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.

If you would like to advertise your thorn without including in the official Einstein Toolkit release then you can send email to this list, we also try and track public modules that are not (yet) part of the Einstein Toolkit distribution in https://docs.einsteintoolkit.org/et-docs/Thorns_we_know_of There's no specific coding style guide. We do include a clang-format style file in https://bitbucket.org/cactuscode/cactus/src/master/.clang-format which can be used with clang-format (https://clang.llvm.org/docs/ClangFormat.html) to format code. There is also a (separate and different) code style document that was included in Cactus in the maintainers's guide: https://bitbucket.org/cactuscode/cactus/src/master/doc/MaintGuide.pdf Yours, Roland > [CAUTION: Non-UBC Email] > > Dear Einstein Toolkit team, > My name is Vinicius Ramos Rodrigues, and I am currently developing a > research module (thorn) intended for use with the Einstein Toolkit in the > context of numerical relativity research. > 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.

Registration has opened for the 2026 North American ETK Workshop and School June 15-18, Urbana, Illinois National Center for Supercomputing applications, Room 1040. Release - Gallery runs start in April. - Peter to review the BHNS. - Tests should be run on various clusters. - CarpetX doesn?t work with the latest version of CUDA. - No progress on CanudaX. Questions on the mailing list: Range of parameters works on some machine but not others. Buggy compiler?? Suggestion, run it again with a new compiler. Open tickets by update time: 2908: Ready for review. 2922: Big headache. AMReX made a fundamental change to their database. No easy solution. 2913: Needs more work. 2903: Why no PR? Misc.
