We are pleased to announce the eleventh release (code name +"Hilbert") of the +Einstein Toolkit, an open, community developed software infrastructure for +relativistic astrophysics. This release includes, among other things, +various improvements in the handling of external libraries (and with that, +installations), discontinue the direct support for Fortran 77 (use Fortran +90 instead), and enable the C++ code in GRHydro by default. +In addition, bug fixes accumulated since the previous release in November +2014 have been included.
+ +The Einstein Toolkit is a collection of software components and tools for +simulating and analyzing general relativistic astrophysical systems that bui= lds +on numerous software efforts in the numerical relativity community including +CactusEinstein, the Carpet AMR infrastructure and the relativistic +magneto-hydrodynamics code GRHydro. The Cactus Framework is used as the unde= rlying +computational infrastructure providing large-scale parallelization, general +computational components, and a model for collaborative, portable code +development. The toolkit includes modules to build complete codes for +simulating black hole spacetimes as well as systems governed by relativistic +magneto-hydrodynamics.
+ +The Einstein Toolkit uses a distributed software model and its different +modules are developed, distributed, and supported either by the core team of +Einstein Toolkit Maintainers, or by individual groups. Where modules are +provided by external groups, the Einstein Toolkit Maintainers provide quality +control for modules for inclusion in the toolkit and help coordinate support. +The Einstein Toolkit Maintainers currently involve postdocs and faculty from +six different institutions, and host weekly meetings that are open for anyone +to join in.
+ +Guiding principles for the design and implementation of the toolkit inclu= de: +open, community-driven software development; well thought out and stable +interfaces; separation of physics software from computational science +infrastructure; provision of complete working production code; training and +education for a new generation of researchers.
+ +For more information about using or contributing to the Einstein Toolkit,= or to +join the Einstein Toolkit Consortium, please visit our web pages at +<http://einsteintoolkit.org>= ;.
+ +The Einstein Toolkit is primarily supported by NSF +1212401/1212426/1212433/1212460 (Einstein Toolkit), and also by 0905046/0941= 653 +(PetaCactus) and 0710874 (LONI Grid).
+ +The Einstein Toolkit contains about 200 regression test cases. On a large +portion of the tested machines, almost all of these test suites pass, using = both +MPI and OpenMP parallelization.
+ +To upgrade from the previous release, use GetComponents with the new thor= nlist to check out the new version. Switching to the new branch is not possib= le for most repositories due to the repository move.
+ +See the Download pag= e on the Einstein Toolkit website for download instructions.
+ +Supported (tested) machines include:
+ +A * means that a small number of tests fail on that machine. Almost all t= ests pass on the other machines.
+All repositories participating in this release carry a branch ET_2015_05 +marking this release. These release branches will be updated if severe +errors are found.
