After the scalar optimization of the NS3D code, the code is parallelized using the various parallel programming languages and the performance is evaluated. The calculation part for the NS3D code is obtained a good parallel performance using the various parallel programming languages and the hybrid version (MPI + OpenMP and XPFortran + OpenMP). However, the communication part of the NS3D code indicates that the performance of the XPFortran (+ OpenMP) version is better than that of the MPI (+ OpenMP) version. It is necessary to improve the performance of the MPI (+ OpenMP) version. The performance ratio between the sequential calculation and the XPFortran + OpenMP using 1,440 CPUs is about 845.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469002","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-04-012","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 穣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松尾, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kobayashi, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yuichi","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":"2020-01-16"}],"displaytype":"detail","filename":"48469002.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469002.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6442/files/48469002.pdf"},"version_id":"02627cd0-0733-461f-9438-71aee4f4bbc0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"NS3Dコード","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"並列化","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_scheme":"Other"},{"subitem_subject":"プログラミング言語","subitem_subject_scheme":"Other"},{"subitem_subject":"性能向上","subitem_subject_scheme":"Other"},{"subitem_subject":"最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"コンパイラ","subitem_subject_scheme":"Other"},{"subitem_subject":"NS3D code","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parallelization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"programming language","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"performance improvement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"compiler","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"NS3Dコードの各種並列化言語を用いた並列化による性能向上について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NS3Dコードの各種並列化言語を用いた並列化による性能向上について"}]},"item_type_id":"5","owner":"1","path":["1073","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6442","relation_version_is_last":true,"title":["NS3Dコードの各種並列化言語を用いた並列化による性能向上について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:55:45.173372+00:00"}
