Dear PETSc/TAO Community, We are soliciting PETSc users to share their usage experiences, application successes, and ongoing challenges in an online Zoom Birds-of-a-Feather (BoF) session, to be held between February 10~12, 2026. We are seeking approximately five short user presentations, each consisting of a 5-minute talk followed by 2 minutes of questions. If you are interested in presenting, please contact [email protected] with your talk title, a brief abstract, and your preferred time slot (11:00 AM, 1:00 PM, or 3:00 PM EST).
The BoF is hosted by the Consortium for the Advancement of Scientific Software (CASS <https://urldefense.us/v3/__https://cass.community/__;!!G_uCfscf7eWS!cGKRFA2mxYbJqy-t7sHjX6cRv9WDCHQ-N-ixpHDjW-ay1XCEKAIN7P0VeudLwn37g34P0Ye6pzzV8MvZeFz00D_bMBfS$ >) and led by the PESO <https://urldefense.us/v3/__https://pesoproject.org/__;!!G_uCfscf7eWS!cGKRFA2mxYbJqy-t7sHjX6cRv9WDCHQ-N-ixpHDjW-ay1XCEKAIN7P0VeudLwn37g34P0Ye6pzzV8MvZeFz00J2p4TVU$ > (Partnering for Scientific Software Ecosystem Stewardship) project. The PETSc session will last 90 minutes and will take place on one day between February 10 and 12, 2026 (exact date to be finalized). Please note that the session will not be recorded. Our preferred time slot is 11:00 AM EST (5:00 PM UTC) to better accommodate European participants, although alternative options at 1:00 PM or 3:00 PM EST are also under consideration. In addition to user presentations, during the session, 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 will be posted once the program is finalized. Thank you, and we look forward to your participation. Junchao Zhang On behalf of the PETSc team
