As a result, when solving a relatively small system of equations (order 1000), we have obtained sustained performance of 6.54 GFLOPS with a single processor and 20.5 GFLOPS with four processors on Hitachi's S-3800 shared memory vector parallel supercomputer.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"80","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"73","bibliographicIssueDates":{"bibliographicIssueDate":"1995-03-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"29(1994-ARC-111)","bibliographicVolumeNumber":"1994"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
