@conference {832, title = {Computing Least Squares Condition Numbers on Hybrid Multicore/GPU Systems}, booktitle = {International Interdisciplinary Conference on Applied Mathematics, Modeling and Computational Science (AMMCS)}, year = {2014}, month = {2014-08}, address = {Waterloo, Ontario, CA}, abstract = {This paper presents an efficient computation for least squares conditioning or estimates of it. We propose performance results using new routines on top of the multicore-GPU library MAGMA. This set of routines is based on an efficient computation of the variance-covariance matrix for which, to our knowledge, there is no implementation in current public domain libraries LAPACK and ScaLAPACK.}, author = {Marc Baboulin and Jack Dongarra and Remi Lacroix} }
