Toward development of a power-efficient and high-performance computing system for 2D tsunami simulation, we conduct feasibility study on stream computation of 1D SWE solver with FPGA.We analyze an original code and design a stream algorithm with techniques of kernel fusion, shift buffering for streamed stencil-data access, and cascading processing elements for a longer pipeline. We implement a deep pipeline with at most 744 stages of 4 SPEs on 28 nm Stratix V FPGA, which achieves 82.4 GFlop\/s at 200 MHz.<\/jats:p>","DOI":"10.1145\/2927964.2927979","type":"journal-article","created":{"date-parts":[[2016,4,25]],"date-time":"2016-04-25T19:51:13Z","timestamp":1461613873000},"page":"82-87","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Stream Computation of Shallow Water Equation Solver for FPGA-based 1D Tsunami Simulation"],"prefix":"10.1145","volume":"43","author":[{"given":"Kentaro","family":"Sano","sequence":"first","affiliation":[{"name":"Tohoku University, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumiya","family":"Kono","sequence":"additional","affiliation":[{"name":"University of Aizu, Ikkimachi Tsuruga, Aizuwakamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naohito","family":"Nakasato","sequence":"additional","affiliation":[{"name":"University of Aizu, Ikkimachi Tsuruga, Aizuwakamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Vazhenin","sequence":"additional","affiliation":[{"name":"University of Aizu, Ikkimachi Tsuruga, Aizuwakamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanislav","family":"Sedukhin","sequence":"additional","affiliation":[{"name":"University of Aizu, Ikkimachi Tsuruga, Aizuwakamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2016,4,22]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Implementation and testing of the method of splitting tsunami (MOST) model.
