Efficient one-sided Jacobi algorithms for singular value decomposition and the symmetric eigenproblem
Bing Bing Zhou, Richard P. Brent, Margaret Kahn · 2002
A method which uses one-sided Jacobi to solve singular valve decomposition and the symmetric eigen-valve problem in parallel is presented. We describe a parallel ring ordering for one-sided Jacobi computation. One distinctive feature of this ordering is that it can sort column norms in each sweep, which is very important to achieve fast convergence. Experimental results on both the Fujitsu AP1000 and the Fujitsu VPP500 are reported.>
