In this study, we investigate and evaluate the performance of CPU operation and memory access of the system by using an unstructured NS solver, and found that the new system has an expected high performance compared with the previous system. However, we also found that for high efficiency to applications, the issues on load unbalance and recursive reference can be further considered.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064379000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RM-09-002","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター計算機運用・利用技術チーム"},{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター計算機運用・利用技術チーム"},{"subitem_text_value":"宇宙航空研究開発機構航空プログラムグループ国産旅客機チーム"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Computing resource Management Team, JAXA's Engineering Digital Innovation Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Computing resource Management Team, JAXA's Engineering Digital Innovation Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Civil Transport Team, Aviation Program Group, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂下, 雅秀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松尾, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村山, 光宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakashita, Masahide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murayama, Mitsuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"64379000.pdf","filesize":[{"value":"649.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64379000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2586/files/64379000.pdf"},"version_id":"417f2307-cef7-4aa8-80dc-ad4436dfb0b3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Supercomputing, OpenMP, MPI, Navier-Stokes, CFD, unstructured mesh","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"非構造格子NSソルバによるJAXA統合スパコン(JSS)の性能評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非構造格子NSソルバによるJAXA統合スパコン(JSS)の性能評価"}]},"item_type_id":"3","owner":"1","path":["1239","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2586","relation_version_is_last":true,"title":["非構造格子NSソルバによるJAXA統合スパコン(JSS)の性能評価"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:19:35.024081+00:00"}
