IFPACK is a preconditioner package for solving linear systems of equations. IFPACK provides a collection of incomplete factorization preconditioners that can be used in conjunction with almost any iterative solver package to accelerate the convergence of iterative methods. IFPACK provides the solution of linear systems of equations arising in engineering and scientific appplications. IFPACK is especially suited for computational fluid dynamics applications, electromagnetics, and other forms of applications that must solve partial differential equations implicitly. It is meant to work in conjunction with an iterative solver such as those provided by AztecOO. IFPACK implements a suite of incomplete factorization algorithms that compute an approximate factorization for a given user matrix. This type of factorization is effective as a preconditioner for iterative methods that solve a system of linear equations. IFPACK is written in C++ using object oriented programming techniques.
