One of the efficient methods to calculate in quadruple precision is to use double-double precision routines which use two double precision variables for one quadruple precision variable.

In order to accelerate these routines, this paper implemented double-double precision vector operation of Lis by using AVX instructions instead of SSE2. Our vector operation routines with AVX achieved up to 2.3 times speed up from the same routines with SSE2, when vector data is included in L3 cache.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","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":"2012-07-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"16","bibliographicVolumeNumber":"2012-HPC-135"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":83295,"links":{}}
