which uses frequent neighboring communications as well as reductions in linear solvers. For this reason, in the development of supercomputer Fugaku, it is one of the target applications for codesign, where hardware developers, system software developers, and application software developers work in close collaboration with each other. In this talk, we report some outcomes from the codesign activities: acceleration of communication we achieved in iterative linear solver for the lattice QCD application. By using the low latency interface uTofu , we realized a smaller overhead for neighboring communications than that with MPI persistent communications, and a refined assignment of the communication resources. We also realized acceleration of reduction with small numbers of elements for inner products by using the Tofu barrier feature.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","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":"2020-12-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicVolumeNumber":"2020-HPC-177"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:10:15.130146+00:00","id":208886,"links":{}}
