(PCI-Express Adaptive Communication Hub ver3) とはスーパーコンピュータにて使用される PCIe の通信を行うスイッチングハブである．本来 PCIe はコンピュータ内部にて完結して使われる通信規格であるが，PEACH3 を用いることで内部だけでなく外部のノードに延長し，通信を行うことが可能になる．そのため，GPU (Graphics Processing Unit) クラスタ等で従来問題となっていたノード間通信を低レイテンシ，高バンド幅で行うことが出来，性能向上につながる．宇宙分野にて広く研究がなされている N 体シミュレーションのツリー法を複数の GPU を用いて並列に実行するためには各 GPU のプロセス間の通信が多く行われてしまう．そこで PEACH3 を用いて実装を行うことにより，ノードを跨いだ GPU 間を直接 PCIe にて通信することができるようになる．ツリー法の中でも，Locally Essential Tree (LET) を作成する演算に着目し，この処理をスイッチングハブである PEACH3 内部で実行することで更なる性能向上を図る．我々は本研究のようなスイッチングハブに演算機構を取り付け，高速化するシステムをアクセラレータインスイッチと呼ぶ．PEACH3 ヘ演算回路を取り付けた結果，PEACH3 のリソースを 40% に抑え，その上で LET 作成と通信時間に関して最大で約 5.3 倍の高速化を達成し，アクセラレータインスイッチの有用性を示すことができた．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-03-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"63","bibliographicVolumeNumber":"2017-EMB-44"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T05:15:58.684916+00:00","created":"2025-01-19T00:47:30.642217+00:00","id":178138}
