The technique of user-level communication to achieve high communication performance is widely used by parallel applications, and processes are spinning-wait for the incoming messages. This spinning loop in the absence of incoming messages is simply wasting energy and thus increase the power consumption of a parallel computer. In this paper, it is proposed to decrease the power used for the waiting loop by applying the well-known two-phase synchronization technique. This technique is implemented in two ways; 1) combination of spin-loop and blocking system call, and 2) combination of spin-loop and using the x86 monitor/mwait synchronization instructions which put computational core into a low-power mode. Unlike the techniques using the DVFS function of CPU, our proposed technique does not sacrifice application performance but can save energy. Evaluations show that more than 3% total system power can be saved with the FT application of NAS parallel benchmarks.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-11-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2011-ARC-197"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":79272,"updated":"2025-01-21T20:17:59.785516+00:00","links":{},"created":"2025-01-18T23:34:02.924483+00:00"}
