PETSc (Portable, Extensible Toolkit for Scientific Computation) is a high-performance scientific computing library developed by Argonne National Laboratory. PETSc provides:

• Linear equation solvers (Krylov subspace methods, direct solvers).
• Nonlinear equation solvers (Newton-type methods with line search and trust region).
• Time steppers and ODE/DAE integrators for dynamic system simulation.
• Data structures for sparse matrices, distributed arrays, and mesh management.
• MPI parallel computation for large-scale distributed processing.
• Multiple preconditioner options (ILU, ICC, SOR, AMG via HYPRE, etc.)
• Compatibility with Intel, AMD, and ARM architectures. Learn more at PETSc⁠.
