PGAS 言語 XcalableMP（XMP） の拡張を行う．記述として tasklet 指示文を提案し，ノード内/外におけるタスク間の依存関係の記述による細粒度な同期や，通信と計算のオーバラップによる性能向上を目指す．タスク生成や制御は Argonne National Laboratory（ANL） により開発が進められている軽量スレッドライブラリである Argobots を用いる．現在は，実装対象である Omni XMP Compiler のランタイムのみの実装であるため，コード変換は手動で行う．提案手法の予備評価としてブロックコレスキー分解のコードを対象とし，性能・生産性の評価を行った．比較対象は，MPI+OpenMP による実装と INRIA によって開発が進められている StarPU による実装である．StarPU 実装との比較では一部優位な点が見られたが，MPI+OpenMP 実装との比較では最大で約 15%の性能低下が見られた．生産性の比較では，指示文による記述を採用したことによりベースコードから少ない変更で実装可能なことから，tasklet 指示文による記述の生産性の高さを示した．","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":"2016-08-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"29","bibliographicVolumeNumber":"2016-HPC-155"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:44:22.482675+00:00","id":174143,"links":{}}
