\begin{abstract} -We describe the Einstein Toolkit, a community-driven, freely accessible -computational infrastructure intended for use in numerical relativity, -relativistic astrophysics, and other applications. The Toolkit, developed by a -collaboration involving researchers from several institutions in the United -States and others around the world, combines all of the components needed to -simulate astrophysical objects including black holes, compact objects, and -collapsing stars, as well as a full suite of analysis tools. It is based on -commonly used packages, such as the Cactus Framework for HPC computing and the -Carpet adaptive mesh refinement driver, but is under continuous development and -contains many new code components that have been publicly released for the -first time. We discuss the motivation behind the release of the toolkit, the -philosophy underlying its development, and the goals of the project. A brief -summary of numerical techniques is included, as are results of numerical test -covering a variety of sample astrophysical problems. We conclude with a -discussion of future directions in which the toolkit is likely to be expanded. +We describe the Einstein Toolkit, a community-driven, freely +accessible computational infrastructure intended for use in numerical +relativity, relativistic astrophysics, and other applications. The +Toolkit, developed by a collaboration involving researchers from +several institutions around the world, combines a core set of +components needed to simulate astrophysical objects including black +holes, compact objects, and collapsing stars, as well as a full suite +of analysis tools. The Einstein Toolkit is based on the Cactus +Framework for high-performance computing and the Carpet adaptive mesh +refinement driver. It implements spacetime evolution via the BSSN +evolution system and general-relativistic hydrodynamics in a +finite-volume discretization. The toolkit is under continuous +development and contains many new code components that have been +publicly released for the first time and are described in this +article. We discuss the motivation behind the release of the toolkit, +the philosophy underlying its development, and the goals of the +project. A summary of the implemented numerical techniques is +included, as are results of numerical test covering a variety of +sample astrophysical problems. \end{abstract}
