We are developing Pwrake, a parallel and distributed workflow system, to enable parallel and distributed processing without special programming technique. Pwrake is based on Rake, a Ruby version of make command. Rake has the feature that workflow definition can be written in programming script, and it brings the power of writing complex scientific workflows. Pwrake provides Rake with functions for parallel and distributed execution and the support for Gfarm filesystem. The workflow of Montage, astronomical image processing software, is written in Rake and its performance is measured using Pwrake. The result shows that Gfarm provides a scalable performance, and that the use of local storage improves performance by 14%. In addition, the result using clusters at two sites also shows a scalable performance improvement.","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: AA0065236009","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-RR-11-007","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":"1349-1113","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":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"筑波大学計算科学研究センター : 科学技術推進機構戦略的創造研究推進事業"},{"subitem_text_value":"筑波大学計算科学研究センター : 科学技術推進機構戦略的創造研究推進事業"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Center for Computational Physics, University of Tsukuba : Core Research of Evolutional Science & Technology, Japan Science and Technology Agency (JST)(CREST)"},{"subitem_text_language":"en","subitem_text_value":"Center for Computational Physics, University of Tsukuba : Core Research of Evolutional Science & Technology, Japan Science and Technology Agency (JST)(CREST)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 昌宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"建部, 修見"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tatebe, Osamu","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":"65236009.pdf","filesize":[{"value":"968.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65236009.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2026/files/65236009.pdf"},"version_id":"7dad7f62-c7a6-4588-860a-e657702825ff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Scientific Workflow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Distributed System","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Astronomy Data","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":"並列分散ワークフローシステムPwrakeによる大規模データ処理","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"並列分散ワークフローシステムPwrakeによる大規模データ処理"}]},"item_type_id":"3","owner":"1","path":["99","1407","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2026","relation_version_is_last":true,"title":["並列分散ワークフローシステムPwrakeによる大規模データ処理"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:30:07.404377+00:00"}
