### Abstract

This document describes a collection of three related ANSI C subroutine libraries for solving sparse linear systems of equations AX = B. Here A is a square, nonsingular, n \Theta n sparse matrix, and X and B are dense n \Theta nrhs matrices, where nrhs is the number of right-hand sides and solution vectors. Matrix A need not be symmetric or definite; indeed, SuperLU is particularly appropriate for matrices with very unsymmetric structure. All three libraries use variations of Gaussian elimination optimized to take advantage both of sparsity and the computer architecture, in particular memory hierarchies (caches) and parallelism. In this introduction we refer to all three libraries collectively as SuperLU. The three libraries within SuperLU are as follows. Detailed references are also given (see also [19]).
