The scheme differs from conventional ones in that it stripes across nodes a file in one block size while it stripes the file's replica in a different size. The authors expect the scheme allows independent tuning of the two sizes, the former for performance in normal operation and the latter for load distribution in reduced operation. Results of preliminary evaluation of the scheme applied to a parallel full-text search system shows that the scheduler must have some preference for originals over copies in order to alleviate contention for disk cache.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"64","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":"59","bibliographicIssueDates":{"bibliographicIssueDate":"1999-08-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"66(1999-HPC-077)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":29546,"updated":"2025-01-22T17:29:34.239313+00:00","links":{},"created":"2025-01-18T22:59:22.065635+00:00"}
