Simultaneous Multi-Threading 機能を用い、ハードウェアによる高速なスレッドスケジューリングを用い、また、スレッド間の同期機構として Intel 製のプロセッサが提供する monitor/mwait 命令を用いた新しいスレッドライブラリ、Shadow Thread を提案する。高速な同期と低消費電力を両立させるため、同期フラグを

library is proposed to hide the latencies of memory and communication. For this purpose, thread management must be fast enough in the order of sub-micro seconds. In this paper, the thread library, named Shadow Thread, is developed so that it utilizes Simultaneous Multi-Threading mechanism which schedules threads by hardware in a very fast way and utilizes the monitor and mwait instructions supported by some Intel processors. It is shown that the two-phase synchronization technique combining the conventional spin-wait method and the pair of the monitor/mwait instructions can satisfy the requirement of speed and low-power consumption simultaneously. Evaluation shows that a memory copy function using the Shadow Thread library can exhibit better performance up to 20% compared with the normal memcpy function.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-07-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2011-HPC-130"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":75547,"links":{}}
