抄録

私達は，通常スキルプログラマーが少コアCPU向けに記述したソフトウェアコードを，配置環境に応じて，自動で変換，設定等して，高性能に処理する環境適応ソフトウェアを提案している．本稿は，ブロック行列計算，自明並列処理等の処理の計算タイプに応じた，メニーコアCPUへの自動オフロードを対象とする．オフロードしたい既存のアプリケーションをパターンマッチングで抽象構文木を用いて意味的に分析し，置換可能なOpenMPがある計算タイプか把握する．OpenMPが見つかった場合は，そのOpenMPに置換し性能向上を確認する．提案方式で自動オフロードできることを，AMD Ryzen Threadripper 3995WXの64コアCPUを用いて確認する．
