Gate Arrays (FPGA) を採用し，MOST に基づく津波シミュレータを開発する．浅水方程式ソルパをストリーム計算要素 (Stream Processing Element, SPE) として設計し，その HDL コードの生成には高位合成コンパイラ SPGen を用いる．28nm 世代の ALTERA Stratix V FPGA 上に単一の SPE のみ，または 2 つの SPE

of Shallow Water Equations (SWEs), which is used for forecasting tsunami. Tsunami Simulation using MOST is usually run with a supercomputer, however it is difficult to take a rapid responce to disaster with such a large-scale computing system. One of the solutions to this problem is development of a compact system with custom computing machines. In this paper, we use Field-Programmable Gate Arrays (FPGAs) as a platform to build a custom computing machine of Tsunami simulation based on MOST. We design Stream Processing Element (SPE) as a hardware SWEs solver by using our stream-computation hardware compiler, called SPGen. We implement hardware with a single SPE or two cascaded SPEs on 28 nm ALTERA Stratix V FPGA, which achieves 51.8 GFlop/s or 103.7 GFlop/s, bringing the performance per power of 1.71 GFlop/sW or 2.91 GFlop/sW, respectively.","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":"2016-01-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2016-ARC-218"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:22:36.638035+00:00","updated":"2025-01-20T12:55:13.025166+00:00","id":147505}
