The underlying explicit time-advance scheme is based on a Lagrange+remap discretization. The algorithm consists in nine elementary kernels that exhibit, for most of them, a stencil update pattern. Using the Execution Cache Memory (ECM) model &amp;mdash; a refinement of the Roofline model &amp;mdash;, we devise a high fidelity performance model, allowing us to finely understand and overcome bottlenecks of the algorithm and accurately predict global code performance.<\/jats:p>","DOI":"10.3233\/978-1-61499-621-7-449","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:30:51Z","timestamp":1739979051000},"source":"Crossref","is-referenced-by-count":1,"title":["Performance modeling of a compressible hydrodynamics solver on multicore CPUs"],"prefix":"10.3233","author":[{"family":"Poncet Rapha&euml;l","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Peybernes Mathieu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Gasc Thibault","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"De Vuyst Florian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Advances in Parallel Computing","Parallel Computing: On the Road to Exascale"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:41:08Z","timestamp":1739979668000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-620-0&spage=449&doi=10.3233\/978-1-61499-621-7-449"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-621-7-449","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2016]]}}}
