According to our study, it is highly possible that using ring algorithm on multi-core PC cluster system causes Head-of-line (HoL) blocking in network switch. We propose 2-level ring algorithm that can reduce the chance of HoL blocking significantly. The experimental results show that 2-level ring algorithm realizes higher network bandwidth compared to ring algorithm by 24% at maximum and improves the performance of NPB FT and IS by 7% at maximum.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"177","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"166","bibliographicIssueDates":{"bibliographicIssueDate":"2010-09-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:29:50.801075+00:00","id":70779,"links":{}}
