during dot product operations in Krylov subspace methods, such as Conjugate Gradient Method (CG), on massively parallel supercomputers. Pipelined CG developed by Ghysels et al. applies recurrence relations on original CG algorithm. Although sequence of operations is different from that of original CG, algorithm of the pipelined CG is kept as that of original one. It is widely known that the pipelined CG with asynchronous collective communication supported in MPI-3 standard can hide overhead of collective communications by overlapping communications and computations. In the present work, performance evaluations of 3D finite-element applications for solid mechanics with pipelined CG on Reedbush-U (ITC, University of Tokyo), and Oakforest-PACS (JCAHPC) are demonstrated.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"9","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-12-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2016-HPC-157"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":176373,"updated":"2025-01-20T05:53:25.808380+00:00","links":{},"created":"2025-01-19T00:46:01.493286+00:00"}
