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. This includes CactusEinstein, the Carpet AMR infrastructure and the relativistic magneto-hydrodynamics codes GRHydro and IllinoisGRMHD. For parts of the toolkit, 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 magneto-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, staff and faculty from six 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 changes between this and the previous release include:
* A new equation of state (EOS) interface was introduced, replacing both EOS_Base and EOSG_Base. It was designed with efficiency in mind, and combines all EOSs into one single thorn. All previously supported EOSs are now provided by EOS_Omni. The other EOS thorns are still maintained, but their support will be dropped at the next Einstein Toolkit release.
 
* The location of the GetComponents script changed (now hosted at github).
 
* The MHD implementation within GRHydro saw several updates, but is still disabled by default.
 
* Since spacetime-excision is not actively used anymore and not supported by an evolution thorn within the ET, this will be the last time LegoExcision will be part of an Einstein Toolkit release. Please consider other options if you rely on it, or let us know so that we can reconsider this decision.
 
* This release still ships with the Perl-version of Simfactory, but includes updated machine configurations and some bug fixes.
 
* Some external libraries now check for the parallel usage of the old library interface (e.g. HDF5=yes) and abort in this case. The new way (e.g. HDF5_DIR=...) is not compatible with the old way to specify libraries. If you get errors because of this you have to remove one of the two specifications from your optionlist.

This release comprises the following tools, arrangements, and thorns.  Each

All repositories participating in this release carry a branch
 
"ET_2010_11" 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:
 
 
        Workstations (Intel, Linux)
 
        MacBook Pro notebook (Intel, Mac OS X)
 
        Blue Drop, NCSA (Power 7, Linux)
 
        Damiana, AEI (Intel Woodcrest cluster, Linux)
 
        Kraken, NICS (Cray XT5, Linux)
 
        Philip, LSU (Intel cluster, Linux)
 
        Queen Bee, LONI (Intel cluster, Linux)
 
        Ranger, TACC (AMD cluster, Linux)
 
 
The Simulation Factory contains ready-to-use configuration details for
 
more than 20 additional systems, including most HPC systems at DOE,
 
LONI, TeraGrid, and RZG.
 
 
The Einstein Toolkit thorns contain 132 regression test cases.  While
 
all test cases pass on some 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 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@einsteintoolkit.org>.
 
 
 
 
The changes between this and the previous release include (not complete):
 
* Several Libraries can now be build in parallel-make mode, increasing compilation speed on some machines a lot.
 
* Several Libraries now clean up intermediate files, often using considerably less disk space per configuration.
 
* GRHydro includes (disabled, not yet finished) support for MHD. Don't try to use it yet, and don't get confused about that code.
 
* Several Libraries have been updated (ExternalLibraries)
 
* Simfactory received several updates, and this will likely be the last release with the Perl version.
 
* The links in the Reference manual now work (again).
 
* A lot of other bugs and testsuites were corrected.

Unnamed (ET_2016_11)

NOTE: This release text is work in progress, meant for an upcoming release of the Einstein Toolkit, not of an already released version.

We are pleased to announce the fourteenth release (code name "Unnamed") of the Einstein Toolkit, an open, community developed software infrastructure for relativistic astrophysics. This release includes, among other things, TODO. In addition, bug fixes accumulated since the previous release in May 2016 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. This includes CactusEinstein, the Carpet AMR infrastructure and the relativistic magneto-hydrodynamics codes GRHydro and IllinoisGRMHD. For parts of the toolkit, 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 magneto-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, staff and faculty from six 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.
