The code was parallelized using the Message Passing Interface and OpenMP with two-directional domain decomposition and optimized on the K computer. High resolution DNSs with up to 122883 grid points were performed on the K computer using the code. Efficiencies of 3.84%, 3.14%, and 2.24% peak performance were obtained in double precision DNSs with 61443, 81923, and 122883 grid points, respectively. In addition, a two-path alias-free procedure is proposed and clarified its effectiveness for some number of parallel processes.","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":"10.1007/978-3-030-22747-0_44"}}]},"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":"Yokokawa, Mitsuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Morishita, Koji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ishihara, Takashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Uno, Atsuya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kaneda, Yukio","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Performance of a Two-Path Aliasing Free Calculation of a Spectral DNS Code","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of a Two-Path Aliasing Free Calculation of a Spectral DNS Code","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":"6369","relation_version_is_last":true,"title":["Performance of a Two-Path Aliasing Free Calculation of a Spectral DNS Code"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2023-09-20T08:09:33.928429+00:00"}
