Parameter file error with EHFinder
by Maitraya Bhattacharyya 08 Feb '17

08 Feb '17

Dear all, I am trying to run the EHFinder thorns on some numerical data stored at hdf files in a directory. However, running the parameter file returns an error: WARNING level 0 from host maitraya-Lenovo-Y50-70 process 0 while executing schedule bin (none), routine (no thorn)::(no routine) in thorn Cactus, file /home/maitraya/Cactus/src/main/SetParams.c:93: -> CCTKi_SetParameter: Error at line 21 in parameter file /home/maitraya/simulations/EHF/output-0000/EHF.par while activating thorns Since I am new, I may have written the parameter file incorrectly. The contents of the parameter file are below: ActiveThorns = "IOUtil ioascii iobasic" # IO parameters # IO::recover_dir = "/home/maitraya/Desktop/David/" ActiveThorns = "cartgrid3d" # grid parameters CartGrid3D::type = "coordbase" CartGrid3D::domain = "full" CartGrid3D::avoid_origin = "no" CoordBase::xmin = -5.9 CoordBase::ymin = -5.9 CoordBase::zmin = -5.9 CoordBase::xmax = 5.9 CoordBase::ymax = 5.9 CoordBase::zmax = 5.9 CoordBase::dx = 0.40689655172413808 CoordBase::dy = 0.40689655172413808 CoordBase::dz = 0.40689655172413808 ActiveThorns = "EHFinder" # EHFinder parameters ehfinder::shell_width = 1.8 ehfinder::mode = normal ehfinder::initial_f[0] = "sphere" ehfinder::initial_rad[0] = 5.0 IOBasic::outScalar_vars = " ehfinder::f ehfinder::eh_mask" IOASCII::out1D_vars = " ehfinder::f ehfinder::eh_mask ehfinder::eh_area ehfinder::eh_centroid_x ehfinder::eh_centroid_y ehfinder::eh_centroid_z ehfinder::eh_circ_eq ehfinder::eh_circ_pol " IOBasic::outInfo_vars = "ehfinder::f " Please tell me what I am doing wrong ?

new web page design
by Frank Loeffler 07 Feb '17

07 Feb '17

Hi The current Einstein Toolkit web pages at http://einsteintoolkit.org/ are about to be replaced with a newer design. Some content changes might go with that, but a strong emphasis is on the design change. Feel free to suggest content improvements, but please don't mix them with the design change. The new pages can currently be previewed at http://einsteintoolkit.org/new/index.html We would like to get feedback before making the switch. In particular, we are interested in experiences with all kinds of browsers and/or devices and screen sizes. If you think you've encountered a bug that relates to the layout, a screen-shot might be the best way to show what you see. You can view the source behind the web pages within the bitbucket repository https://bitbucket.org/einsteintoolkit/www (and separate, due to its size): https://bitbucket.org/einsteintoolkit/seminars If you are developer, you should have write permissions. Reporting something like a typo probably takes longer than fixing it there. If you like to make larger changes and feel unsure about them, feel free to open a pull request and a ticket. We will discuss received feedback at the next Einstein Toolkit call (Monday next week; 6th of February). Depending how things go, that might be as early as the new version goes live. Frank Löffler PS: Don't report the crappy look of images in Microsoft Edge (probably all IE as well). That's due to the crappy image interpolation MS uses, and there isn't a good way to deal with that other than using a decent browser.

Cactus Core Usage on HPC Cluster
by Gwyneth Allwright 06 Feb '17

06 Feb '17

Hi All, I'm trying to get the Einstein Toolkit installed on an HPC cluster running SLES. The trouble is that Cactus tries to use all the available processors even when I specify a smaller number (by setting ppn in my PBS script). As a test, I tried running the compilation with a parameter file that required about 5 GB of RAM. In my PBS script, I set nodes=1 and ppn=3, and then ran using openmpi-1.10.1: mpirun -hostfile $PBS_NODEFILE <ET exe> <parameter file> This resulted in the simulation running on all 24 available processors, even though I'd only requested 3. Since PBS and MPI are integrated, I was told that using -np with mpirun wouldn't help. Does anyone know how to address this issue? Thanks, Gwyneth

