+
+<p>
+We are pleased to announce the first release (code name
+"<a href=3D"http://en.wikipedia.org/wiki/Bohr-Einstein_debates">Bohr</a>")
+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.</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

+
+<p>We thank the numerous people
+who <a href=3D"../../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.  The Einstein Toolkit is primarily supported by
+NSF 0903973/0903782/0904015 (CIGR), and also by NSF 0701566/0855892
+(<a href=3D"http://www.cct.lsu.edu/xirel/">XiRel</a>), 0721915
+(<a href=3D"http://cactuscode.org/community/projects/alpaca/">Alpaca</a>),
+and 0905046/0941653 (PetaCactus).</p>
+
+
+
+<hrule />
+
+<p>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:</p>

+<tt>ET_2010_06</tt> marking this release.  These release branches will
+be updated if severe errors are found.</p>
+
+
+
+<p>This release has been tested on the following systems and
+architectures:</p>
+
+<ul>
+<li>Workstations (AMD, Linux)</li>
+<li>MacBook Pro notebook (Intel, Mac OS X)</li>
+<li><a href=3D"http://www.ncsa.illinois.edu/BlueWaters/modeling.html">Blue D=

+</ul>
+
+<p>The <a href=3D"http://www.cct.lsu.edu/~eschnett/SimFactory/">Simulation
+Factory</a> contains ready-to-use configuration details for more than
+20 additional systems, including most HPC systems
+at <a href=3D"http://www.loni.org/">LONI</a>,
+<a href=3D"http://www.nersc.gov/">NERSC</a>,
+<a href=3D"http://www.rzg.mpg.de/">RZG</a>,
+and <a href=3D"https://www.teragrid.org/">TeraGrid</a>.</p>
+
+<p>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.</p>
+
+
+
+<p>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

+<p>The most recent (and, so far, only) release of the Einstein Toolkit
+  is <tt>ET_2010_06</tt>, code named
+  "<a href=3D"http://en.wikipedia.org/wiki/Bohr-Einstein_debates">Bohr</a>".
+  We expect this version to remain unchanged, save for correcting
+  serious problems that may be detected.  This version should be your
+  first choice if you are new to the Einstein Toolkit, or if you want
+  to perform production simulations.</p>
+
+<p>In addition to the releases, we also have a development version
+  where (unsurprisingly) most of the development occurs.  Our
+  gentlemen's agreement is that the development version should build
+  and run correctly on most of the important platforms at all times,
+  but this may not be the case on a bad day</p>
