Meanwhile, the amount of per-core memory resources seems to be limited. Partitioned Virtual Address Space (PVAS) is a new task model, which enables efficient parallel processing in such many-core environments. The PVAS task model allows multiple processes to run in the same address space, which means that processes running on the PVAS task model can conduct intra-node communication without incurring extra costs when crossing address space boundaries. In this paper, the PVAS task models is applied to Message Passing Interface (MPI), and many-core friendly MPI intra-node communication, which can conduct fast communication with small memory footprint, is proposed. The benchmark results show that the MPI intra-node communication proposed in this paper improves MPI application performance by up to 18%. Moreover, the memory footprint for MPI intra-node communication is decreased by up to 264MB.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"54","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":"36","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"8"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T19:01:36.558376+00:00","created":"2025-01-19T00:19:48.228058+00:00","links":{},"id":142339}
