ライブラリに実装した． Trinaryx3 アルゴリズムは，トーラス向けに最適化されており， 「京」 の特長の 1 つである複数 RDMA エンジンを活用することができる．実装を評価した結果，既存のトポロジを考慮していないアルゴリズムと比較して， 5

collective communication on the K computer, which consists of 82,944 computing nodes connected by a 6D direct network, named Tofu interconnect. Existing MPI libraries, however, do not have topology-aware algorithms which perform well on such a direct network. Thus, an Allreduce collective algorithm, named Trinaryx3, is designed and implemented in the MPI library for the K computer. The algorithm is optimized for a torus network and enables utilizing multiple RDMA engines, one of the strengths of the K computer. The evaluation results show the new implementation achieves five times higher bandwidth than existing one.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"162","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"152","bibliographicIssueDates":{"bibliographicIssueDate":"2012-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":86065,"links":{}}
