The visualization result generated by file gxx_x is attached below. What is this indicating and what is along x-axis and y-axis. Kindly reply me as soon as possible.

Einstein Toolkit Workshop Dates
by Ferguson, Deborah L 31 Jan '18

31 Jan '18

All, Georgia Tech is hosting the Einstein Toolkit Workshop this year, and we are working on finalizing the dates. Below, I have linked to a when2meet poll for everyone to indicate their availability. All the dates are in June and we are aiming to have a 3 day workshop. We would like to finalize the dates before next Monday, so the final day to vote will be Sunday, February 4. https://www.when2meet.com/?6644007-rVgmz Thank you, Deborah Ferguson ----------------------------------------- Deborah Ferguson Graduate Student Georgia Institute of Technology Center for Relativistic Astrophysics Boggs 1-66

compile problems on OSX High Sierra using homebrew
by Roland Haas 29 Jan '18

29 Jan '18

Hello all, I am getting odd compile errors on OSX using osx-homebrew.cfg (in master). There seem to be two different errors right now: * _mm_add_ps is not found (even though xmmintrin.h exists) * ranlib (it uses XCode's) complains about the .a files that it claims have no symbols. Forcing the use of ranlib from homebrew does not show the error but then I need to hard-code the full path since homebrew does not put ranlib in /usr/local/bin I attach the make output (both types of errors are visible at the end). A side node: to have remote commands work on OSX (ie remote compiling *on* my OSX laptop not from it) only works if I add "source /etc/profile" to my envsetup (otherwise /usr/local/bin is not added to $PATH it seems). Has anyone seen these types of errors before and / or could point me to a "canonical" location for ranlib on OSX (rather than /usr/local/Cellar/binutils/2.30/x86_64-apple-darwin17.3.0/bin/ranlib)?

meeting minutes for 2018-01-29
by Roland Haas 29 Jan '18

29 Jan '18

Present: Roland, Antoni Ramos Buades, Eloisa, Erik, Ian, Jim, Sam, Steve, Peter, Yosef, Bhavesh, Bill, Carlos, Gabrielle, Muricia Suarez, Roberto de Pietri, Qian, two anonymous callers Invitation to join cosmo working groups * if interested, please join the mailing list as outlined in the email by Helvi at: http://lists.einsteintoolkit.org/pipermail/users/2018-January/006021.html Failing tests in PITTNullCode: * Yosef tracked it down to a compiler bug. The only affected code is the test, regular code in the thorn does not use the failing combination of operations. A bug report has been filed with the gcc developers * would like to find out which versions are affected * will follow Yosef's suggestion and remove the test Release status: * test are in the process of running on clusters * have to find out (again) how to populate http://einsteintoolkit.org/testsuite_results/index.php * had release status meeting on Friday and could clarify most issues * details are here: https://docs.einsteintoolkit.org/et-docs/Release_Details * Ian created tickets for the otustanding tasks (marked with the milestone) in the trac system * code name "Tesla" OpenMP scaling: * Jim ran openmp-tasks version on Stamped2 Skylake * running on larger number of cores (~24 nodes) one sees an improved runspeed using the task based prolongation compared to either the old code or the new code with the options turned off * this test used 11 reflevels and fairly high resolution * Erik points out the importance of thread binding in Cactus which requires the SystemTopology thorn. Jim will re-run with that thorn active (~256 iterations is enough). Should also post the stdout files where Carpet lists thread binding results ET US meeting at GT: * dates have still to be finalized Yours, Roland -- My email is as private as my paper mail.

Re: [Users] questions about compilation

Hello Chia-Hui, this looks to me as if you are either not using the correct allocation or are out of allocation time. Given that salloc worked for you I would think is is the former. Please check your simfactory/etc/defs.local.ini file in the [edison] section to make sure that you have an allocation = XXX line where XXX is your allocation. You can also check the SubmitScript (=SLURM) script used to see exactly what simfactory passed to sbatch. The exact location is in the screen output in the "Submit script:" line. Yours, Roland > Dear Roland and whom it may concern, > Before I set the submission as an interactive job which means I use the command : > salloc -N 2 -p debug -L SCRATCH > as I ran the example code. > Recently I tried to set it as a batch job , so the command becomes: > sbatch @SCRIPTFILE@ > However I met another error which seems the NIM information for me is not available as showed in the attached file. > I am wondering whether it is related to the previous problem which we have discussed or there is something I was missing. > > Best regards, > Chia-Hui Lin > [cid:96df1161-586b-41e0-9ab7-a71b981bac7c] > ________________________________ > 寄件者: ian.hinder(a)aei.mpg.de <ian.hinder(a)aei.mpg.de> > 寄件日期: 2018年1月23日下午 04:17:35 > 收件者: Roland Haas > 副本: Einstein Toolkit Users; 林家暉 > 主旨: Re: [Users] questions about compilation > > > > On 21 Jan 2018, at 17:16, Roland Haas <rhaas(a)illinois.edu<mailto:rhaas@illinois.edu>> wrote: > > Hello Ian, > > Shouldn't these changes be backported to the current release? > Sure.
