From Oct 31st to Nov 3rd, maintainers, developers and users of the Einstein Toolkit met in Baton Rouge, LA, at the Center for Computation and Technology, to review the current status of the project, to discuss about future directions and to also actually work on getting there.
Over twenty local, national and international researchers discussed topics like infrastructure improvements due to data-driven scheduling, GPU-support within Cactus, an improved build system or a general elliptic solver interface, as well as improvements to the physics-related parts of the project, like the interface to different equations of state, different implementations of magneto-hydrodynamics and radiation transport.
After almost four exciting but also exhausting days, it became clear that while a lot was accomplished during the workshop, even more will be accomplished in the near or mid-term future.

New Einstein Toolkit release "Maxwell"
We are pleased to announce the fourth release (code name "Maxwell") of the Einstein Toolkit, an open, community developed software infrastructure for relativistic astrophysics. This release includes substantial changes to the underlying AMR infrastructure Carpet and the simfactory tool. GRHydro is now officially released with support for magnetohydrodynamics. In addition, bug fixes accumulated since the previous release in April 2011 have been included.
The Einstein Toolkit is a collection of 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 Carpet AMR infrastructure and
the relativistic hydrodynamics code GRHydro (an updated and extended version of the public release of the Whisky code). 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.
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 host weekly meetings that are open for anyone to join in.
Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers.

The Einstein Toolkit is primarily supported by NSF 0903973/0903782/0904015 (CIGR), and also by NSF 0701566/0855892 (XiRel), 0721915 (Alpaca), 0905046/0941653 (PetaCactus) and 0710874 (LONI Grid).

New Einstein Toolkit release "Curie"
We are pleased to announce the third release (code name "Curie") of the Einstein Toolkit, an open, community developed software infrastructure for relativistic astrophysics. This release changed the equation of state interface from two competing (EOS_Base and EOSG_Base, also known as the old and the general EOS interface), to a completely new interface called EOS_Omni, also adding support for tabulated, microphysical EOSs in the process. In addition, bug fixes accumulated since the previous release in November 2010 have been included, and the testsuites have been checked also using OpenMP.
