Re: [Users] [ET Trac] #2285: Add the Self-Force code to the ET
by Peter Diener 25 Sep '19

25 Sep '19

When we asked for reviewers on the ET call, I mentioned that the code is still private on the bit buckets and that people interested in looking at the code should contact me so I could grant permissions. The reason being that I'm still finishing up the code test paper. If you send me your bitbucket user name, I can add you.

I am trying to install Einstein ToolKit on my laptop following these instructions: https://nbviewer.jupyter.org/github/nds-org/jupyter-et/blob/master/CactusTu… but I run into errors when using the (last) command: ./simfactory/bin/sim build --mdbkey make'make -j2' --thornlist ../einsteintoolkit.th it seems that the computer cannot find the file ~/Cactus/configs/sim/config-data/make.thornlist what do I do?

Question about GW150914 and other simulations
by 黎旭翔 19 Sep '19

19 Sep '19

Dear friends, We are trying to use those examples listed on the website to test if it works on our HPC. https://einsteintoolkit.org/gallery.html <https://einsteintoolkit.org/gallery.html> It goes well with a simple tov equation, which takes 2-5 min. But when we use it to simulate GW150914 BH merger or solve tov equation with high precision and long time, it seems that it will stop at an iteration point without any further output, even an error. What really confuses us is that for different tests it stops at different points. Could you please help us find out what goes wrong with the simulation? I will attach the log.txt and parameter files to this mail. Thanks for your time! Here we used a partition with 144 nodes. Sometimes with a specific —procs and —num-threads number in the shell file, the simulation finished successfully. In other time it came across the problem above. In the two neutron star output files, the job stoped at two different iteration points, and was cancelled due to time out or by hand. Yours, Xuxiang ————————————————————————————————————————————————————————— Xuxiang Li, School of Physics, Peking University Email: jukcoeng(a)pku.edu.cn <mailto:jukcoeng@pku.edu.cn>

make <config>-utils failing with "RNS" error (ET_2019_03)
by Bernard Kelly 19 Sep '19

19 Sep '19

Hi. I have a working recent release of the ET (2019_03) that compiles & runs fine, but which fails when I try to build the associated utilities: --------------------- >make sim-utils Building utilities for sim make[1]: *** No rule to make target '/nobackupp2/bjkelly1/codes/Cactus/exe/sim/RNS', needed by 'utils'. Stop. Makefile:872: recipe for target 'sim-utils' failed --------------------- I'm left with about 50% of the utilities --- basically everything through "hdf5tobinary_slicer". But "hwloc-assembler" and all the other hwloc-related utilities haven't built. I have the ET_2018_03 release on the same machine, and that builds both the primary executable *and* all the utilities with no issues, even though the compilation options are identical between the two. Possibly relevant: (1) I don't know what the RNS refers to, but I am including the thorn GSFC_GRMHD_Initial/RNSID in my configuration (both old and new). (2) One difference between old and new configurations is that I'm not compiling CactusUtils/SystemTopology, as that gives me link-time errors with hwloc.

meeting minutes for 2019-09-19
by Haas, Roland 19 Sep '19

19 Sep '19

Present: Bill, Chris, Helvi, Maria, Peter, Roland, Steve, Toni. Yosef, Yu Liu, Zach ET release: * Steve is reviewing Peter's self-force code, may open up ticket system in code repo * no one assigned yet to review Zach's Fishbone-Moncrief disk code, needs volunteer * DOI: proceed as planned * timeline for the release: freeze next week * name: Maria Goeppert Mayer (Physicist, Nobel prize 1963, 1972) KCL workshop review: * about 60 participants, 40 of them were new or beginning users * most slides are available on website, tutorials are in slack channel * video recordings of talks and lectures should be available in 1-2 weeks of time on Youtube * diverse topics from compact object mergers to exotic matter and mathematical topics * had a presentation by Niels Warburton on black hole perturbation theory * had fruitful discussion with GRChombo developers, plan to do code comparison project in the future * lessons learned: time for dedicated discussions was a bit short Unanswered questions: * for the manual topology issue Yosef will submit the patch that made things work for him, so that the issue is clearly spelled out * Steve provided some comments on http://lists.einsteintoolkit.org/pipermail/users/2019-August/006995.html based on his own experience with this, Yosef will forward to Carlos * http://lists.einsteintoolkit.org/pipermail/users/2019-September/007011.html * Steve suspects that http://lists.einsteintoolkit.org/pipermail/users/2019-September/007020.html may be caused by running out of memory and paging NRPy+ based BSSN code: * Zach has started to write a McLachlan equivalent BSSN code in NRPy+, and is making some progress as of the beginning of this week. Code is based on Lean so far. Will chat with Helvi about this. https://nbviewer.jupyter.org/github/zachetienne/nrpytutorial/blob/master/Tu… Gallery examples: * runners will be on DOI for this release only * BBH: Helvi et al. * Poisson: Helvi et al. * scalar wave: Helvi et al. * TOV: Helvi et al. * BNS: still an issue, originally assigned to Peter but would need help, will need to find an old ET release that produces the output shows on the gallery. Maria will try and help out with this. Ticket is: https://bitbucket.org/einsteintoolkit/tickets/issues/2119 Next week's call will be chaired by: Helvi Yours, Roland -- My email is as private as my paper mail.

Re: [Users] HDF5 and submission/runtime issues on a PBS cluster
by Haas, Roland 19 Sep '19

19 Sep '19

Hello Vaishak, as usual, I would suggest addressing the mailing list. Would you mind if I forward this email to the list? Your point 3 sounds like either an incorrectly set-up cluster or (if this is a "private" cluster) missing passwordless ssh keys. I would contact your cluster administrators and show them the output of trying to run something like: mpirun -np 64 /usr/bin/hostname which tries to start 64 copies of the "hostname" command. Make sure that 64 is more cores than a single node can provide. Alternatively you can try and fix this yourself following for example https://www.open-mpi.org/faq/?category=rsh#ssh-keys but do leave the password blank (this implies you should only use this key-pair on the cluster and not do log into the cluster from the outside). Yours, Roland > Dear Sir, > > Thankyou very much for you reply. I will add the additional lines to > LDFLAGS and try. > > What do you think about the other issue point 3 in the document ?
