MPI (Message Passing Interface) 通信の通信時間，実行された MPI 関数，通信を行う計算ノードを把握することは，並列計算プログラムをデバッグ，チューニングする上で重要である．しかし，MPI 通信で発生したイベントの把握に有用な INAM，MPE，TAU 等の既存ツールは，利用者によるプログラム修正を必要とする点 (利用者に対する侵襲性) と，計算ノードの CPU，メモリ等の計算資源に負荷を与える点 (計算ノード資源に対する侵襲性) に問題がある．一方で，計算ノード上の CPU で行われるネットワーク処理をオフロード可能なデバイスとして BlueField-2 DPU (Data Processing Unit) が注目を集め，その利用方法が模索されている．本研究では，利用者と計算ノード資源に対する非侵襲的な MPI 通信ロギングの実現のために，DPU 上でパケットから MPI 通信のログを生成する手法を実現するパケット解析モジュールを提案する．提案モジュールは，パケット複製処理と MPI 通信ログ生成処理の並列化を組み合わせることで，DPU 上でのパケット処理による通信遅延の増加を抑制する．評価では，試作した提案手法が利用者と計算ノード資源に対して非侵襲的に MPI 通信のログを生成できることを確認した．また，提案手法による計算ノード間の通信遅延時間の増加が 100μs 以下であり，オーバヘッドが小さいことを確認した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-05-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2022-OS-155"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":218151,"updated":"2025-01-19T15:15:04.193497+00:00","links":{},"created":"2025-01-19T01:18:34.200163+00:00"}
