A note on the parallel Cholesky factorization of wide banded matrices


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)
