1 つの母集団とみなしてサンプリングを行う手法では，イテレーション間のコスト変動が大きい場合に，サンプル数の増加や推定誤差が大きくなってしまうという問題があった．本稿では，この問題を K 平均法によるクラスタリングを用いてサンプル数，サンプル位置の特定を行うことで解決を試みる．動画圧縮アプリケーションの MPEG2 エンコーダを実サーバー上で動作させて得た計測結果を元に検証したところ，クラスタリングをすることによって，クラスタリングを行わない場合と比較して最大で 11.4 倍の速度向上が見込まれることが分かった．推定誤差については，検証した全ての条件で目標とする誤差の範囲に収められる見込みとなった．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"This paper examines an acceleration technique of many-core architecture simulator by statistical sampling on loop blocks in a program. The authors' previous work has a problem that the number of samples increases and estimation error becomes greater, since the previous work assumes that the cost of iterations is not varied so much. This paper proposes using clustering by K-means for making decision about sampling in order to solve the problem. MPEG2 encoder, that is video compression application, is used for examination. The preliminary evaluation shows the proposed technique achieves 11.4 times speed up compared with the previous work. In addition, the estimation error becomes under the target range.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-03-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2012-ARC-199"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":81323,"links":{}}
