checkpoint / restart IllinoisGRMHD robustness: * Zach reduced the maximum allowed speed to have a max. speed less than c_light * finds that robustness is greatly increased if one uses 3rd order Lagrange interpolator for IllinoisGRMHD variables. There is a pull request for such an operator: https://trac.einsteintoolkit.org/ticket/2189 Testsuites: * remove MPG machines: draco, minerva, hydra are MPG machines. Wolfgang said he could maybe run on one of them, if not then we will remove them * Peter will run smic * Marconi: a machine in Italy, Roberto de Pietri, Eloisa had access, if they cannot run, then we should remove them Moving website to github: * may be difficult to move due to multiple repos being linked up * some pages use php and cgi which are not straightfoward to run from github * currently have docker image that makes the server much more self-contained than before, docker image is here: Working group calls: * IllinoisGRMHD on Wednesday 11:00AM US Eastern Time * Performance optimization on Friday 12pm US Central time Yours, Roland -- My email is as private as my paper mail.

Issues with Downloading/Installing the tool kit

I’m loading the toolkit on the Comet Supercomputer at the San Diego Super Computing facility (SDSC).

Fwd: Re: relative times in modified between search on trac

Brandt <sbrandt(a)cct.lsu.edu> To: rhaas(a)ncsa.illinois.edu I think that not allowing that string is a "feature" of the new Trac.

error while loading shared libraries
by Hamilton, Maria 29 Aug '18

29 Aug '18

Hello, I am trying to get ET up and running on BigGreen, an OpenHPC cluster, Slurm as workload manager. http://biggreen.marshall.edu/ganglia/?r=2hr&cs=&ce=&m=load_one&s=by+name&c=… It compiled fine with mpich, using the configuration file provided within Cactus for CentOS 7. However, when running, I have problems with the shared libraries: liblapack.so.3, libhdfhl_fortran.so.8. I could export the library paths when I find where they are, but I was wondering if there is a simpler work around this. What do I need to do in order to be able to work with static libraries? thanks, Maria _______________________ Dr. Maria C.
