For achieving high performance computing on large scale distributed memory parallel computers such as the Earth Simulator, an optimization of commu-nication processings in user applications is required, and the optimization needs an evaluation for performance of communication methods. On the Earth Simulator, Message Passing Interface (MPI) is supported as the communication method. We have evaluated performance of the MPI-1/MPI-2 functions on the Earth Simulator in detail using MBL which was developed for the measurements of MPI performance on various parallel computers. The results show that the maximum throughputs of ping-pong communication using MPI Send are 14.8 GB/s within a node and 11.8 GB/s between two nodes. Latencies of MPI Send and MPI Put are 5.58 microseconds and 6.36 microseconds, respectively. On the condition that run one MPI-process on one node and use 512 nodes, latencies of MPI Barrier and MPI Win fence are 3.25 microseconds and 223.75 microseconds, respectively. We found out that the MPI on the Earth Simulator has excellent performance.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"34","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌ハイパフォーマンスコンピューティングシステム(HPS) "}],"bibliographicPageStart":"24","bibliographicIssueDates":{"bibliographicIssueDate":"2003-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG01(HPS6)","bibliographicVolumeNumber":"44"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
