A note on the parallel Cholesky factorization of wide banded matrices

Abstract

In this note, we will describe two algorithms for factoring symmetric positive definite band matrices. Both algorithms are designed for a p x p array of processors with local memory with p ~< O(m), where m is the semibandwidth of the matrix. The p × p model is appropriate for the Ametek Series 2010, which is a mesh, or the popular hypercube architectures… (More)
