#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] #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

[Einstein Toolkit] #1599: CarpetInterp/waveinterp_2p tests constant in time initial data

#1599: CarpetInterp/waveinterp_2p tests constant in time initial data --------------------------+------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: CarpetInterp | --------------------------+------------------------------------------------- the test waveinterp_2p sets up initial data using IDWaveMoL (fom CactusExamples) using kx=ky=kz = 0. and slopet = 0.1. Ie the initial data is constant in space and has frequency 0.1. It then evolves this using WaveMoL and interpolates in space and time with CarpetInterp. Since the function is constant in space (exactly so, see eg the output in InterpToArray::array1d_vars[0]) the interpolation in space just tests roundoff errors. The second time derivative (array1d_vars[2]) should be zero and all we measure in the test is truncation errors on the level of 1e-9. This makes the test very sensitive to -Ofast, -O0, gcc vs. intel etc. and not a very good test. I would rather either use a Gausian wave for initial data so that there is some actual data in the result and not just numerical noise, or leave out the 2nd time derivative from the test data. The test fails due to significant errors in a virtual machine using ubuntu.cfg (which usies -ffast-math and -O2). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1599> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2022: thorn guide on et website links to pdf pages -------------------------------------+-------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- This is a continuation #2010 which was about the thorn guide being missing. This one is about the link behind "Thorn Guide" on http://einsteintoolkit.org/documentation.html, namely http://einsteintoolkit.org/thornguide/ points to an auto-generated index page of a directory of pdf files. Instead of the correct HTML page for a table of content pointing to html pages of documentation. Likely requires web server access to fix. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2022> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2030: Multi-block boundaries leave uninitialized boundary points

#2030: Multi-block boundaries leave uninitialized boundary points -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- Applying multi-block boundaries can leave uninitialized boundary points. This happens when multi-block boundaries are used in combination with another boundary condition that looks at the interior of the grid, such as e.g. a symmetry condition or radiative / extrapolating boundaries. There is another bug currently in McLachlan that applies its "scalar" boundary conditions to too few grid points (it uses "BoundaryNoSync" instead of "Boundary"), which means there are uninitialized boundary points for {{{initial_boundary_condition = "scalar"}}} as well in multi- block systems. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2030> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
