In this paper we give evidence to show that in one-sided Jacobi SVD computation the sorting of column norms in each sweep is very important. An efficient parallel ring Jacobi ordering for computing singular value decomposition is described. This ordering can generate n(n -1)/2 different index pairs

We present two new algorithms for computing the Jacobi Symbol: the right-shift and left-shift k-ary algorithms. For inputs of at most n bits in length, both algorithms take O(n 2 / log n) time and O(n) space. This is asymptotically faster than the traditional algorithm, which is based in Euclid's al
Olariu, S. and Z. Wen, An efficient parallel algorithm for multiselection, Parallel Computing 17 (1991) 689-693. The problem of multiselection arises frequently in databases. Here, given an unordered set S of n records and a sequence of m integers 1 ~< ql < q2 < .--< qm ~< n we are interested in an
