The compiler is able to use this information to make optimisation decisions that improve the way the code is laid out in memory or determine which routines are inlined, and hence improve the performance of the application.<\/jats:p>\n          <jats:p>The use of profile feedback requires the code to be compiled twice. The first time the compiler generates an instrumented version of the application. This instrumented version is then run on one or more 'representative' training workloads to gather profile data. This profile data contains information such as how many times each routine is executed and how frequently each branch is taken. The second pass through the compiler uses this information to make more enlighted optimisation decisions.<\/jats:p>\n          <jats:p>The quality of the training data impacts the ability of the compiler to do the best job that it can. This paper discusses a method of assessing the similarity of the training workload to the reference workload, and applies this methodology to evaluate the training workloads in the SPEC CPU2006 benchmark suite.<\/jats:p>","DOI":"10.1145\/1241601.1241624","type":"journal-article","created":{"date-parts":[[2007,6,6]],"date-time":"2007-06-06T14:37:16Z","timestamp":1181140636000},"page":"122-129","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Evaluating the correspondence between training and reference workloads in SPEC CPU2006"],"prefix":"10.1145","volume":"35","author":[{"given":"Darryl","family":"Gove","sequence":"first","affiliation":[{"name":"Sun Microsystems Inc., Sunnyvale, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lawrence","family":"Spracklen","sequence":"additional","affiliation":[{"name":"Sun Microsystems Inc., Sunnyvale, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2007,3]]},"reference":[{"volume-title":"CPU2006 Benchmark Suite,\" http:\/\/www.spec.org\/cpu2006\/.","key":"e_1_2_1_1_1","unstructured":"\"SPEC CPU2006 Benchmark Suite,\" http:\/\/www.spec.org\/cpu2006\/. \"SPEC CPU2006 Benchmark Suite,\" http:\/\/www.spec.org\/cpu2006\/."},{"volume-title":"SPEC Benchmark Workshop http:\/\/www.spec.org\/workshops\/2006\/.","author":"Gove D.","key":"e_1_2_1_2_1","unstructured":"D.
