[Einstein Toolkit] #1729: Switch Carpet to new bboxset class implementation

#1729: Switch Carpet to new bboxset class implementation -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: eschnett Type: enhancement | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+-------------------------------------------------- Carpet has a new bboxset class implementation that scales to much larger number of MPI processes. I suggest to make the new implementation the default. This is currently disabled, and can be enabled by adding the two flags "-DCARPET_ENABLE_BBOXSET2 -DCARPET_USE_BBOXSET2" to CPPFLAGS. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1729> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1700: Use 64-bit integers when building PETSc

#1700: Use 64-bit integers when building PETSc -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- PETSc needs to be able to count up to the total (global) number of points it uses, not just process-local points. 32-bit integers are not sufficient for large runs. Note that e.g. Carpet already uses 64-bits integers for the same reason. I suggest to enable the respective option when building PETSc by default. TATPETSc supports this, other thorns may need to be updated. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1700> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1727: Support CCTK_INT16 -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- I suggest to add support for 16-byte integers to Cactus. I have created the respective patches and put them into "eschnett/int16" branches of the flesh and various arrangements, including CactusBase, CactusPUGH, and Carpet. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1727> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1694: try using fast fowards when accepting pull requests

#1694: try using fast fowards when accepting pull requests -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: optional | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- For small single change pull requests have a full git merge in the history can be annoying since it clutter the history view (it uses up two lines, it may show connecting both branches existing at the same time even if there are no commits on master during that time). We could try and instead find out if bitbucket can be made to allow fast forwards in the pull request merge (https://bitbucket.org/site/master/issue/6106/forced-non-fast-forward- merge-of-pull). Currently apparently bitbucket uses --no-ff ie it disallows fast forwards. We could even think about forcing fast forwards only (https://bitbucket.org/site/master/issue/9589/force-fast-forward-only- merges-on-pull). This does however not work so well for big "feature" branches that are brought back into master and where a fast forward may fail and/or require extensive rebasing of the feature branch. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1694> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1663: VisIT CarpetHDF5 plugin pseudocolor error

#1663: VisIT CarpetHDF5 plugin pseudocolor error ---------------------------------------+------------------------------------ Reporter: bruno.giacomazzo@… | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: visit | ---------------------------------------+------------------------------------ This problem has been present since the CarpetHDF5 plugin for VisIt became part of the standard VisIt distribution and it is still present in the current version of VisIt (2.8). When Pseudocolor is used in log scale and Centering is set to Original or Nodal, not all the values of the plotted quantity are shown (in particular lower values are not plotted at all). This does not happen if one sets Centering to Zonal, which instead shows the correct values. I have attached a couple of images showing the problem (they show hydrobase::rho for a BNS run). I do not know what may be causing it, but it may cause serious errors when analyzing data with VisIt (since one may miss some of the information on the low value regions). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1663> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1635: hwloc requires a certain minimum version, but does not check for it

#1635: hwloc requires a certain minimum version, but does not check for it --------------------+------------------------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2014_11 Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- Currently, hwloc's configuration.sh searched for any hwloc library and uses it. However, it requires a pretty new version within some of its own files, which leads to build failure on, e.g. Debian stable systems. The attached patch uses pkg-config to get the version of the installed hwloc library and if that version is older than 1.6 (educated guess, but see http://lists.einsteintoolkit.org/pipermail/users/2013-February/002860.html), builds the bundled version even if another version is installed (but too old). Note that this is done (intentionally) only if no library was specified, and the script was looking for it by itself. This allows users to specify something which will not be overwritten by this mechanism. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1635> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1702: AEILocalInterp and LocalInterp should output scheduled function name in error messages

#1702: AEILocalInterp and LocalInterp should output scheduled function name in error messages ----------------------------------------------------------------+----------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: AEILocalInterl LocalInterp CarpetInterp PUGHInterp | ----------------------------------------------------------------+----------- the local interpolation routines abort if an interpolation cannot be performed since the interpolation coordinates lie outside of the patch of data they are given eg. {{{ WARNING level 1 in thorn AEILocalInterp processor 0 (line 1109 of arrangements/AEIThorns/AEILocalInterp/src/Lagrange-tensor- product/../template.c): -> CCTK_InterpLocalUniform(): interpolation point is either outside the grid, or inside but too close to the grid boundary! (this may be caused by a global interpolation with driver::ghost_size too small) 0-origin interpolation point number pt=54181 of N_interp_points=54182 interpolation point (x,y,z)=(45.3992,15.5856,2.93915e-15) grid x_min(delta_x)x_max = -0.198(0.066)1.584 grid y_min(delta_y)y_max = -0.198(0.066)1.518 grid z_min(delta_z)z_max = -0.198(0.066)1.452 }}} However, if there are mutliple thorns that may call the interpolator it is no always clear which caller was active when the error occured (eg it may be the apparent horizon finder or the puncture tracker). It would be nice if the interpolators were to report the currently executing scheduled routine's name via CCTK_ScheduleQueryCurrentFunction. That routine currently takes cctkGH as an argument but does not actually use it. Thus, given the possible benefit, it would be acceptable I think to call the routine with a NULL pointer (and a comment that this is strictly not valid). An alternative, which may be nicer, would be to have the driver add an entry "cctkGH" to the table passed to {{{CCTK_InterpLocalUniform}}} in its {{{param_table_handle}}}. The local interpolator can then savely use this pointer if provided and (with an appropriate loud warning) fall back to passing NULL if it is not found (and stop the fallback once the flesh routine actually uses cctkGH). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1702> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1728: Remove CACHE_SIZE etc. from configure -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- Configure cannot reliably detect CACHE_SIZE since this may be different on build nodes and compute nodes. Thorn hwloc provides a reliable, portable run-time solution. CACHE_SIZE is not currently used either. I suggest to remove it from configure. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1728> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1724: Don't require configuration name in 'make CONFIG' if only one configuration is present

#1724: Don't require configuration name in 'make CONFIG' if only one configuration is present -------------------------+-------------------------------------------------- Reporter: knarf | Owner: knarf Type: enhancement | Status: new Priority: optional | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- For example 'make' after this pull request works if only one configuration is present. Otherwise a message would be output to tell the user to use 'make sim' (for example) - which is kind of pointless because at that point make "knew" already what was meant. It could, and should, just do it. https://bitbucket.org/cactuscode/cactus/pull-request/6/dont-require- configuration-name-when-only/diff -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1724> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
