paper presents a streaming SIMD extensions (SSE)-based method for increasing the throughput of secure hash algorithm (SHA)-1 computation for deduplicated storage systems. Our method exploits the data independency between different input files, realizing SSE-based vectorization and OpenMP-based multithreaded execution. In experiments, we achieve a speedup of 1.5 times over a previous method that parallelizes computation for a single file. This leads to an efficiency of 93% and the measured throughput reaches 80 Gbps, which is higher than the effective bandwidth of the PCI Express bus. Thus, we think that our method eliminates a performance bottleneck of deduplicated storage systems.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-03-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"31","bibliographicVolumeNumber":"2012-HPC-133"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:35:36.608245+00:00","id":81366,"links":{}}
