In the FDM, we can extract the peak performance of the supercomputer efficiently because a scheme based on the FDM is suitable for the hardware of the supercomputer. On the other hand, the FEM, which can treat arbitrary shapes and boundary conditions, is not suitable for the vector calculating machine because the finite-element subdivision is often irregular. In the present study, we develop a preconditioner suitable for a vector calculating machine in the ICCG method. The usual preconditioner by means of Incomplete Cholesky Decomposition is not suitable for a vector calculating machine because many recursions occur in a preconditioning procedure. Then, we use a finite element which has another node at a center of gravity in the usual serendipity element. Using this element, we could reduce the number of recursions in the precondition.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_text":"https://hyokadb02.jimu.kyutech.ac.jp/html/14_ja.html","subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/14_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人日本シミュレーション学会"}]},"item_21_relation_66":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110003891195","subitem_relation_type_select":"NAID"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本シミュレーション学会"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00329524","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9947","subitem_source_identifier_type":"PISSN"}]},"item_21_text_28":{"attribute_name":"論文ID（連携）","attribute_value_mlt":[{"subitem_text_value":"10011418"}]},"item_21_text_36":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学工学部原子力工学科"},{"subitem_text_value":"東京大学工学部原子力工学科"}]},"item_21_text_63":{"attribute_name":"連携ID","attribute_value_mlt":[{"subitem_text_value":"107"}]},"item_21_version_type_58":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"矢川,  元基","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"19664","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Akahoshi, Yasuhiro","creatorNameLang":"en"},{"creatorName":"赤星, 保浩","creatorNameLang":"ja"},{"creatorName":"アカホシ, ヤスヒロ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Akahoshi","familyNameLang":"en"},{"familyName":"赤星","familyNameLang":"ja"},{"familyName":"アカホシ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yasuhiro","givenNameLang":"en"},{"givenName":"保浩","givenNameLang":"ja"},{"givenName":"ヤスヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"5459","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60222519","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000060222519"},{"nameIdentifier":"7003586539","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=7003586539"},{"nameIdentifier":"14","nameIdentifierScheme":"九工大研究者情報","nameIdentifierURI":"https://hyokadb02.jimu.kyutech.ac.jp/html/14_ja.html"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-06"}],"displaytype":"detail","filename":"Sim8_49.pdf","filesize":[{"value":"636.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Sim8_49.pdf","url":"https://kyutech.repo.nii.ac.jp/record/4897/files/Sim8_49.pdf"},"version_id":"d5224318-92f8-4548-843a-805b8cfeb65e"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"不完全コレスキー分解による前処理の高速化 : ベクトル計算機向き手法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"不完全コレスキー分解による前処理の高速化 : ベクトル計算機向き手法の開発","subitem_title_language":"ja"}]},"item_type_id":"21","owner":"3","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-04-06"},"publish_date":"2017-04-06","publish_status":"0","recid":"4897","relation_version_is_last":true,"title":["不完全コレスキー分解による前処理の高速化 : ベクトル計算機向き手法の開発"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-10-25T08:21:05.807658+00:00"}
