は我々が開発した高い電力効率と面積効率を持つスーパーコンピュータ向けプロセッサであり，TSMC 7nm プロセス技術を用いて製造されている．PEZY-SC3 は高いスレッドレベル並列性を含むアプリケーションを対象としており，それらにおいて高い効率を実現するために MIMD メニーコアアーキテクチャ，細粒度マルチスレッディング，ノンコヒーレントキャッシュなどの要素を採用している．PEZY-SC3 は MIMD メニーコアアーキテクチャの採用により各コアが独立して動作するため，機能が限定された特殊なテンソルユニットや Wide-SIMD を採用した既存のプロセッサと比較して，高いプログラマビリティを持ちながら高電力効率を実現している．また，PEZY-SC3 の各コアはアウトオブオーダ実行や投機実行のような高コストな技術を一切導入せず，シンプルなパイプラインにより高電力効率と高スループットを両立している．さらに，独自のノンコヒーレントで階層的なキャッシュシステムにより，プログラマビリティを損なうことなくメニーコアにおける高いスケーラビリティを実現している．PEZY-SC3 を搭載したシステムの電力効率は 21.892 GFlops/W であり，スーパーコンピュータの電力効率を測定する Green500（2023 年 6 月）において 39 位となった．本論文ではこの PEZY-SC3 のアーキテクチャの概要と設計について説明する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-07-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2023-ARC-254"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:26:24.076198+00:00","id":227086,"links":{}}
