Overview#

PETSc, the Portable, Extensible Toolkit for Scientific Computation, is intended for use in large-scale application projects. PETSc includes a large suite of parallel linear, nonlinear equation solvers and ODE integrators that are easily used in application codes written in C, C++, Fortran and Python. 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 support for managing parallel PDE discretizations
