The Einstein Toolkit is +a collection of over 130 software components and tools for simulating +and analyzing general relativistic astrophysical systems that builds +on numerous software efforts in the numerical relativity community +including CactusEinstein, the Whisky hydrodynamics code, and the +Carpet AMR infrastructure. The Cactus Framework is used as the +underlying 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 hydrodynamics. Current +development in the consortium is targeted at providing additional +infrastructure for general relativistic magnetohydrodynamics.</p> + +<p>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 five different +institutions, and hold weekly meetings that are open for anyone to +join in.</p> + +<p>Guiding principles for the design and implementation of the toolkit +include:</p> + +<nl> +<li>Open, community-driven software development that encourages the +sharing of code across the community, prevents code duplication, and +leads to sustainable support and development of essential code.</li> + +<li>Well thought out and stable interfaces between components that +enable multiple implementations of physics capabilities, and allow +groups or individuals to concentrate on their areas of interest.</li> + +<li>Separation of physics software from computational science +infrastructure so that new technologies for large scale computing, +processor accelerators, or parallel I/O can be easily integrated with +science codes.</li> + +<li>The provision of complete working production codes to provide: +prototypes, standard benchmarks, and testcases; codes that are +available for and usable by the general astrophysics community; tools +for new researchers and groups to enter this field; training and +education for a new generation of researchers.</li> +</nl> + +<p>For more information about using or contributing to the Einstein +Toolkit, or to join the Einstein Toolkit Consortium, please visit our +web pages at +<<a href="http://einsteintoolkit.org">http://einsteintoolkit.org</a>>. + +<p>We thank the numerous people +who <a href="../../credits">contributed</a> to this software over the +past many years; there are too many to be listed here. We also +gratefully acknowledge those who helped in the past months to make +this release happen.
