を用いて同等のシステムを構築した場合のデータアクセスの性能と運用方法を比較した。性能面では ASTER アプリケーションのデータ処理を解析した上で、各ストレージシステムでのアプリケーションの実行性能を比較した。運用面では故障に対する備え方、メンテナンスの作業内容や課題を比較した。これらの調査により、より大規模な衛星観測データの保存システム、あるいは類似アプリケーションのためのストレージを構築するための指針を得た。","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"An infrastructure to store hundreds terabytes of satellite observation data in the online hard disk drives, and to allow geosciences researchers to access the data from anywhere at anytime, is highly

A backend storage system on that infrastructure needs to meet the requirements of huge data storing capacity and high-performance data access. In order to design and build this kind of HPC storage system, Gfarm and Lustre were compared by the ASTER satellite image data application. In terms of the performance comparison, the data processing part was profiled, and the execution time of the major data conversion program was measured on both storage systems. In addition, configuration for fault tolerance, daily maintenance and issues for operation were compared between the two systems. This study provides the information to build a larger storage system for the satellite image data, and other applications which have similar data access patterns to the ASTER application.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"284","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"279","bibliographicIssueDates":{"bibliographicIssueDate":"2007-08-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"80(2007-HPC-111)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
