Cleve Ashcraft, Stanley C. Eisenstat, Joseph W. Liu, Andrew H. Sherman · 1990
Abstract : The solution of large sparse systems of linear is an important application of parallel computers. In this paper, we give a unified presentation and compare the performance of three distributed schemes to compute the Cholesky factor of a large sparse symmetric positive definite matrix on a local-memory parallel processor.
