PETSc 3.22#
PETSc, the Portable, Extensible Toolkit for Scientific Computation, pronounced PET-see (/ˈpɛt-siː/), is for the scalable (parallel) solution of scientific applications modeled by partial differential equations (PDEs). It has bindings for C, Fortran, and Python (via petsc4py). PETSc also contains TAO, the Toolkit for Advanced Optimization, software library. It supports MPI, and GPUs through CUDA, HIP, Kokkos, or OpenCL, as well as hybrid MPI-GPU parallelism; it also supports the NEC-SX Tsubasa Vector Engine. Immediately jump in and run PETSc code Tutorials, by Mathematical Problem.
PETSc is developed as open-source, requests and contributions are welcome.
News:
PETSc is now on BlueSky.
News:
The 2025 PETSc Annual User Meeting will take place May 20-21, 2025 in Buffalo, New York, USA, with tutorials on May 19th.
News: Mrs Hong Zhang, who has been a PETSc developer for twenty-five years and mentored many students and future PETSc developers, has retired.
News: PETSc is associated with NumFOCUS, a 501(c)(3) nonprofit supporting open code and reproducible science, through which you can help support PETSc.
