Hello all,
minutes:
* Sam Cupp reported on timing tests for Minkowsky using Z4c vs. McLachlan. Showed total time graph. Using gcc, which produces somewhat sub-optimal code (still true in gcc 11, but fixed in master branch). * Total tme plot included (timed with time). Should be using CCTK_EVOL+CCTK_PRESTEP etc. bin timer.
* Jay tried Balsara1 tests, plotted exact solution over simulation output. * graphs do not line up (more structure in exact solution), in particualr exact solution would display non-zero vy but we have zero vy (both in ID and during evolution). * test is technically magnetised but we left out magnetic field, need a test with zero magnetic field * suggest using Sod test which is non-magnetised, exact solution may be (not quite clear) in Marti&Müller https://link.springer.com/article/10.1007/lrca-2015-3 or in Bruno'scode as long as one sets up ID with zero magnetic field * Lorenzo had some issue getting new code to download, Erik helped setting up the required symbolic links from repo checkout to arrangements * continued cleaning up code, with Lorenzo typing * noticed that code is much cleaner than last time already * Steve will set up DeepBayou accoutns for all that ask so that we have a shared GPU code
Yours, Roland
