Abstract

We devise optimum parallel algorithms for solving a band linear system of equations and for computing the determinant of a band matrix, substantially improving the previous record computational complexity estimates of [E]. All our algorithms are in NC or RNC and processor efficient; almost all of them reach the optimum bound on the potential work (the product of time and processor bounds). Moreover, these algorithms are in NC^1 or RNC^1 if the bandwidth is a constant.
