[Einstein Toolkit] #2203: accumulated Carpet updates

#2203: accumulated Carpet updates -------------------------+--------------------------------- Reporter: Roland Haas | Owner: Roland Haas Type: defect | Status: assigned Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+--------------------------------- Pull requests https://bitbucket.org/eschnett/carpet/pull-requests/22 /rhaas-carpetupdates/diff https://bitbucket.org/cactuscode/cactus/pull- requests/53/rhaas-updates/diff https://bitbucket.org/cactuscode/cactuspugh /pull-requests/3/pugh-initialize-new-cgh-fields/diff contain accumulated updates to Carpet, Cactus and PUGH in the funhpc branches. I have verified that the three pull requests produce bit-identical output for the qc0-mclachlan.par parfile using 5 MPI ranks and 2 threads per rank on my workstation (debian-buster, gcc 8.2). A summary of changes: * add support for very large grids where 64bit integer are needed for grid indices and sizes of transfer buffers * fix how how physical_time_per_hour is computed * add functionality to align interior of grid functions to cache boundaries. This requires changes to Cactus and PUGH as well. * add a parameter "granularity" to make sure the interior of components is a multiple of N points in each direction * always align data if VECTORISE_ALIGN_FOR_CACHE is set in option list indep. of pad_to_cachelines runtime parameter * cleanup, reformatting, minor speedups To compare the changes it is not advisable to look at the diff directly. It is much better to run both the current and the new version through clang-format first: {{{ cd repos/carpet git checkout master git checkout -b master-formatted clang-format -style=file -i */src/*.{cc,hh} git commit -a -m 'Beautify code' git checkout rhaas/carpetUpdates git checkout -b rhaas/carpetUpdates-formatted clang-format -style=file -i */src/*.{cc,hh} git commit -a -m 'Beautify code' git diff master-formatted..rhaas/carpetUpdates-formatted }}} which is more manageable (but still multiple thousands of lines) -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2203> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2206: make LORENE2 the default LORENE in the ET

#2206: make LORENE2 the default LORENE in the ET ---------------------------------+----------------------------------- Reporter: Roland Haas | Type: enhancement Status: new | Priority: minor Milestone: | Component: EinsteinToolkit thorn Version: development version | Keywords: ---------------------------------+----------------------------------- We are currently shipping two versions of LORENE with the ET: * ExternalLibraries/LORENE * ExternalLibraries/LORENE2 which are different snapshots of LORENE which produce / read incompatible binary blobs as data files for the produced initial data. See ticket:1817#comment:28 . Frank used to spearhead this effort (with me arguing for a new name to keep backwards compatibility). By now LORENE2 should be made the default code used and LORENE the one downloaded but not compiled in (they cannot both be compiled due to linker conflicts). This has become a bit more urgent since Debian (and hence Ubuntu soon) are including LORENE in the version from cvs20161116 in their stable release (stretch): https://packages.debian.org/stretch/liblorene-dev CVS being what it is (and us not knowing which commit caused the change in binary format in the first place) it is not clear whether this is what the ET calls LORENE or LORENE2, but my guess would be it is LORENE2. Ideally there would be a one release warning before this happens, unfortunately the release announcement mentioning LORENE2 does not do so: https://www.einsteintoolkit.org/about/releases/ET_2017_06_announcement.html Having a LORENE copy present would speed up compilation a bit and is already being proposed on the wiki: https://docs.einsteintoolkit.org/et- docs/Simplified_Tutorial_for_New_Users#Speed_up_installation_by_using_native_packages -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2206> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

This happens even if one passes the {{{--with-cuda=no}}} option to OpenMPI's configure script.

#2151: thorn NSTracker cannot track unequal mass neutron star systems ---------------------------------+------------------------- Reporter: Roland Haas | Type: enhancement Status: new | Priority: optional Milestone: | Component: Other Version: development version | Keywords: NSTracker ---------------------------------+------------------------- NSTracker makes the hard-coded assumption that if there are two NS then one is at (x,y,z) and the other one at (-x,-y,z). It (and the code in Hydro_Analysis) should support an arbitrary number of NS with arbitrary symmetries imposed. Note that NSTracker is not part of the ET but used by one of the gallery examples. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2151> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