Present: Frank, Roland, Josh, Ian, Peter, Gabrielle, Bhavesh Failing master build: * https://trac.einsteintoolkit.org/ticket/1939 * either approve this or revert all changes * ask to review by today Failing tests in release: * due to compiler/cpu issues * not quite clear which versions are affected * happens on both the Jenkins slaves as well as some clusters * on clusters we see multiple intel compiler version failing (15 seems susceptible). Seems a compiler bug since printf() seems to help. * this shows up in the ML constraints in RotatingSymmetry90/180 * Roland to check GRHydro checks * Peter to check on ML constraints Website: * comments must be submitted by next Monday, after which the new website will go online presync work: * currently have a wavetoy working * Steve asks for feedback * https://github.com/stevenrbrandt/PresyncWave which contains instructions Yours, Roland -- My email is as private as my paper mail. I therefore support encrypting and signing email messages. Get my PGP key from http://keys.gnupg.net.

Connecting to einstein toolkit calls
by Khamesra, Bhavesh 06 Feb '17

06 Feb '17

Hi, I am Bhavesh, a graduate student working with Prof. Laguna at Georgia Tech. I wanted to attend the weekly calls of einstein toolkit. Could someone guide me about this process? I am subscribed to einstein toolkit - users mailing list but did not get any email about the link to the hangout call. Is there a different mailing list for the calls? Thanks Bhavesh ............................. Bhavesh Khamesra Graduate Student Centre of Relativistic Astrophysics Georgia Institute of Technology

tutorial for new users, edits, question about plots
by Bill Gabella 01 Feb '17

01 Feb '17

I tried to edit the https://docs.einsteintoolkit.org/et-docs/Tutorial_for_New_Users anonymously (and maybe it worked, do we want it to work with anonymous edits?) But just in case it reverts, I changed the text p 'hydrobas::rho.maximum.asc' u 2:3 w lp to p 'hydrobase-rho.maximum.asc' u 2:3 w lp and similarly lower down p 'admbase::lapse.minimum.asc' u 2:3 w lp to p 'admbase-lapse.minimum.asc' u 2:3 w lp I have output files with the '-' in them and not '::' . Also using the static_tov.par that comes with ETK_2016_11 in /repos/einsteinexamples/par/static_tov.par and my plots look very different than the tutorial plots...but caution, I am new to ETK! hydrobase-rho.maximum.asc plot Image:rho_of_time.png and admbase-lapse.minium.asc plot Image:Lapse_of_time.png On the left are my ETK runs of static_tov.par and on the right are the ones from the new user tutorial. My run "looks" successful in that I have no errors and it ran to the end of the time, 1000. I have many warnings in the output file, but mostly the seem benign. So THE question here, are my plots right or are the tutorials? And could it be the static_tov.par in the ETK_2016_11 is different than used on the tutorial? Thanks for future help. Also just practicing posting to the list:) bill e.g. -- ===================================== William Gabella Research Assistant Professor Department of Physics and Astronomy Vanderbilt University Nashville, TN USA b.gabella(a)vanderbilt.edu (o) 615-343-2713

EHFinder
by Maitraya Bhattacharyya 01 Feb '17

01 Feb '17

Dear all, I had some NR data which I could reformat and pack into the lapse, shift and spatial metric in separate hdf files. I would want to run EHFinder on them and find the event horizon. I need some help writing a parameter file which reads data from a particular directory and runs EHFinder on them. Any help is appreciated. Maitraya.

Present: Frank, Roland, Ian, Gabrielle Allen, Vassili, Steve ET website: * online at http://einsteintoolkit.org/new/ * can be edited via git repo at https://bitbucket.org/einsteintoolkit/www/src which all maintainers should be able to edit * sub-menu button in About maybe too small, better to have a landing like page as for "Documentation" * find a middle ground between all on one page and very many tiny pages * needs to be tested on more common browsers, suggest at least Safari/OSX, Firefox, Chrome, Edge/Internet Explorer, mobile broswers on both IOS and Android both phone and tablets * contact someone with design experience about colour scheme Read/write driven SYNC: * Steve worked on this and has sent out a link: https://github.com/stevenrbrandt/PresyncWave * works for a wavetoy, not yet clear if prolongation would work or if works for production code * the README file should contain usage instructions * feedback would be appreciated Simfactory machine files/options/submit/run scripts * treat as documentation, ie no review is required but use your own good judgement Yours, Roland -- My email is as private as my paper mail.
