The operating system is an example of a common code pattern that is constantly executing on every processor. It is therefore a prime candidate for core customization. Recent work has begun to explore this possibility, where some fraction of system calls and other OS functionality is off-loaded to a separate special-purpose core. Studies have shown that this can improve overall system performance and power consumption. However, our explorations in this arena reveal that the primary benefits of off-loading can be captured with alternative mechanisms that eliminate the negative effects of off-loading. This position paper articulates this alternative mechanism with initial results that demonstrate promise.<\/jats:p>","DOI":"10.1145\/1531793.1531812","type":"journal-article","created":{"date-parts":[[2009,4,28]],"date-time":"2009-04-28T14:58:07Z","timestamp":1240930687000},"page":"104-105","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["OS execution on multi-cores"],"prefix":"10.1145","volume":"43","author":[{"given":"David","family":"Nellans","sequence":"first","affiliation":[{"name":"University of Utah, Salt Lake City, Utah"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajeev","family":"Balasubramonian","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, Utah"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik","family":"Brunvand","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, Utah"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2009,4,21]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/48012.48037"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1375527.1375541"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1168857.1168893"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/168619.168629"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.micpro.2005.12.001"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/MM.2008.47"},{"key":"e_1_2_1_7_1","volume-title":"IBM Annual Thomas J.
