In this paper, we consider a parallelization of singular value computation algorithm by the Lotka--Volterra system. The singular value computation plays an important role in, for example, data search systems and image data processings. A large--scale processing for the advanced applications needs a better algorithm with respect to both convergence speed and numerical accuracy. A straightforward data--splitting method invokes interprocessor communications every step. As a result, it parallelizes the algorithm inefficiently. We here propose a parallel version of the algorithm with non--blocking communications, which enables us to introduce processing in the waiting. Numerical results of the parallel algorithm implemented with the Message Passing Interface on a distributed--memory computer with 32 processors are also presented.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"18","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"13","bibliographicIssueDates":{"bibliographicIssueDate":"2004-12-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"128(2004-HPC-100)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":29058,"updated":"2025-01-22T17:45:27.224259+00:00","links":{},"created":"2025-01-18T22:59:00.528826+00:00"}
