Abstract
This paper describes a parallel implementation of LDL(T) factorization on a distributed-memory parallel computer. Specifically, the parallel LDL(T) factorization procedure is based on a row-oriented sparse stor age scheme. In addition, a strategy is proposed for the parallel solut ion of a triangular system of equations. The strategy is to compute th e inverses of the dense principal diagonal block submatrices of the fa ctor L, stored in a row-oriented structure. Experimental results for a number of finite element models are presented to illustrate the effec tiveness of the parallel solution schemes.
