We evaluate the performance of Big Memory using custom memory benchmarks, NAS Parallel Benchmarks, and the Parallel Ocean Program, at a scale of up to 4,096 nodes. We find that Big Memory successfully resolves the performance issues normally encountered in Blue Gene Linux. For the ocean simulation program, we even find that Linux with Big Memory provides better scalability than does the lightweight compute node kernel designed solely for high-performance applications. Originally intended exclusively for compute node tasks, our new memory subsystem dramatically improves the performance of certain I\/O node applications as well. We demonstrate this performance using the central processor of the LOw Frequency ARray radio telescope as an example. <\/jats:p>","DOI":"10.1177\/1094342010369116","type":"journal-article","created":{"date-parts":[[2010,5,13]],"date-time":"2010-05-13T00:35:23Z","timestamp":1273710923000},"page":"148-160","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Performance and Scalability Evaluation of \u2018Big Memory\u2019 on Blue Gene Linux"],"prefix":"10.1177","volume":"25","author":[{"given":"Kazutomo","family":"Yoshii","sequence":"first","affiliation":[{"name":"Mathematics and Computer Science Division, Argonne National Laboratory, Argonne, IL, USA,"}]},{"given":"Kamil","family":"Iskra","sequence":"additional","affiliation":[{"name":"Mathematics and Computer Science Division, Argonne National Laboratory, Argonne, IL, USA"}]},{"given":"Harish","family":"Naik","sequence":"additional","affiliation":[{"name":"Mathematics and Computer Science Division, Argonne National Laboratory, Argonne, IL, USA"}]},{"given":"Pete","family":"Beckman","sequence":"additional","affiliation":[{"name":"Mathematics and Computer Science Division, Argonne National Laboratory, Argonne, IL, USA, Leadership Computing Facility, Argonne National Laboratory, Argonne, IL, USA"}]},{"given":"P.
