paper reports a method of speeding up MPI 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_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"253","bibliographic_titles":[{"bibliographic_title":"先進的計算基盤システムシンポジウム論文集"}],"bibliographicPageStart":"245","bibliographicIssueDates":{"bibliographicIssueDate":"2012-05-09","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2012"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:36:08.337062+00:00","id":82204,"links":{}}
