| − | We are pleased to announce the first release (code name "Bohr") of the
| |
| − | Einstein Toolkit, an open, community developed software infrastructure
| |
| − | for relativistic astrophysics. 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.
| |
| − | | |
| − | 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.
| |
| − | | |
| − | Guiding principles for the design and implementation of the toolkit
| |
| − | include:
| |
| − | | |
| − | 1: 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.
| |
| − | | |
| − | 2: 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.
| |
| − | | |
| − | 3: 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.
| |
| − | | |
| − | 4: 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.

| − | For more information about using or contributing to the Einstein
| |
| − | Toolkit, or to join the Einstein Toolkit Consortium, please visit our
| |

| |
| − | | |
| − | We thank the numerous people who contributed 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. The Einstein Toolkit is primarily supported by
| |
| − | NSF 0903973/0903782/0904015 (CIGR), and also by NSF 0701566/0855892
| |
| − | (XiRel), 0721915 (Alpaca), and 0905046/0941653 (PetaCactus).
