Using a new iso-QoS evaluation methodology, we scale server resources to meet QoS targets and directly rank the servers in terms of their energy-efficiency and by extension cost of ownership. Our metric and method are platform-independent and enable fair comparison of datacenter compute servers with significant architectural diversity, including micro-servers. We deploy our metric and methodology to compare three servers running financial option pricing workloads on real-life market data. We find that server ranking is sensitive to data inputs and desired QoS level and that although scale-out micro-servers can be up to two times more energy-efficient than conventional heavyweight servers for the same target QoS, they are still six times less energy efficient than high-performance computational accelerators. <\/jats:p>","DOI":"10.1142\/s0129626415410042","type":"journal-article","created":{"date-parts":[[2015,9,28]],"date-time":"2015-09-28T02:41:36Z","timestamp":1443408096000},"page":"1541004","source":"Crossref","is-referenced-by-count":2,"title":["Iso-Quality of Service: Fairly Ranking Servers for Real-Time Data Analytics"],"prefix":"10.1142","volume":"25","author":[{"given":"Giorgis","family":"Georgakoudis","sequence":"first","affiliation":[{"name":"School of Electronics, Electrical Engineering and Computer Science, Queen\u2019s University Belfast, Northern Ireland BT7 1NN, United Kingdom"}]},{"given":"Charles","family":"Gillan","sequence":"additional","affiliation":[{"name":"The Institute for Electronics, Communications and Information Technology, Queen\u2019s University Belfast, Northern Ireland BT7 1NN, United Kingdom"}]},{"given":"Ahmed","family":"Sayed","sequence":"additional","affiliation":[{"name":"School of Electronics, Electrical Engineering and Computer Science, Queen\u2019s University Belfast, Northern Ireland BT7 1NN, United Kingdom"}]},{"given":"Ivor","family":"Spence","sequence":"additional","affiliation":[{"name":"The Institute for Electronics, Communications and Information Technology, Queen\u2019s University Belfast, Northern Ireland BT7 1NN, United Kingdom"}]},{"given":"Richard","family":"Faloon","sequence":"additional","affiliation":[{"name":"Neueda Consulting Limited, Glenwood Business Centre, Springbank Industrial Estate Belfast, Northern Ireland BT17 0QL, United Kingdom"}]},{"given":"Dimitrios S.","family":"Nikolopoulos","sequence":"additional","affiliation":[{"name":"School of Electronics, Electrical Engineering and Computer Science, Queen\u2019s University Belfast, Northern Ireland BT7 1NN, United Kingdom"}]}],"member":"219","published-online":{"date-parts":[[2015,9,27]]},"reference":[{"key":"p_2","first-page":"29","author":"Gillan CJ","year":"2014","journal-title":"USA"},{"key":"p_3","first-page":"181","author":"Foster I RA, V S","year":"2000","journal-title":"Proceedings of the Eighth International Workshop on Quality of Service"},{"key":"p_4","first-page":"634","year":"2005","journal-title":"Proceedings of the International Conference on Dependable Systems and Networks"},{"key":"p_5","first-page":"105","author":"Liu X","year":"2010","journal-title":"USA"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1007\/s11227-010-0504-1"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1109\/88.242438"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1007\/s11227-013-1057-x"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1177\/1094342011414749"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1145\/2556583"},{"key":"p_15","first-page":"1","volume":"208","author":"Morales VM","year":"2014","journal-title":"Belgium"},{"key":"p_16","first-page":"1","author":"Gillan C","year":"2014","journal-title":"UK"}],"container-title":["Parallel Processing Letters"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0129626415410042","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T12:34:32Z","timestamp":1565181272000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0129626415410042"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,9]]},"references-count":11,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2015,9,27]]},"published-print":{"date-parts":[[2015,9]]}},"alternative-id":["10.1142\/S0129626415410042"],"URL":"https:\/\/doi.org\/10.1142\/s0129626415410042","relation":{},"ISSN":["0129-6264","1793-642X"],"issn-type":[{"value":"0129-6264","type":"print"},{"value":"1793-642X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,9]]}}}
