消費電力，DRAM 消費電力に制限をかけた場合の惑星磁気圏 MHD シミュレーションコードがどのような消費電力特性を持つかを調べた．その結果，差分計算を行い計算負荷が高い箇所では CPU 消費電力制限の影響を強く受け，境界値設定などデータのやりとりが多い箇所では DRAM 消費電力制限の影響を受けやすいことが明らかになった．さらに CPU，DRAM の消費電力を同時に制限することで，MHD シミュレーションコードがどのような実効性能の変化を見せるかを調べ，コードにとって最適な CPU-DRAM

generation computer system, the power consumption becomes the important issue. On the other hand, the power consumption character of application program is not so considered now. In this study we examine the power character of our Magnetohydrodynamic (MHD) simulation code for the global magnetosphere to evaluate the power consumption behavior of the simulation code under the CPU and DRAM power capping on the parallel computer system. As a result, it is confirmed that there are different power consumption parts in the MHD simulation code, which the execution performance decreases or does not change under the CPU power capping. This indicates the capability of performance optimization with the power capping.","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":"2014-09-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2014-HPC-146"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":103170,"updated":"2025-01-21T10:30:42.552991+00:00","links":{},"created":"2025-01-18T23:48:14.719539+00:00"}
