## Parallel Direct Methods for Sparse Linear Systems

Carey, ed. Ng and B. Schenk, K. Sloot, M. The focus is on direct methods for solving systems of linear equations; iterative methods and solvers for eigenvalue problems are beyond the scope of this book.

The goal is to impart a working knowledge of the underlying theory and practice of sparse matrix algorithms, so that you will have the foundation to understand more complex but faster algorithms.

Methods that operate on dense submatrices of a larger sparse matrix multifrontal and supernodal methods are much faster, but a complete sparse matrix package based on these methods can be tens of thousands of lines long. Trying to understand the sparse matrix technique by starting with such huge codes is a daunting task.

To overcome this obstacle, a sparse matrix package, CSparse, has been written specifically for this book. Although simple and concise, it is based on recently developed methods and theory. All of CSparse is printed in this book.

Take your time to read and understand these codes; do not gloss over them. You will find them much easier to comprehend and learn from than their larger yet faster cousins. The larger packages you may use in practice are based on much of the theory and some of the algorithms presented more concisely and simply in CSparse.
