In particular, performance degradation in meta-data accesses leads to poor storage performance across applications running at the same time. We herein focus on two representative performance problems, high load and slow response of a meta-data server, through analysis of meta-data server activities using file system performance metrics on the K computer. We investigate the root causes of such performance problems through MDTEST benchmark runs and confirm the performance improvement by server-side quality-of-service management in service thread assignment for incoming client requests on a meta-data server.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"SPRINGER INTERNATIONAL PUBLISHING AG","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/978-3-030-02465-9_3"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1611-3349","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yuichi Tsujita","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Yoshitaka Furutani","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hajime Hida","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Keiji Yamamoto","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Atsuya Uno","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Fumichika Sueyasu","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"I/O Interference Alleviation on Parallel File Systems Using Server-Side QoS-Based Load-Balancing","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"I/O Interference Alleviation on Parallel File Systems Using Server-Side QoS-Based Load-Balancing","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"7","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-09-20"},"publish_date":"2023-09-20","publish_status":"0","recid":"6368","relation_version_is_last":true,"title":["I/O Interference Alleviation on Parallel File Systems Using Server-Side QoS-Based Load-Balancing"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2023-09-20T08:09:26.485762+00:00"}
