The Portable, Extensible Toolkit for Scientific Computation ( PETSc , pronounced PET-see) developed by Argonne National Laboratory is a scalable software for solving partial differential equations

Components provided by PETSC:

• "Scalable Nonlinear Equations Solvers (SNES)"
• "Timestepping" (TS) for ordinary differential equations and differential algebraic equations
• Krylov subspace method (Krylov subspace "KSP")
• Preconditioning (preconditioner "PC")
• Matrices , Vectors and Index Sets (IS)

One of the developers is Bill Gropp .
