+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:
+ +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>= ;. + +
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).
+ + + +This release comprises the following tools, arrangements, and +thorns. Each tool/arrangement/thorn may have its own licencing +conditions, but all are available as open source:
+ +| Cactus | Flesh |
| CactusBase | Standard Cactus thorns |
| CactusConnect | |
| CactusElliptic | |
| CactusExternal | |
| CactusIO | |
| CactusNumerical | |
| CactusPUGH | |

| ExternalLibraries | Interfaces to external libraries |
| Carpet | Adaptive mesh refinement |
| EinsteinAnalysis | Einstein Toolkit |

| EinsteinEOS | |
| EinsteinEvolve | |

| McLachlan | BSSN implementation |
| TAT/TATelliptic | Various thorns |

| LSUThorns/QuasiLocalMeasures | |
| LSUThorns/SummationByParts | |
| Kranc | Automated code generation |
| GetComponents | Downloading tools and thorns |
| SimFactory | Building code and running simulations |
All repositories participating in this release carry a branch +ET_2010_06 marking this release. These release branches will +be updated if severe errors are found.
+ + + +This release has been tested on the following systems and +architectures:
+ +The Simulation +Factory contains ready-to-use configuration details for more than +20 additional systems, including most HPC systems +at LONI, +NERSC, +RZG, +and TeraGrid.
+ +The Einstein Toolkit thorns contain 89 regression test cases. +While all test cases pass on important systems, there are +unfortunately also some systems where certain test cases fail. We +verified that this is because of accumulation of floating-point +round-off error in most cases, and we will discuss this issue in a +broader context on the mailing list in the near future.
+ + + +The Einstein Toolkit web site contains online documentation for its +thorns, and pointers for using it to build your own code. There is +also a tutorial that explains how to download, build, and run the code +for a simple binary black hole evolution. We invite you to join our +mailing list +<users(a)einsteintoolkit.org&rt;.
