コンピューティング向けプログラムモデルの一つとして,その記述の容易さから OpenACC が注目されている.しかし,OpenACC には,計算処理を分割し CPU-GPU 間で負荷分散を行うための仕組みが提供されておらず,GPU による計算中に CPU の計算資源が無駄になってしまう問題がある.そこで本研究では,プログラマが指示文を用いて CPU-GPU 間の負荷分散を容易に記述できるよう,OpenMP/OpenACC ハイブリッド並列化のためのコード変換フレームワークを提案する.本研究ではハイブリッド並列化の対象を C 言語の for ループとし,CPU と GPU それぞれで実行するタスクの量をプログラマが指定するための OpenACC 拡張指示文を導入する.上記の指示文の内容に基づき,提案フレームワークでは OpenMP と OpenACC でハイブリッド並列化されたコードへの自動変換を目指す.本稿では,提案フレームワークにおけるハイブリッド並列化の有効性を確認するため,行列積と 2 種の N 体問題に対し OpenMP と OpenACC によるハイブリッド並列化コードに対して評価を行った.その結果,OpenACC を用いた GPU のみによる計算に対し,最大で 1.57 倍の高速化を確認した.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング(HPC)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-11-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2022-HPC-187"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":222651,"links":{}}
