+
+<p>We are pleased to announce the eighth release (code name
+"<a href=3D"http://en.wikipedia.org/wiki/John_Archibald_Wheeler">Wheeler</a>=
") of the
+Einstein Toolkit, an open, community developed software infrastructure for
+relativistic astrophysics. This release includes various improvements to the
+Cactus flesh, Carpet and GRHydro. In addition, bug fixes accumulated since t=
he
+previous release in November 2014 have been included.</p>
+
+<p>The Einstein Toolkit is a collection of software components and tools for
+simulating and analyzing general relativistic astrophysical systems that bui=
lds
+on numerous software efforts in the numerical relativity community including
+CactusEinstein, the Carpet AMR infrastructure and the relativistic
+magneto-hydrodynamics code GRHydro. The Cactus Framework is used as the unde=
rlying
+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.</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
+six different institutions, and host weekly meetings that are open for anyone
+to join in.</p>
+
+<p>Guiding principles for the design and implementation of the toolkit inclu=
de:
+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.</p>
+
+<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
+&lt;<a href=3D"http://einsteintoolkit.org">http://einsteintoolkit.org</a>&gt=
;.</p>
+
+<p>The Einstein Toolkit is primarily supported by NSF
+1212401/1212426/1212433/1212460 (Einstein Toolkit), and also by 0905046/0941=
653
+(PetaCactus) and 0710874 (LONI Grid).</p>
+
+<p>The Einstein Toolkit contains about 200 regression test cases.  On a large
+portion of the tested machines, almost all of these testsuites pass, using b=
oth
+MPI and OpenMP parallelization.</p>
+
+<h4>The changes between this and the previous release include:</h4>
+
+<p><ul><li><b>Compatibility</b></li></ul></p>
+
+<p><ul><li><b>Larger changes since last release</b></li></ul></p>
+
+<ul>
+ <li>Removed components
+  <ul>
+   <li>ADM
+   <li>LegoExcision
+  </ul>
+ <li>Deprecated components (still included, but don't use for new code)
+  <ul>
+   <li>ADMConstraints (use ML_ADMConstraints instead)
+   <li>ADMCoupling
+   <li>ADMMacros
+   <li>DistortedBHIVP
+   <li>IDAxiBrillBH
+   <li>IDAxiOddBrillBH
+   <li>RotatingDBHIVP
+  </ul>
+ <li>New components:
+  <ul>
+   <li>CactusExamples: 10 small example thorns
+   <li>TestMoL
+   <li>CarpetExtra: 10 test thorns
+   <li>IllinoisGRMHD (not enabled by default, proposed for the next release)
+  </ul>
+ <li>simfactory
+  <ul>
+   <li>updates to many machines
+  </ul>
+ <li>Cactus flesh:
+  <ul>
+   <li>Cactus complex number arithmetic functions are deprecated
+   <li>Drop explicit support for Fortran 77 in Cactus
+   <li>Prevent Cactus from choking on very large parameter files
+   <li>Update to work with Chemora. Not currently used by regular Cactus.
+   <li>The workaround CCTK_DISABLE_RESTRICT for bugs in the Intel compiler
+       is no longer necessary for version newer or equal 14, which is now
+       taken into account.
+   <li>Support for Clang on OSX
+  </ul>
+ <li>MoL: Automatically count number of evolved variables
+ <li>ADMConstraints: remove support for conformal metrics
+ <li>EOS_Omni: new c++ backend
+ <li>GRHydro
+  <ul>
+   <li>rewrite major parts of the code in c++, both versions are still inclu=
ded,
+       the c++ version is not enabled by default yet (see parameter use_cxx_=
code).
+       The default will change for the next release and the Fortran version =
will
+       be removed after that.
+   <li>Lots of smaller changes and bugfixes
+  </ul>
+ <li>Kranc: lots of changes - thorns using Kranc see changes because of this
+ <li>McLachlan: optimizations
+ <li>Carpet
+  <ul>
+   <li>Changes to support accellerators (not used by default)
+   <li>CarpetRegrid2: support Parity Symmetry thorn
+   <li>Carpet: Apply boundary conditions during Restricting
+   <li>Include string null terminator in HDF5 attributes (only important if =
you happen to read them in your own scripts)
+   <li>
+  </ul>
+</ul>
+
+<p><ul><li><b>How to upgrade from Noether (ET_2013_11)</b></li></ul></p>
+
+<p>To upgrade from the previous release, use GetComponents with the new thor=
nlist to check out the new version.</p>
+
+<p>See the <a href=3D"http://einsteintoolkit.org/download/">Download</a> pag=
e on the Einstein Toolkit website for download instructions.</p>
+
+<p><ul><li><b>Remaining issues with this release</b></li></ul></p>
+
+<ul>
+ <li> Certain machines need to be configured specially in Simfactory because=
 the remote directories cannot be determined automatically just from the user=
name.  See the Machine notes below.
+ <li> Recovering with Carpet: Carpet stores metadata (such as the simulation=
 time) only for Carpet::max_timelevels time levels, although it is possible t=
o allocate more time levels. These additional time levels then cannot be reco=
vered; the symptom is an assertion failure during recovery. The solution is t=
o either increase Carpet::max_timelevels, or to decrease the number of active=
 time levels.
+</ul>
+
+<p><ul><li><b>Machine notes</b></li></ul></p>
+
+<p>Supported (tested) machines include:</p>
+
+<ul>
+ <li> Default Debian, Suse and Fedora installations
+ <li> Bethe
+ <li> Bluewaters
+ <li> Carver
+ <li> Datura
+ <li> Gordon
+ <li> Hopper
+ <li> Loewe
+ <li> Lonestar
+ <li> Supermike II
+ <li> Nvidia
+ <li> Orca
+ <li> Philip
+ <li> Queenbee
+ <li> Shelob
+ <li> Stampede (CPU)
+ <li> Supermuc
+ <li> Titan
+ <li> Trestles
+ <li> Zwicky
+</ul>
+
+<ul>
+ <li> LoneStar and Stampede: defs.local.ini needs to have sourcebasedir =3D =
$WORK and basedir =3D $SCRATCH/simulations configured for this machine.  You =
need to determine $WORK and $SCRATCH by logging in to the machine.</li>
+</ul>
+
+<p>All repositories participating in this release carry a branch ET_2014_05
+marking this release.  These release branches will be updated if severe
+errors are found.</p>
