While two of them use libraries such as MPI, OpenMP, or Threading Building Blocks (TBB) directly, the other two implementations use algorithmic skeletons of the M&amp;uuml;nster Skeleton Library Muesli to hide the parallelism. We compare the implementations w.r.t. runtime, efficiency, and programming style and show the resulting benchmarks which have been conducted on a multi-processor, multi-core cluster computer.<\/jats:p>","DOI":"10.3233\/978-1-60750-530-3-169","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":["Parallelizing the LM OSEM Image Reconstruction on Multi-Core Clusters"],"prefix":"10.3233","author":[{"family":"Ciechanowicz Philipp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Kegel Philipp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Schellmann Maraike","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Gorlatch Sergei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Kuchen Herbert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Advances in Parallel Computing","Parallel Computing: From Multicores and GPU's to Petascale"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:48:30Z","timestamp":1739980110000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0927-5452&volume=19&spage=169"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-530-3-169","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2010]]}}}
