Our experience shows that the major difficulties to adapt the code to the MPI\/SMPSs instance of this programming model are due to the usage of the conventional column-major layout of matrices in numerical libraries. On the other hand, the experimental results show a considerable increase in the performance and scalability of our solution when compared with the standard options based on the use of a pure MPI approach or a hybrid one that combines MPI\/multi-threaded BLAS.<\/jats:p>","DOI":"10.3233\/978-1-61499-041-3-657","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:30:51Z","timestamp":1739979051000},"source":"Crossref","is-referenced-by-count":0,"title":["Symmetric Rank-k Update on Clusters of Multicore Processors with SMPSs"],"prefix":"10.3233","author":[{"family":"Badia Rosa M.","sequence":"additional","affiliation":[]},{"family":"Labarta Jesus","sequence":"additional","affiliation":[]},{"family":"Marjanovic Vladimir","sequence":"additional","affiliation":[]},{"family":"Mart&iacute;n Alberto F.","sequence":"additional","affiliation":[]},{"family":"Mayo Rafael","sequence":"additional","affiliation":[]},{"family":"Quintana-Ort&iacute; Enrique S.","sequence":"additional","affiliation":[]},{"family":"Reyes Ruym&aacute;n","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Advances in Parallel Computing","Applications, Tools and Techniques on the Road to Exascale Computing"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:55:18Z","timestamp":1739980518000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0927-5452&volume=22&spage=657"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-041-3-657","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2012]]}}}
