Parallel Two-Sided Matrix Reduction to Band Bidiagonal Form on Multicore Architectures

The objective of this paper is to extend, in the context of multicore architectures, the concepts of tile algorithms [Buttari et al., 2007] for Cholesky, LU, and QR factorizations to the family of two-sided factorizations. In particular, the bidiagonal reduction of a general, dense matrix is very of...
