In this paper we employ Householder transformations and Givens rotations to solve the updated and downdated OLM, using a massively parallel SIMD computer. Some of our methods are modified versions of serial algorithms published previously while others appear for the first time. The execution time models of all algorithms are studied and compared. | URI: | https://hdl.handle.net/20.500.14279/14720 | ISSN: | 17445779 | DOI: | 10.1080/10637199308915444 | Rights: | © Taylor & Francis | Type: | Article | Affiliation : | City, University of London Queen Mary and Westfield College |
