#582: Semi-automatically split McLachlan's calculations -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Split McLachlan's calculations semi-automatically in two ways: (a) by variable, so that e.g. dot[g] and dot[K] are calculated separately, and (b) by pattern, so that advection terms, dissipation, and "everything else" are calculated separately. Also introduce parameters to choose which routines are called at run time. This is somewhat a work in progress, in that the patch is good, but the API defined to split kernels is more complex and less failsafe than it should be. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/582> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1071: ensure atmosphere is properly set after ID

#1071: ensure atmosphere is properly set after ID -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2012_11 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- At the moment GRHydro doesn't ensure properly that the atmosphere is set after initial data. This is no problem as long as the ID thorn takes care of this, the ID doesn't contain atmosphere or the EOS is sufficiently robust to 'recover'. However, this is not always the case. Thus, I propose to set the atmosphere mask in PostInitial, initializing it according to whatever was setup there by some other thorn. The patch to do that is attached. It is only a change to schedule.ccl as the corresponding function already exists. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1071> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1152: Add option to compute center of mass to hydro_analysis and lots of smaller changes

#1152: Add option to compute center of mass to hydro_analysis and lots of smaller changes -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: Hydro_Analysis | -----------------------------------+---------------------------------------- The attached set of patches adds the possibility to compute a center of mass location to hydro_analysis. It works by computing the center of mass (via x[idx]*rho[idx]) of the matter in a region of radius Hydro_Analysis_r_core around the point of maximum density. Only points whose density is above a fraction Hydro_Analysis_rho_core_rel_min of the maximum density are considered. I also include a number of bugfix patches and patches to make Hydro_Analysis more controllable by user input rather than hard-coded values. All patches contain a short description in the patch (ie. the git commit message). The ones adding extra control and/or warnings are: * Hydro_Analysis: add verbosity_level option to control how much data to output to stdout * Hydro_Analysis: use Fortran modules for prototypes if available * Hydro_Analysis: add parameters to control which interpolator is used * Hydro_Analysis: make parameters steerable * Hydro_Analysis: warn if grid point with maximum value cannot be found on grid * Hydro_Analysis: add parameter Hydro_Analysis_comp_rho_max_every * Hydro_Analysis: add option rho_max_loc_use_rotatingsymmetry180 * Hydro_Analysis: add option to average the location of multiple identical maxima * Hydro_Analysis: fiddle with when to warn about multiple identical maxima Bugfixes are: * Hydro_Analysis: checkpoint grid scalars * Hydro_Analysis: do reduction in global mode New feature: * Hydro_Analysis: add routine to compute center of mass in core region -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1152> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1075: Test cases with specific number of processes -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- Some test cases require a specific number of processes. Instead not running, they should run on that number of processes. This would ensure that all tests execute all the time. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1075> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1388: New thorn MemSpeed -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- I have written a thorn MemSpeed, available at <https://svn.einsteintoolkit.org/incoming/MemSpeed>. This thorn is useful for performance tuning. I propose to add it to CactusUtils. From the README: Determine the speed of the CPU, as well as latencies and bandwidths of caches and main memory. These provides ideal, but real-world values against which the performance of other routines can be compared. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1388> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
