The parallel two-sided block-Jacobi singular value decomposition (SVD) algorithm with dynamic ordering, originally proposed in [Parallel Comput. 28 (2002) 243-262], has been extended with respect to the blocking factor '.

One way, how to speed up the computation of the singular value decomposition of a given matrix A 2 C mΓn ; m P n, by the parallel two-sided block-Jacobi method, consists of applying some pre-processing steps that would concentrate the Frobenius norm near the diagonal. Such a concentration should hop
