[Einstein Toolkit] #542: Remove thorn CactusArchive/ADM from thorn list

#542: Remove thorn CactusArchive/ADM from thorn list -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: task | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Remove thorn CactusArchive/ADM from thorn list. This thorn is outdated, and we should updated out test cases instead. It also takes a long time and a lot of memory to compile. If we want an ADM formulation (which is doubtful since we don't use it ourselves), we should implement one via Kranc. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/542> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#626: Recovery fails in AHFinderDirect RecoverML with out-of-bounds assertion in CarpetLib --------------------+------------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: ET_2011_10 Component: Carpet | Version: Keywords: | --------------------+------------------------------------------------------- when trying to recover in AHFinderDirect's RecoverML test (parfiles attached) I get: {{{ cactus_et: /home/rhaas/ET_2011_10/arrangements/Carpet/CarpetLib/src/th.hh:79: double th::get_time(int, int, int) const: Assertion `tl>=0 and tl<timelevels' failed. }}} After some debuggin I traced this down to the metric which in CarpetIOHDF5/src/Input.cc:762 is reported (by gf->timelevels (ml, rl)) to have three timelevels. However the timelevels member of gf->t (a th) gives the number of timelevels as two {{{ gf->t.timelevels $28 = 2 }}} Since timelevels is new in Carpet/Hg my suspicion would be that it is not properly updated when gf->set_timelevels is called (the comments in th.hh seem to indicated that it is assumed to be const which seems odd given that ggf::set_timelevels exists). I don't understand enough of Carpet to fix or further debug this. Marking its as major and release relevant in case it is actually a Carpet bug. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/626> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #963: Improve McLachlan accuracy

#963: Improve McLachlan accuracy -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- James van Meter provided me with an optimised version of McLachlan. He states: 1. You are not taking full advantage of the chi=exp(-2phi) variable. There are several terms you divide by chi or chi^2 in expressions with overall factors exp(-4phi). I rewrote the BSSN equations to make these cancellations before coding. So where you have an expression of the form chi^2(A+B/chi^2), I have chi^2A+B. This gives a slight but noticeable advantage in both accuracy and performance. 2. I added Hamiltonian-constraint-damping terms due to Duez et al. These terms don't seem to be well-known but they are effective. 3. I added a Gamma-constraint-damping term due to Yo et al. 4. I enforce det(g)=1. I have not tested this new version yet, but James suggests to include it into the Einstein Toolkit. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/963> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #605: Simfactory does not find the right 'path' for symlinked cactus directories

#605: Simfactory does not find the right 'path' for symlinked cactus directories ------------------------+--------------------------------------------------- Reporter: knarf | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: ET_2011_10 Component: SimFactory | Version: development version Keywords: | ------------------------+--------------------------------------------------- Simfactory currently does not detect the 'right' path to a Cactus sourcetree if this is from within a symlink, e.g. Cactus -> /mnt/data/Cactus. This is because while `pwd` returns '/home/user/Cactus', simfactory uses a wrapper to the C-library getcwd(), which dereferences symlinks. Simfactory then gets '/mnt/data/Cactus' and tries to use this path on remote machines when syncing - which of course does not work. The attached patch fixes this by using os.environ.get("PWD") and, if this is not defined, using os.getcwd() as workaround. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/605> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
