SW である CReSS (Cloud Resolving Storm Simulator) に対し，機械学習や AI といった，高速演算処理が求められる分野で多く使用されている GPU を用いて並列実装を行った．シングル GPU 環境下における処理速度を評価した結果，CPU 比約 14

essential for building a safe and secure society. For example, disasters caused by local weather conditions, such as local heavy rain and wind, can be prevented by understanding weather conditions and taking measures in advance. On the other hand, the computational cost of high-precision weather prediction processing requires a significant amount of computation time. This is a problem to realize real-time weather prediction. Therefore, to overcome this problem, we developed CReSS, which is a weather prediction simulation SW for massively parallel computers, for GPU clusters. GPU is widely used such as machine learning and AI. We evaluated the processing speed using a single GPU and confirmed the speedup ratio about 14 times that of the CPU.","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・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-07-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"2023-ARC-254"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":227088,"updated":"2025-01-19T12:16:53.721090+00:00","links":{},"created":"2025-01-19T01:26:24.193839+00:00"}
