[Einstein Toolkit] #1308: MPI: use library list provided by mpic++ instead of guessing (wrong)

#1308: MPI: use library list provided by mpic++ instead of guessing (wrong) -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2013_05 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- At the moment, ExternalLibraries/MPI guesses that the library list for openmpi is just 'mpi mpi_cxx'. This is wrong in my case (even for the built library; I need additional libraries. The OpenMPI FAQ mentions this: "NOTE: It is absolutely not sufficient to simply add "-lmpi" to your link line and assume that you will obtain a valid Open MPI executable." They do recommend to use the compiler wrappers. I didn't try that, leaving a patch to a minimum. I would also not be sure how to replace to actual compilers using a thorn while it is supposedly being compiled - after the Cactus configure state (cannot do it before since the wrappers might not be build yet). Thus, I go the second way - also shown in the FAQ: I use mpic++ to get hold of the flags that are needed when linking against the library. This is very similar to what happens for some of the other ExternalLibraries as well (but a bit simpler since they also provide options to just get a list of the libraries, not including the flags themselves - which is what Cactus expects). In my case, this uses the libraries 'mpi_cxx mpi nsl util m m nsl util m dl openmp'. Especially the missing 'util' in the current list prevented me from linking. Adding it hard to the list however might be wrong on systems where this is not needed or that library might not even exist. (and this isn't the only missing library) I would like this to be included in the next release, as this would otherwise prevent people from building on at least some of the major Linux distros out of the box (Debian wheezy here) - or we would have to specify the library list by hand for these systems. Given the central part MPI plays I set this to 'major'. If we see problems with this approach we can still guess the missing libraries and try that, until after the release.

[Einstein Toolkit] #1305: Building Einstein Toolkit requires using 'Build' twice

#1305: Building Einstein Toolkit requires using 'Build' twice ----------------------------------------+----------------------------------- Reporter: srichers@… | Owner: sbrandt Type: defect | Status: new Priority: minor | Milestone: Component: Mojave | Version: Keywords: | ----------------------------------------+----------------------------------- When building a config in EinsteinToolkit for the first time the following errors come up: find: `configs/Cfg1/ThornList': No such file or directory find: `configs/Cfg1/config-data': No such file or directory find: `configs/Cfg1/config-info': No such file or directory Checking the folder in .mojaveconfig/projectname after the build reveals the files are present. Running build a second time completes successfully. This does not happen when running simfactory directly, nor does it happen when using Mojave to build the WaveToy demo. (note, optionfile allows building using 32 processes...just a timing issue?) -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1305> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1301: Formaline should store the thornlist -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- Formaline should store the thornlist used to build the configuration. This will make it easier to reconstruct a working Cactus tree from the Formaline output. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1301> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1300: GRHydro: riemann_solver should be steerable.

#1300: GRHydro: riemann_solver should be steerable. -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: ET_2013_05 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- Although probably often not wanted, there is no reason to have riemann_solver not steerable=always. In fact, I recently wanted to do just this: change the riemann solver mid-simulation (through the Trigger thorn in that case) and had to change the source and recompile for this. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1300> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

We have a number of changes to Roland's variant of Scott's original Bondi solution (in BondiM.c) and tests for the entropy con2prim. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1296> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1295: GRhydro updates -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: GHydro | -----------------------------------+---------------------------------------- usual deal. Will apply on Wednesday unless objections are raised. This bunch has an improvement to the HLLE solver (by Christian Reisswig) and a method to solve con2prim using entropy instead of tau (by Bruno Mundim). The other patches are minor formating issues and a bugfix for hot oes runs using MHD. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1295> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1298: Run part of CST before external libraries -------------------------+-------------------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- Part of CST should run already before external libraries are built. In particular missing thorns (in the thornlist, but not present in the checkout) should produce an error message as early as possible. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1298> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1292: problem with complex ASCII output

#1292: problem with complex ASCII output -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Christian Reisswig reports: there seems to be a problem with complex ASCII output. Instead of outputting real and imaginary part into two separate columns, it now combines it into one column plus there are brackets, e.g. one complex number is output as "(3.14,0.2)" instead of "3.14 0.2". -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1292> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
