products of sparse matrix and vectors, which are often seen in application programs such as structural analysis code using finite element methods, the higher ratio of memory bandwidth and floating-point rate (B/Flop) is required by the program. A scalar machine is difficult to obtain high performance in a CPU due to its low ratio of B/Flop. We are developing the K computer as a 10 Peta scale super computer and have to demonstrate its performance by using real applications. Application programs Seism3D and FrontFlow/blue, which have products of sparse matrix and vectors as kernels in the programs, are suitable to show how to obtain higher performance by tuning them to the K computer. In this paper, techniques on how to estimate performance of the codes and to tune them are presented. Results on performance evaluation of tuning versions are also described.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"ハイパフォーマンスコンピューティングと計算科学シンポジウム論文集"}],"bibliographicPageStart":"23","bibliographicIssueDates":{"bibliographicIssueDate":"2012-01-17","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2012"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":80214,"links":{}}
