Exploiting Structural Symmetry in a Sparse Partial Pivoting Code
Abstract
This short communication shows how to take advantage of structural symmetry to improve the performance of a class of partial pivoting codes for the LU factorization of large sparse unsymmetric matrices. Experimental results demonstrate the effectiveness of this technique in reducing the overall factorization time.... Sparse LU factorization, Partial pivoting, Structural symmetry.
