| + | 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. |

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. |

| − | * 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.

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 Einstein Toolkit contains about 200 regression test cases. On a large portion of the tested machines, almost all of these test suites pass, using both MPI and OpenMP parallelization.
