However, there are two major issues with multicore technologies: 1) how to make full use of modern multicore CPU capability with reduced user workload, and 2) how to achieve better scalability up to a high degree of parallelism for memory-intensive applications such as computational fluid dynamics. First, the multicore-based massively parallel cluster of the Japan Aerospace Exploration Agency (JAXA) supercomputer system, which uses the Fujitsu FX1 as the core computer, is described. Notable features such as a high-speed barrier network, enhanced memory bandwidth, and an integrated mechanism to hide latency, i.e., the integrated multicore parallel architecture, which comprises a hardware barrier, L2 cache shared among cores, and an associated automated parallelization complier, are described. Second, the process to achieve significantly high sustained performance (>90%, high-performance Linpack benchmark) on the multicore CPU cluster system is explained. Finally, performance measurement results for JAXA applications are provided.","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_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1530011000","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-14-011E","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(JAXA)"}]},"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セキュリティ・情報化推進部スーパーコンピュータ活用室(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構セキュリティ・情報化推進部スーパーコンピュータ活用室(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構セキュリティ・情報化推進部スーパーコンピュータ活用室(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Supercomputer Office, Security and Information Systems Department, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Supercomputer Office, Security and Information Systems Department, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Supercomputer Office, Security and Information Systems Department, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松尾, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤田, 直行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高木, 亮治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Naoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takaki, Ryoji","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":"AA1530011000.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1530011000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2476/files/AA1530011000.pdf"},"version_id":"17b45ad1-cfd7-4671-93f9-029f9bc00ba2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Sustained performance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Scalability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Multicore","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Massively parallel cluster system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"JAXA supercomputer system","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"High Sustained Performance and Scalability on a Multicore-Based Massively Parallel Cluster of JAXA Supercomputer System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High Sustained Performance and Scalability on a Multicore-Based Massively Parallel Cluster of JAXA Supercomputer System","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1139","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-10"},"publish_date":"2015-04-10","publish_status":"0","recid":"2476","relation_version_is_last":true,"title":["High Sustained Performance and Scalability on a Multicore-Based Massively Parallel Cluster of JAXA Supercomputer System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:21:56.645280+00:00"}
