The Einstein Toolkit by Erik Schnetter
From Carpet Workshop
Title: The Einstein Toolkit
Abstract: We introduce the Einstein Toolkit, a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems. Such systems include gravitational wave space-times, collisions of compact objects such as black holes or neutron stars, accretion onto compact objects, core collapse supernovae and Gamma-Ray Bursts. This toolkit is developed as open software for relativistic astrophysics. Our aim is to provide the core computational tools that can enable new science, broaden our community, facilitate interdisciplinary research and take advantage of emerging petascale computers and advanced cyberinfrastructure. We believe that this toolkit can also be constructively used in teaching numerical relativity courses, and can help "getting started" in numerical relativity research. The Einstein Toolkit builds on numerous software efforts in the numerical relativity community including CactusEinstein, Whisky, and Carpet. The Einstein Toolkit currently uses the Cactus Framework as the underlying computational infrastructure that provides large-scale parallelization, general computational components, and a model for collaborative, portable code development. We give a brief overview over the toolkit, its goals, and its current state, and show examples of scientific results obtained by various research groups employing this toolkit as basis of their research codes.
