The method executes multiple sets of matrix computation with the different tuning parameters to alleviate the performance degradation of the computation with a single tuning parameter. Along with the development of Grid computing technologies, automatically tuned matrix libraries, which enable high performance tuning on several computing platforms, are recently attracting much attention. However, the performance with the existing automatic tuning sometimes degrades dramatically in some cases to cause performance instability problems. Our race-based method is the solutions to such performance instability problems. The experiments of the method for 5 BLAS (Basic Linear Algebra Subprograms) codes on PC (Pentium4, 3.2GHz) show that, in the best case, a 4 member race achieves about 8.6% better in the sense of the lowest-performance in a certain interval.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"102","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":"97","bibliographicIssueDates":{"bibliographicIssueDate":"2004-07-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"81(2004-HPC-099)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":29080,"updated":"2025-01-22T17:44:20.456956+00:00","links":{},"created":"2025-01-18T22:59:01.485954+00:00"}
