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"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/6368", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-09-20"}, "publish_date": "2023-09-20", "publish_status": "0", "recid": "6368", "relation": {}, "relation_version_is_last": true, "title": ["I/O Interference Alleviation on Parallel File Systems Using Server-Side QoS-Based Load-Balancing"], "weko_shared_id": -1}
