In the algorithms of these methods, inner linear systems need to be solved and its calculation time becomes the most time-consuming part for large-scale problems. In this paper, we consider applying a contour-integral based method to a large dense problem in conjunction with a block Krylov subspace method as an inner linear solver. Comparison of parallel performance with the contour-integral based method with a direct linear solver and a ScaLAPACK's eigensolver is shown using matrices from a practical application.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Industrial and Applied Mathematics"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.14495/jsiaml.10.77","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2018 Japan Society for Industrial and Applied Mathematics"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-0609","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"二村, 保徳"},{"creatorName":"フタムラ, ヤスノリ","creatorNameLang":"ja-Kana"},{"creatorName":"FUTAMURA, Yasunori","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"今倉, 暁"},{"creatorName":"イマクラ, アキラ","creatorNameLang":"ja-Kana"},{"creatorName":"IMAKURA, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"櫻井, 鉄也"},{"creatorName":"サクライ, テツヤ","creatorNameLang":"ja-Kana"},{"creatorName":"SAKURAI, Tetsuya","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Yano, Takahiro","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":"2019-08-09"}],"displaytype":"detail","filename":"JSIAML_10-77.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JSIAML_10-77","url":"https://tsukuba.repo.nii.ac.jp/record/51893/files/JSIAML_10-77.pdf"},"version_id":"65583905-2d97-4f98-a0f7-08c4fabb8750"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Performance evaluation of the Sakurai-Sugiura method with a block Krylov subspace linear solver for large dense Hermitian-definite generalized eigenvalue problems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance evaluation of the Sakurai-Sugiura method with a block Krylov subspace linear solver for large dense Hermitian-definite generalized eigenvalue problems"}]},"item_type_id":"5","owner":"1","path":["6669","4944","5001","6668"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-08-09"},"publish_date":"2019-08-09","publish_status":"0","recid":"51893","relation_version_is_last":true,"title":["Performance evaluation of the Sakurai-Sugiura method with a block Krylov subspace linear solver for large dense Hermitian-definite generalized eigenvalue problems"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:25:10.282181+00:00"}
