の様な大規模並列型スパコンで効率よく動作する粒子法プログラムの開発は容易ではなく，多くの研究者はソフトウェアの開発に多大な時間と労力を割いている．そこで，本研究では，「京」 の様な大規模並列型スパコンで効率よく動作する粒子法シミュレーションプログラムをユーザーが容易に開発できるフレームワーク (FDPS: Framework for DevelopingParticle Simulator) を開発した．粒子法の大規模並列プログラムが複雑になるのは，計算領域分割やその領域に合わせた粒子の再配分，また効率的な相互作用のために必要な粒子のツリー構造での管理等が必要なためである．FDPS はこの部分を担当する．そのため，ユーザーは並列化を意識することなくプログラムの開発を行うことができる．我々は，実際に FDPS を使ったいくつかのプログラムの開発も行い，「京」 などのスパコンで実行した．その結果，プログラムが数百行で書け，また非常に高い実行効率が出る事を確認した．","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":"2015-07-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2015-HPC-150"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"links":{},"id":144607,"updated":"2025-01-20T18:44:44.124739+00:00"}
