For Debian this is a blocker since it prevents me from even downloading the code. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2069> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2064: Add GiRaFFE to the Einstein Toolkit

#2064: Add GiRaFFE to the Einstein Toolkit -------------------------------------------+-------------------------------- Reporter: zachetie@… | Owner: Type: enhancement | Status: new Priority: unset | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: GiRaFFE, GRFFE, IllinoisGRMHD | -------------------------------------------+-------------------------------- We (the authors of GiRaFFE) hereby request that GiRaFFE be added to the Einstein Toolkit. In short, GiRaFFE is the first open source, dynamical- spacetime code for modeling plasma flows in general relativistic force- free electrodynamics (GRFFE). It will be the best code in the Toolkit for modeling black hole and neutron star magnetospheres, as these magnetically-dominated regions are best modeled numerically by a GRFFE code (GRMHD codes break down when modeling very highly magnetized plasmas). Here is the commit ID for code reviewer comments: https://bitbucket.org/zach_etienne/wvuthorns/commits/ca2aab4ac66b404cddc6a3… Here is the original release announcement to the mailing list, including link to the code release paper: We are pleased to announce the public release of GiRaFFE, an open-source General Relativistic Force-Free Electrodynamics (GRFFE) code for dynamical spacetimes. -= Code Release Paper =- Our code release paper--including a full description of the GiRaFFE code, a discussion of potential applications of GiRaFFE, and code validation test results--has been uploaded to the arXiv: https://arxiv.org/abs/1704.00599 . -= Executive Summary =- GiRaFFE adopts the strategy pioneered by McKinney [1] and modified by Paschalidis and Shapiro [2] to convert a general relativistic magnetohydrodynamic (GRMHD) code into a GRFFE code. In short, GiRaFFE exists as an extensive modification to IllinoisGRMHD [3]. Both GiRaFFE and IllinoisGRMHD leverage the Einstein Toolkit’s highly-scalable infrastructure [4,5] to make possible large-scale simulations of magnetized plasmas in strong, dynamical spacetimes on adaptive-mesh refinement (AMR) grids. As you are aware, IllinoisGRMHD is an open-source rewrite of the Illinois Numerical Relativity Group's GRMHD code. GiRaFFE, on the other hand, is not based on any existing GRFFE code and is designed only to solve the equations of GRFFE in the context of fixed or dynamically-generated spacetimes. GiRaFFE has passed a large suite of GRFFE code validation tests passed by other state-of-the-art GRFFE codes, leading us to conclude that GiRaFFE is now ready for large-scale, state-of-the-art GRFFE simulations in dynamical spacetimes. -= New Thorns for the Einstein Toolkit =- All GiRaFFE thorns are listed below. Next to the name of each thorn, we include the number of lines of code to highlight the fact that GiRaFFE is quite compact and designed to be welcoming to new users. In addition, the comment-to-line-of-code ratio is very nearly 50%, and the code release paper provides a clean, broad-brush overview of the formalism and algorithms adopted. To become acquainted with any given thorn, first take a look at its README file. * GiRaFFE (~1,600 lines of code): Solves the GRFFE equations in the formalism of Paschalidis & Shapiro [2] using the same reconstruction (PPM) and staggered vector potential methods as IllinoisGRMHD. * GiRaFFEfood (~1,300 lines of code): Code validation initial data and basic diagnostics. Contains Five 1D tests in flat spacetime (fast wave, Alfvén wave, degenerate Alfvén wave, "three-wave", FFE breakdown), One 3D test in flat spacetime (aligned rotator), and Three 3D tests in curved spacetimes ("Exact Wald" solution, "Magnetospheric Wald" solution, and split monopole). * ShiftedKerrSchild (~230 lines of code): Sets up all 3+1 quantities for a Kerr-Schild spacetime with an arbitrary radial shift, to mitigate effects of extreme spacetime curvature near r_{KS}=0. See Appendix of code release paper for full discussion. * VolumeIntegrals_slab_Gfood (~310 lines of code): Performs volume integrals over arbitrary rectangular prisms as specified in parameter files. * GiRaFFE_to_HydroBase & ID_converter_GiRaFFE (~230 lines of code): Acts as a translation layer to convert 3-velocities in HydroBase's Valencia formalism to/from the 3-velocity found in the induction equation (v^i = u^i/u^0; native to GiRaFFE). -= License =- To maximize compatibility with existing thorns in ET, all of the aforementioned GiRaFFE thorns are either licensed GPLv2+ or 2-clause BSD (FreeBSD). See LICENSE file in each. -= Download GiRaFFE! =- The collection of thorns comprising GiRaFFE may be downloaded here: https://bitbucket.org/zach_etienne/wvuthorns Sincerely, The GiRaFFE team -Zach Etienne -Mew-Bing Wan -Maria Babiuc -Sean McWilliams -Ashok Choudhary References: [1] J.C.

This will make relative errros smaller and will be particularly noticeable in cases where the last dataset was small or zero.

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

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
