#2080: Backports for the June 2017 release to compile on the NDS machine -------------------------+-------------------------------------------------- Reporter: sbrandt | Owner: Type: enhancement | Status: new Priority: critical | Milestone: Component: Other | Version: development version Keywords: | -------------------------+-------------------------------------------------- I would like to backport the following files from master to the June 6th release of the ET. The files are repos/simfactory2: bin/sim mdb/machines/jupyteret.ini mdb/optionlists/generic.cfg mdb/runscripts/generic.run Also, a small modification to the PAPI thorn: {{{ Index: src/detect.sh =================================================================== --- src/detect.sh (revision 42) +++ src/detect.sh (working copy) @@ -27,7 +27,7 @@ # libraries might have different file extensions for libext in a dll dll.a dylib lib so; do # libraries can be in lib or lib64 (or libx32?) - for libdir in lib64 lib; do + for libdir in lib64 lib lib/x86_64-linux-gnu; do # These files must exist FILES="include/papi.h ${libdir}/libpapi.${libext}" # assume this is the one and check all needed files }}} With these changes, the ET builds on the NDS machine. Moreover, it should more easily build on machines which have no explicit entry in Simfactory. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2080> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2029: GW150914 example should be updated to work with the Einstein Toolkit thornlist

#2029: GW150914 example should be updated to work with the Einstein Toolkit thornlist -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Other | Version: development version Keywords: gallery | -------------------------+-------------------------------------------------- The GW150914 example currently uses its own thornlist, because Llama was not part of the ET when it was created. Llama has now been added to the ET. The GW150914 thornlist uses WaveExtractCPM and ADMConstraints. These can probably be removed, for the sake of having a parameter file which works with the ET thornlist. ADMConstraints can be replaced with ML_ADMConstraints. WaveExtractCPM is an "in-development" code which has not been extensively tested. It gives the GW strain directly from Schwarzschild perturbation theory, without needing to go via fixed- frequency integration of Psi4, so is good for quick plots. However, it seems to give worse results than Psi4 for the ringdown, and possibly has bugs in some of the l > 2 modes, so I don't think it is ready for inclusion in the toolkit just yet. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2029> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1725: Disable Fortran 77 support in Cactus

#1725: Disable Fortran 77 support in Cactus -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: unset | Milestone: Component: Other | Version: development version Keywords: | -------------------------+-------------------------------------------------- There are no "Fortran 77" compilers any more. Cactus currently distinguishes between FCODE and F90CODE (pure Fortran 77, and Fortran 90). The pure Fortran 77 code has less argument checking etc. and is less safe, and is not needed any more. It should be removed, both from the makefile system as well as from the CST that auto-generates code. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1725> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2100: Host a collection of numerical relativity talk slides -------------------------------------+-------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- There seems to be no good place to find the slides for scientific talks that people have given, e.g. something like an arxiv for talks. In the absence of this, we could have a page on the ET website which collects together slides from talks on numerical relativity. We could either host the PDF slides themselves, or we could point to externally-hosted slides. Thoughts? -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2100> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2021: compiling Carpet fails with intel 17 and optimisation -----------------------------------------+---------------------------------- Reporter: wolfgang.kastaun@… | Owner: eschnett Type: defect | Status: new Priority: unset | Milestone: Component: Carpet | Version: Keywords: | -----------------------------------------+---------------------------------- Compiling carpet with intel 17.0.1 and -O2 or -O3 triggers an internal compiler error ("internal error: 0_76"). It only affects the file bbox.cc. Happened on two different clusters. ET version is Payne. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2021> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2072: Carpet: Disable OpenMP parallelization of transport operators

#2072: Carpet: Disable OpenMP parallelization of transport operators -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: eschnett Type: enhancement | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+-------------------------------------------------- This disables the OpenMP parallelization of Carpet's transport operators. I have observed that this leads to a significant speedup when many threads are used. The likely reason is that the regions which are parallelized are typically small. A typical reason would e.g. be the lower x-boundary of one component of one grid variable. The OpenMP thread startup overhead and the cache misses caused by parallelizing this are then larger than any benefit. See <https://bitbucket.org/eschnett/carpet/pull-requests/18/carpet- disable-openmp-parallelization-of/diff>. In a next step (not proposed here), we can parallelize transport operators again, but at a much higher level, e.g. at the level of the loop over all variables that need to be prolongated. However, Carpet currently (and quite unfortunately) uses static variables to hold pointers to timers, and these are not thread-safe. (Neither the static variables nor the timer implementation itself are.) This needs to be either corrected or disabled, which will be the topic of a further pull request. At this time, I ask some of those who are interested in performance in trying this pull request on a few iterations of a production simulation that uses many OpenMP threads and report back here. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2072> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1784: osx-homebrew.cfg does not work out of the box on Yosemite

#1784: osx-homebrew.cfg does not work out of the box on Yosemite ------------------------+--------------------------------------------------- Reporter: anonymous | Owner: Type: task | Status: new Priority: optional | Milestone: Component: SimFactory | Version: ET_2015_05 Keywords: | ------------------------+--------------------------------------------------- When installing ET anew on Yosemite with the instructions in osx-homebrew.cfg, the build fails because homebrew gets the latest version of gcc (5.1), which is currently not the one then specified in the cactus compilation options (4.9). This problem was encountered by a student who approached ET for the first time. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1784> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1757: Stampede needs to be updated

#1757: Stampede needs to be updated ----------------------+----------------------------------------------------- Reporter: hinder | Owner: Type: task | Status: new Priority: critical | Milestone: Component: Other | Version: development version Keywords: backport | ----------------------+----------------------------------------------------- The SimFactory definition for Stampede currently uses the intel/13.1.1.163 compiler. This compiler will be removed next Tuesday (see https://portal.tacc.utexas.edu/user-guides/stampede/intel15). According to TACC, the current default is the older intel/13.0.2.146, and this is the recommended and default compiler, and will remain so. Both compilers have the "restrict" keyword blacklisted in Cactus (#1276). They will install intel/15.0.1 at the end of April. There is also intel/14.0.1.106 available, but it is labeled as "limited software stack". It is not clear why they are removing a newer compiler, or why they chose to do this a month before installing an even newer one. Our options are: 1. Upgrade to intel/14.0.1.106, which is labeled as "limited software stack" 2. Downgrade to intel/13.0.2.146, which is the default and will remain so for a while This should be done both for the trunk and the release branch. I suggest that option 2 is the most conservative, and probably the easiest, as there might be libraries which are not compiled for intel/14.0.1.106. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1757> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
