Dear PETSc/TAO Community, Thank you to those who have already signed up to present their work at the upcoming PETSc Birds-of-a-Feather (BoF) session. We are still seeking additional user presentations. The PETSc BoF will be held online via Zoom on *February 11, 2026, from 11:00 AM to 12:30 PM U.S. Eastern Time*. Please note that this session will not be recorded. We are seeking approximately five user presentations, each consisting of a 5-minute talk followed by 2 minutes of questions. We currently have four and can still accept one or two presentations. If you are interested, please contact [email protected] with your talk title and a brief abstract. The BoF is hosted by the Consortium for the Advancement of Scientific Software (CASS <https://urldefense.us/v3/__https://cass.community/__;!!G_uCfscf7eWS!ccFV4rPG... >) and led by the PESO <https://urldefense.us/v3/__https://pesoproject.org/__;!!G_uCfscf7eWS!ccFV4rP... > (Partnering for Scientific Software Ecosystem Stewardship) project. The CASS BoF events will take place from February 10–12, 2026. In addition to user presentations, during the PETSc BoF, PETSc developers will highlight recent advances developed following the Exascale Computing Project, including the new PETSc Fortran bindings, PetscRegressor, TaoTerm, updates to PETSc GPU backends, mixed-precision support in PETSc/MUMPS, and integration with OpenFOAM, among other topics. The program will also include an open discussion of emerging PETSc research directions, such as leveraging agentic artificial intelligence to enhance and exploit the PETSc knowledge base. The BoF will provide insight into PETSc’s near-term development roadmap and offer a forum for user feedback on desired features and improvements. Active participation and questions from the audience are strongly encouraged, enabling the PETSc team to better align future development with community needs. The agenda and Zoom link will be shared once the program is finalized. Thank you, and we look forward to your participation. Junchao Zhang On behalf of the PETSc Team
