This architecture\u2014algorithm performance gap will get even wider with the increase in computing power being driven by a rapid escalation in the number of cores incorporated into a single chip rather than increases in the clock rate. In order to improve the effectiveness of peta and exascale systems we need to have a paradigm shift where architectures and algorithms are co-designed. <\/jats:p>","DOI":"10.1177\/1094342009347766","type":"journal-article","created":{"date-parts":[[2009,9,17]],"date-time":"2009-09-17T00:45:24Z","timestamp":1253148324000},"page":"401-402","source":"Crossref","is-referenced-by-count":16,"title":["IESP Exascale Challenge: Co-Design of Architectures and Algorithms"],"prefix":"10.1177","volume":"23","author":[{"given":"Al","family":"Geist","sequence":"first","affiliation":[{"name":"OAK RIDGE NATIONAL LABORATORY, PO BOX 2008, TN, 37831-6367\rUSA,"}]},{"given":"Sudip","family":"Dosanjh","sequence":"additional","affiliation":[{"name":"SANDIA NATIONAL LABORATORIES, 1515 EUBANK BLVD SE, ALBUQUERQUE,\rNM 87123, USA"}]}],"member":"179","published-online":{"date-parts":[[2009,9,16]]},"container-title":["The International Journal of High Performance Computing Applications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1094342009347766","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1094342009347766","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,3]],"date-time":"2025-03-03T22:08:11Z","timestamp":1741039691000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1094342009347766"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,16]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2009,11]]}},"alternative-id":["10.1177\/1094342009347766"],"URL":"https:\/\/doi.org\/10.1177\/1094342009347766","relation":{},"ISSN":["1094-3420","1741-2846"],"issn-type":[{"value":"1094-3420","type":"print"},{"value":"1741-2846","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,16]]}}}
