The module is being designed as a processual stress-energy sector compatible with the Toolkit infrastructure, including coupling through TmunuBase and evolution with MoL/BSSN-based setups. My goal is to make this implementation available for research use and to ensure that it follows the most appropriate technical and community standards for the Einstein Toolkit ecosystem. I would like to ask for your guidance on the best path for doing this. In particular, I would appreciate advice on: whether there is a recommended procedure for sharing a new research thorn with the community, whether there are preferred coding, documentation, or testing requirements before such a thorn is made available, and whether contribution through a public repository or another review process would be the most suitable route. If useful, I can also provide a short technical summary of the module, its equations, intended use case, and current implementation status. Thank you very much for your time and for maintaining such an important resource for the numerical relativity community.

This was very relevant. With loaded modules related to GCC-13.3.0 (and GCC-14.3.0), the error is occurring, while for GCC-12.3.0, the range is working as expected. This is compatible with the experiment on other clusters and on my work station, which have lower versions of gcc as well. What should be made of that knowledge? Should I file a ticket?

The registration is now open at the website https://benasque.org/2026relativity/?where you can find further information. The goal of the workshop is to foster new ideas and collaborations by bringing together experts across different disciplines, including gravity, gravitational wave astrophysics, numerical and mathematical relativity. We plan for only two talks per day, with ample time for informal discussions, sessions and collaborations. We aim at creating a diverse and inclusive meeting that thrives through communication and discussion, and we would greatly welcome participation and contributions from different communities, as well as researchers at different career stages. Invited speakers include: Josu Aurrekoetzea - Miguel Bezares - Marina de Amicis - Elena Georgi - Archisman Ghosh - Ruth Gregory - Kelly Holley-Bockelmann - Alex Jenkins - Elisa Maggio - Simone Mastrogiovanni - Julio Parra-Martinez - Rafael Porto - B. Sathyaprakash - Thomas Sotiriou - Leonard Susskind - Rodrigo Vicente - Nils Vu - Silke Weinfurtner - Sebastian Zell We look forward to welcoming you to Benasque, Helvi On behalf of the organisers (D.

The Workshop will be held at the University of Illinois Urbana-Champaign from 15-18 June 2026 and will also be accessible online. The Workshop will provide an opportunity for researchers and students to learn about the Einstein Toolkit, a community-driven software platform comprising core computational tools that support and advance research in relativistic astrophysics and gravitational physics. It will feature a mix of talks and tutorials, including introductory sessions for new users as well as advanced topics for experienced users. We will offer several tutorials on CarpetX and science codes based on CarpetX, the new GPU-enabled driver in the Einstein Toolkit ecosystem. The talks will likewise support new users while highlighting exciting science cases and the latest developments in numerical relativity. The Workshop will be fully hybrid, with all in-person sessions broadcast live over Zoom for online participants. Details and registration are available on our website: https://etksummerschool2026.illinois.edu/ The relevant deadlines are as follows: In-person registration: May 8, 2026 Online registration: June 14, 2026 Travel support request: April 19, 2026 We hope to see you in Urbana-Champaign in June 2026.
