[Einstein Toolkit] #2181: update OpenMPI tarball to 1.10.7

#2181: update OpenMPI tarball to 1.10.7 ---------------------------------+----------------------------------- Reporter: Roland Haas | Type: defect Status: new | Priority: major Milestone: | Component: EinsteinToolkit thorn Version: development version | Keywords: MPI ---------------------------------+----------------------------------- Compiling on bethe (a private workstation at Caltech that is however part of http://einsteintoolkit.org/testsuite_results/index.php) fails due to the OpenMP source code not (anymore) being compatible with ibverbs library installed on the system (leaving aside the question why a single workstation would have infiniband libraries installed in the first place). Updating to 1.10.7 fixes this. Attached please find a patch (sans tarball which can be downloaded from here https://www.open-mpi.org/software/). Using these changes lets me compile MPI successfully and eventually builds the ET as well. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2181> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2188: running on wheeler fails with error messages from MPI

#2188: running on wheeler fails with error messages from MPI -------------------------+--------------------------------- Reporter: Roland Haas | Owner: Erik Schnetter Type: defect | Status: assigned Priority: major | Milestone: ET_2018_08 Component: SimFactory | Version: development version Keywords: | -------------------------+--------------------------------- Trying to run on wheeler fails with lengthy error messages from MPI even when using a single MPI rank. I attach a sample error file from the gaussian test in the testsuite. Wheeler is a private machine at Caltech so if this cannot be fixed I would remove it from the list of machines shown on http://einsteintoolkit.org/testsuite_results/index.php . Erik since you maintained wheeler's files and the machine files point to an MPI stack in your $HOME, do you want to look into this? Otherwise I can set up a machine setup using the software stack used by SpEC (which sees much more regular use on wheeler) but that will likely not use the same set of modern compilers and other software that your setup uses, or we can remove wheeler from the list of officially supported machines for this release. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2188> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1889: correct finding normalization value for relerr compuation

#1889: correct finding normalization value for relerr compuation --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- Before it would have taken the larger of the abs value of the new and old data of the last data set rather than the largest abs value of the new and old data of all the datasets. This will make relative errros smaller and will be particularly noticeable in cases where the last dataset was small or zero. This should get rid of the "Error, how did I get here" warnings (that really indicated an logic error). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1889> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2055: Move gallery examples to EinsteinExamples repository

#2055: Move gallery examples to EinsteinExamples repository -------------------------------------+-------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- The [http://einsteintoolkit.org/gallery.html Einstein Toolkit Gallery examples] parameter files could be moved from the [https://bitbucket.org/einsteintoolkit/www/src/master/gallery/?at=master www] repository to the [https://bitbucket.org/einsteintoolkit/einsteinexamples/src/master/par/?at=m… EinsteinExamples] repository and arrangement. This would mean: * They are checked out when someone downloads the ET, avoiding a separate web browser or curl download * They will have branches like the rest of the ET, so they can be associated with a given release if necessary Note that this will separate them from the other related material on the website, such as thornlists, images, etc, but I think it is worth it to make it easier for new users. Eventually, we hope that all the gallery examples will use the standard ET thornlist anyway. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2055> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2042: new thorns for hydro analysis
by Einstein Toolkit 28 Aug '18

#2042: new thorns for hydro analysis -------------------------+-------------------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: Other | Version: development version Keywords: | -------------------------+-------------------------------------------------- The LSU and Parma groups developed, and used for publications, a set of two thorns for analysis of hydro quantities, in particular for mode analysis. We would like to have those included in the Einstein Toolkit. We are aware that a few things are still missing for that (documentation, test suites), but before we go that extra step and create all of that, we want to be sure the following is seen as 'ok': The main thorn (GRHydro_Analysis, _not_ to be specific to GRHydro, it only inherits hydrobase - could and should probably be renames) does reductions of quire a few quantities. In practice, the memory required for this turned out to be a problem on some machines. These reductions are done at ANALYSIS, which means even telling Cactus to allocate/deallocate not once, globally, but instead doing that every time step does not help. Thus, there is a second thorn, a utility thorn called 'TempPool'. It's task is nothing else than to provide an array of grid functions that are always allocated, but which can be used by other thorns for, reductions - and, and this is the interesting part - can be re-used by other thorns, for other reductions after that; within the same time step in ANALYSIS. This is how TempPool is used by GRHydro_Analysis. TempPool is not tied to GRHydro_Analysis. Any other thorn can also request storage there, but there currently isn't another thorn. It just seemed to good idea to split this functionality. The book keeping already now makes sure that the number of allocated grid functions is only as large the maximum of any thorn using it. The relevant code can be found here: https://bitbucket.org/GravityPR/prthorns/src I'd like another developer to have a look and give input. Once/If this is deemed ok to be included, we will add the necessary documentation and test suites and make a proper proposal for inclusion. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2042> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2189: Carpet/CarpetLib: Add Lagrange_third_order_prolong prolongation option.

#2189: Carpet/CarpetLib: Add Lagrange_third_order_prolong prolongation option. -------------------------+--------------------------------- Reporter: zachetie@… | Owner: rhaas@… Type: enhancement | Status: assigned Priority: unset | Milestone: Component: Other | Version: development version Keywords: | -------------------------+--------------------------------- When the default prolongation type is chosen in a dynamical spacetime evolution, hydrodynamic and GRMHD fields can suffer from spurious oscillations generated at AMR refinement boundaries due to the high-order Lagrange polynomial prolongation. As there is no way to directly specify the prolongation order in the interface.ccl, I have created a Carpet pull request that adds the desired order (3rd) Lagrange polynomial prolongation: https://bitbucket.org/eschnett/carpet/pull-requests/21/ I would like this to be the default prolongation option for IllinoisGRMHD and GiRaFFE, so it would be immediately useful. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2189> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
