[Einstein Toolkit] #1266: Featue request for Parity Symmetry thorn

#1266: Featue request for Parity Symmetry thorn ---------------------------------+------------------------------------------ Reporter: yosef@… | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Other | Version: Keywords: | ---------------------------------+------------------------------------------ I started looking at runs with parity symmetry, that is the only symmetry is the simultaneous reflection about x, y, and z. I think I was able to "implement" this symmetry by changing just a handful of lines in Rotating180 and I'm a little less sure about my changes to carpetregrid2. I was wondering, would there be any interest in adding this symmetry to ET? -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1266> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1384: simplify using Refluxing with MoL

#1384: simplify using Refluxing with MoL -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Other | Version: development version Keywords: Refluxing | -------------------------+-------------------------------------------------- currently one needs to set two parameters when using Refluxing with GRHydro only: nvars and nvars_evolved which are set to the same value. The two different parameters allow refluxing to be used with thorns that implement their own timestepping indedpendent of MoL. To simplify usage in situations where only MoL is used I proposed to introduce a new parameter nvars_not_evolved_with_MoL which defaults to zero and to retire nvars_evolved in favor of the new parameter. This would make MoL based simulations with only a single parameter choice possible. Alternatively we could have a second string non_MoL_refluxing_variables that lists the variables which have refluxing applied to them but are not evolved with MoL. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1384> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1476: Use mvapich2 instead of impi on Stampede ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2013_11 Component: Other | Version: development version Keywords: | ----------------------+----------------------------------------------------- mvapich2 is the default, has probably less problems, and should provide a higher performance. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1476> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1485: Remove support of StaticConformal from ADMMacros

#1485: Remove support of StaticConformal from ADMMacros -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: ET_2014_05 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- The attached patch removes support of StaticConformal from ADMMacros. The patch tries to do this in a minimal way, e.g. it set's the macros to 0. or 1. Optimizing this isn't worth it IMHO, we should instead look into a replacement of the thorn itself in the long run. However, in the meantime, this patch enables us to remove the dependency on StaticConformal from thorns using ADMMacros. This lets testcases fail that actually use a static conformal metric (from ADM, ADMConstraints, Extract, and IDAnalyticBH) - which is expected. All others succeed. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1485> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1486: GRHydro updates

#1486: GRHydro updates -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: GRHydro | -----------------------------------+---------------------------------------- two updates that I had already prepared for inclusion quite a while ago. To be included after the release. 0001 improves handling of mangnetic fields inside of the excised region by being less aggressive when resetting to atmosphere values. 0002 ensures that the trivial_rp grid function has the same memory layout at the other grid functions. Given that way that reconstruction is done, there was nothing actually wrong with the previous method though (even when padding is used so that cctk_ash != cctk_lsh). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1486> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

It required a patch to the flesh to detect the shared memory support functions in the OS. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/995> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
