[Einstein Toolkit] #1769: External libraries: moving towards multiarch library directory structure

#1769: External libraries: moving towards multiarch library directory structure ----------------------------------------------+----------------------------- Reporter: bmundim | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2015_05 Component: EinsteinToolkit thorn | Version: development version Keywords: ExternalLibraries HDF5 Multiarch | ----------------------------------------------+----------------------------- Several Linux distributions have already started to move their libraries to a new directory structure that reflects the target architecture and allows the installation of packages from multiple architectures in the same system. The following links provide more details of this change: {{{ https://wiki.debian.org/Multiarch/TheCaseForMultiarch https://wiki.ubuntu.com/MultiarchSpec }}} This change potentially affects several of external library scripts shipped with ET. For example the HDF5/src/detect.sh script is not able to detect the hdf5 libraries installed in the directory /usr/lib/x86_64 -linux-gnu for Ubuntu 14.04.2 LTS. I have attached a simple patch to remedy this issue and open a discussion on the best way to proceed here. This patch does depend on the availability of gcc on the system. It currently works fine for me, but we might need a better solution for systems without gcc. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1769> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1474: compile ExternalLibraries with other thorns rather than when CST runs

#1474: compile ExternalLibraries with other thorns rather than when CST runs -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- Compiling external libraries takes a long time by now. Currently this happens very early in the compilation phase, before the other thorns are compiled. It would be better if the compilation happened at the same time as that of other thorns. This will entail splitting the configuration ie. detecting whether to build the included source or use a system wide copy from the compilation, most likely either using Cactus makefile variables or temporary files to transfer the decisions from the configuration stage to the build stage. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1474> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1946: sim setup should create a section for the current machine

#1946: sim setup should create a section for the current machine -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: SimFactory | Version: development version Keywords: | -------------------------+-------------------------------------------------- When calling sim setup on a machine in the machine data base (eg bluewaters in my case) it it still creates only a {{{[default]}}} section in defs.local.ini which means that the account information and possibly non-default sourcebasedir are not used for bluewaters leading to hard to understand error messages later on. I would thus like to suggest to change sim setup such that instead (or in addition to) a "[default]" section it creates a section for the detected machine if it already knows this machine. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1946> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1995: McLachlan constraint tests fail

#1995: McLachlan constraint tests fail ---------------------------------------------------------------+------------ Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2016_11 Component: EinsteinToolkit thorn | Version: development version Keywords: McLachlan constraints tests compiler optimization | ---------------------------------------------------------------+------------ Several tests fail on several machines, and the cause seems to be the constraints calculated by McLachlan. Peter is looking into this. We see test failures in the thorns Dissipation and RotatingSymmetry90/180. Indications are that most failures happen with Intel 15, but some are apparently also seen with Intel 16, while others with Intel 16 seem to work fine. Optimization -O1 instead of -O2 seems to prevent the problem, but is not a viable workaround. A simple 'print' statement in the affected (auto-generated) code also makes the problem disappear. Running using one MPI process and one openMP thread reproduces the problem. valgrind does not find anything obvious pointing to memory mess-up. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1995> 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

It only affects the file bbox.cc. Happened on two different clusters.

#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
