PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication. Several sample scientific applications, as well as various papers and talks, demonstrate the features of the PETSc libraries. Look for these in the menu on the right.

The current version of PETSc is 2.1.0; released April 11,2001.

PETSc is intended for use in large-scale application projects, and several ongoing computational science projects are built around the PETSc libraries. With strict attention to component interoperability, PETSc facilitates the integration of independently developed application modules, which often most naturally employ different coding styles and data structures.

PETSc is easy to use for beginners. Moreover, its careful design allows advanced users to have detailed control over the solution process. PETSc includes an expanding suite of parallel linear and nonlinear equation solvers that are easily used in application codes written in C, C++, and Fortran. PETSc provides many of the mechanisms needed within parallel application codes, such as simple parallel matrix and vector assembly routines that allow the overlap of communication and computation. In addition, PETSc includes growing support for distributed arrays. Features include:

  • Parallel vectors
    • scatters
    • gathers
  • Parallel matrices
    • several sparse storage formats
    • easy, efficient assembly.
  • Scalable parallel preconditioners
  • Krylov subspace methods
  • Parallel Newton-based nonlinear solvers
  • Parallel timestepping (ODE) solvers
  • Complete documentation
  • Automatic profiling of floating point and memory usage
  • Consistent interface
  • Intensive error checking
  • Portable to UNIX and Windows
  • Over one hundred examples
  • PETSc is supported and will be actively enhanced for the next several years.
