To produce machines of such a size, a proprietary cache-coherent interconnect is used to couple standard servers into a large single system. In this work we investigate the ability of such a huge system to run OpenMP applications in an efficient way. Therefore, we use kernel benchmarks to investigate basic performance characteristics of the machine and we present a real world application from the Institute of Combustion Technology at RWTH Aachen University, called TrajSearch, which has been optimized to run efficient on such a large shared memory machine.<\/jats:p>","DOI":"10.3233\/978-1-61499-621-7-83","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":["Evaluating OpenMP Performance on Thousands of Cores on the Numascale Architecture"],"prefix":"10.3233","author":[{"family":"Schmidl Dirk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Vesterkj&aelig;r Atle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"M&uuml;ller Matthias S.","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":"2025-02-19T15:40:19Z","timestamp":1739979619000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-620-0&spage=83&doi=10.3233\/978-1-61499-621-7-83"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-621-7-83","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2016]]}}}
