MPI/GXP focuses on the fact that the computational environment changes from execution to execution, and uses latency and traffic measurements made at run-time to determine how to establish connections and how to map ranks to processes.  In an experiment in which we used 256 processors in 5 clusters, we were able to avoid exceeding the number of sessions that a router can handle by using RTT measurements made at run-time to establish connections mainly with nearby processes instead of with all processes.  In another experiment, the performance of the NAS Parallel Benchmarks increased by 60% to 100% when we replaced a random rank-process mapping with a rank-process mapping that used latency and traffic measurements made at run-time to make communication overhead small.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"30","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"25","bibliographicIssueDates":{"bibliographicIssueDate":"2006-07-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"87(2006-HPC-107)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:58:52.532421+00:00","id":28876,"links":{}}
