Historically, operating systems have been optimized to time-share a single resource, the CPU. We now have an abundance of cores, but we are still swapping out the application to run other tasks and therefore increasing the application\u2019s time to solution. In addition, with parallel applications the probability of one of the tasks entering a synchronization point late due to one of these interrupts increases with increasing system scale, which further increases the application turn-around time. This paper reviews measures that can be taken to reduce application interruption using only compile and run time configurations in a recent unmodified Linux kernel. Although these measures have been available for some time, to the best of the authors\u2019 knowledge, they have never been implemented in a high-performance computing context. We then introduce our invasive method, where we remove the involuntary preemption induced by task scheduling. Our experiments show that parallel applications benefit from these modifications even at relatively small scales. At the modest scale of our testbed, we see a 1.91% improvement in a bulk-synchronous-parallel application that should project into higher benefits at extreme scales.<\/jats:p>","DOI":"10.1177\/1094342013477892","type":"journal-article","created":{"date-parts":[[2013,3,2]],"date-time":"2013-03-02T04:19:24Z","timestamp":1362197964000},"page":"136-146","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Understanding and isolating the noise in the Linux kernel"],"prefix":"10.1177","volume":"27","author":[{"given":"Hakan","family":"Akkan","sequence":"first","affiliation":[{"name":"New Mexico Consortium, Los Alamos, NM, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Lang","sequence":"additional","affiliation":[{"name":"Los Alamos National Laboratory, Los Alamos, NM, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorie","family":"Liebrock","sequence":"additional","affiliation":[{"name":"New Mexico Institute of Mining and Technology, Socorro, NM, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,2,28]]},"reference":[{"key":"bibr1-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1145\/1629575.1629579"},{"key":"bibr2-1094342013477892","unstructured":"Ben-Yossef G (2012) Reduce cross-CPU IPI interference. http:\/\/lkml.org\/lkml\/2012\/2\/9\/59."},{"key":"bibr3-1094342013477892","author":"Ferreira KB","year":"2008","journal-title":"Proceedings of the 2008 ACM\/IEEE Conference on Supercomputing"},{"key":"bibr4-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1109\/SC.2010.12"},{"key":"bibr5-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1145\/1048935.1050161"},{"key":"bibr6-1094342013477892","author":"Kelly SM","year":"2006","journal-title":"Cray Users Group Conference"},{"key":"bibr7-1094342013477892","author":"Liu R","year":"2009","journal-title":"Proceedings of the First USENIX Conference on Hot Topics in Parallelism (HotPar\u201909)"},{"key":"bibr8-1094342013477892","unstructured":"Meuer H, Strohmaier E, Dongarra J, Simon H (2009) Top500 report for November 2011. http:\/\/i.top500.org\/stats."},{"key":"bibr9-1094342013477892","unstructured":"Minnich R (2011) NIX 64-bit kernel is available. http:\/\/9fans.net\/archive\/2011\/09\/145."},{"key":"bibr10-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1109\/IPDPS.2011.84"},{"key":"bibr11-1094342013477892","author":"Oral HS","year":"2010","journal-title":"Cray Users Group Conference"},{"key":"bibr12-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1145\/1048935.1050204"},{"key":"bibr13-1094342013477892","author":"Sancho JC","year":"2010","journal-title":"Proceedings of the 16th International Euro-Par Conference on Parallel Processing"},{"key":"bibr14-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1142\/S0129626410000284"},{"key":"bibr15-1094342013477892","doi-asserted-by":"publisher","DOI":"10.1145\/1088149.1088190"},{"key":"bibr16-1094342013477892","unstructured":"Weisbecker F (2012) Nohz cpusets. http:\/\/lkml.org\/lkml\/2012\/4\/30\/380."}],"container-title":["The International Journal of High Performance Computing Applications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1094342013477892","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1094342013477892","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1094342013477892","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T08:19:10Z","timestamp":1777450750000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1094342013477892"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,2,28]]},"references-count":16,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2013,5]]}},"alternative-id":["10.1177\/1094342013477892"],"URL":"https:\/\/doi.org\/10.1177\/1094342013477892","relation":{},"ISSN":["1094-3420","1741-2846"],"issn-type":[{"value":"1094-3420","type":"print"},{"value":"1741-2846","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,2,28]]}}}
