[Einstein Toolkit] #1201: Incorrect dtshift in Exact with shift_add_{x, y, z} parameters

#1201: Incorrect dtshift in Exact with shift_add_{x,y,z} parameters -----------------------------------+---------------------------------------- Reporter: barry.wardell | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The Exact thorn has shift_add_{x,y,z} parameters for adding a constant to the shift. Considering these as a coordinate transformation using a vector v^i = [shift_add_x, shift_add_y, shift_add_z], such a transformation should affect both the shift and its time derivative. This is because the time derivative in the new coordinates differs from the time derivative in the old coordinates by a term v^j d(beta^i)/dx^j. This is correctly implemented as a 4D coordinate transformation in the EinsteinExact thorns and I have verified that the difference relative to the Exact thorn is given by this missing term. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1201> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1690: The test system should treat a nonzero exit code from Cactus as a failure

#1690: The test system should treat a nonzero exit code from Cactus as a failure --------------------+------------------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- The test system seems to ignore the fact that Cactus exits with a nonzero exit code. It displays Cactus exited with error code 1 Please check the logfile... No files created in test directory Success: 0 files identical And in the summary at the end, it treats this as a passing test. In this case, there were no test reference files and no files output, because the test (by design) does not produce any data, it just aborts if the test fails. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1690> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

Ie right now it would be identical to 2016_05. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1949> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1658: ExternalLibraries/pciutils does not compile on Mac OS --------------------+------------------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- When I try to compile ExternalLibraries/pciutils on Mac OS, I get {{{ lspci.c:919:29: error: expected ')' puts("lspci version " PCIUTILS_VERSION); ^ ./pciutils.h:18:26: note: expanded from macro 'PCIUTILS_VERSION' #define PCIUTILS_VERSION PCILIB_VERSION ^ lspci.c:919:11: note: to match this '(' puts("lspci version " PCIUTILS_VERSION); }}} This is with the osx-mountain-lion-macports-gcc.cfg optionlist, and "gcc- mp-4.6 (MacPorts gcc46 4.6.4_3) 4.6.4". I have to disable this thorn in my thornlist (or machine definition file) to compile the ET. This means that the ET will not compile out of the box on Mac OS. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1658> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1906: CarpetRegrid2: possible off-by-one error when using regrid_every parameter

#1906: CarpetRegrid2: possible off-by-one error when using regrid_every parameter ---------------------------+------------------------------------------------ Reporter: bmundim | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: CarpetRegrid2 | ---------------------------+------------------------------------------------ I was working on a par file for a quick regridding test and found out an unexpected behaviour regarding regridding. Basically I want a par file with a few iterations such that it adds a refinement level every 4 iterations for example. I set the following parameters then: {{{ CarpetRegrid2::add_levels_automatically = "yes" CarpetRegrid2::regrid_every = 4 }}} for a grid structure as such: {{{ Cactus::cctk_itlast = 10 CoordBase::xmin = -0.5 CoordBase::ymin = -0.5 CoordBase::zmin = -0.5 CoordBase::xmax = 0.5 CoordBase::ymax = 0.5 CoordBase::zmax = 0.5 CoordBase::ncells_x = 16 CoordBase::ncells_y = 16 CoordBase::ncells_z = 16 Carpet::max_refinement_levels = 3 CarpetRegrid2::num_centres = 1 CarpetRegrid2::active_1 = "yes" CarpetRegrid2::num_levels_1 = 1 CarpetRegrid2::radius_1[1] = 0.12 CarpetRegrid2::radius_1[2] = 0.04 }}} I was expecting then regridding to happen at iterations 4 and 8, however if you run the attached par file, a modification of balsara shocktube test, you see that the level additions actually happen at iterations 5 and 9 instead: {{{ ... INFO (CarpetRegrid2): Increasing number of levels of centre 1 to 2 (it=5) ... INFO (CarpetRegrid2): Increasing number of levels of centre 1 to 3 (it=9) }}} which is apparently an off-by-one kind of error. I tracked down the code producing these messages and it comes from function CarpetRegrid2_RegridMaps at CarpetRegrid2/src/regrid.cc, lines 745 to 747. In order for that piece of code to execute we do have to have do_recompose set to true. Strangely the condition to set it, compares the previous iteration to the regrid_every parameter on line 707 of the same file: {{{ (cctk_iteration - 1) % regrid_every == 0 }}} Investigating if this actually makes sense I was led to what I think it might be the source of the problem on line 58 of Carpet/src/Evolve.cc. Time and iteration is advanced before calling CallRegrid. Skimming over the AdvanceTime routine it is not clear to me that it really needs to be called before CallRegrid. If it is really needed then why the condition to regrid or not is not taken on the current updated iteration as in: {{{ cctk_iteration % regrid_every == 0 }}} Thanks, Bruno -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1906> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
