Dear Sam, Leo,
thank you for spearheading the latest release of the Einstein Toolkit. This is important work for this community, and we very much appreciate it.
We noticed that Giuseppe Ficarra (in cc) is not listed as contributor nor in the release team. Giuseppe is a co-author of the new Einstein Toolkit thorn "TwoPunctures_BBHSF."
As per best scientific practices to credit scientific work, I would ask you to please add him as contributor and member of the release team on the Einstein Toolkit website and in the release notes.
Best wishes,
Helvi

We are pleased to announce the twenty-sixth release (code name "Karl Schwarzschild") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include:
* kuibit 1.4.0, which, in addition to bug fixes, improves support for working with horizon data, timer data, and higher rank objects (See release notes for more details).
Two new arrangements and thorns have been added:
* The FUKA reader for numerical relativity initial data * TwoPunctures_BBHSF for binary black hole with scalar fields initial data
New capabilities for existing codes:
* Baikal and BaikalVacuum have been updated to have READ/WRITE declarations for automated ghost zone synchronization. Several variable groups (such as RHS variables) are also no longer included in checkpoint/restart operations. * particle_tracerET can now output the particles' four-velocity (contravariant and covariant); added support for binary output format; removed limit on the number of tracer particles
In addition, bug fixes accumulated since the previous release in November 2022 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 code to compute initial data parameters, the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic magneto-hydrodynamics codes GRHydro and IllinoisGRMHD. Data analysis and post-processing is handled by the kuibit library. The Einstein Toolkit also contains a 1D self-force code. 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 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 staff and faculty from five different institutions and host weekly meetings that are open for anyone to join.
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.
For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at http://einsteintoolkit.org https://urldefense.com/v3/__http://einsteintoolkit.org__;!!DZ3fjg!5TkgZVyFsTZLkHtnyQibOcaEiP_lpMBil1TEXu_lpC-s4X2ZSwNUBCVriyx9oJIOvgS2lbgBsqHl6p25Cb3n$, or contact the users mailing list users@einsteintoolkit.org.
The Einstein Toolkit is primarily supported by NSF 2004157/2004044/2004311/2004879/2003893 (Enabling fundamental research in the era of multi-messenger astrophysics).
The Einstein Toolkit contains about 350 regression test cases. On a large portion of the tested machines, almost all of these tests pass, using both MPI and OpenMP parallelization.
Deprecated functionality There are no features marked as deprecated in this release, to be removed in the next release.

How to upgrade from Kowalevski Release (ET_2022_11)
To upgrade from the previous release, use GetComponents with the new thornlist to check out the new version.
See the Download page (http://einsteintoolkit.org/download.html https://urldefense.com/v3/__http://einsteintoolkit.org/download.html__;!!DZ3fjg!5TkgZVyFsTZLkHtnyQibOcaEiP_lpMBil1TEXu_lpC-s4X2ZSwNUBCVriyx9oJIOvgS2lbgBsqHl6oQk8cEg$) on the Einstein Toolkit website for download instructions.
The SelfForce-1D code uses a single git repository; thus, using
git pull; git checkout ET_2023_05
will update the code.
To install Kuibit, do the following:
pip install --user -U kuibit==1.4.0
Machine notes
Supported (tested) machines include:
* Debian, Ubuntu, Fedora, Mint, OpenSUSE, and macOS X installations with dependencies installed as prescribed in the official installation instructions * Deep Bayou * Delta * Expanse * Frontera * Golub * Queen Bee 2 * Queen Bee 3 * Stampede 2 * Summit * Sunrise * SuperMIC * SuperMUC * ThornyFlat
Note for individual machines:
* TACC machines: defs.local.ini needs to have `sourcebasedir = $WORK` and `basedir = $SCRATCH/simulations` configured for this machine. You need to determine $WORK and $SCRATCH by logging in to the machine. * SuperMUC-NG: defs.local.ini needs to have `sourcebasedir = $HOME` and `basedir = $SCRATCH/simulations` configured for this machine. You need to determine $HOME and $SCRATCH by logging in to the machine.
All repositories participating in this release carry a branch ET_2023_05 marking this release. These release branches will be updated if severe errors are found.
