The analysis reduced the volumi nous hpm data to five dominant factors which were used as performance metrics for applications code ex ecution on the Y-MP. Case studies of Fortran kernels demonstrated that the proposed metrics accurately reflect changes in performance due to source code modifications. Therefore, the factor-analysis model so lution provides a supercomputer performance metric that is both parsimonious and simple to interpret as an alternative to the complexities of hpm-derived perfor mance attributes. Metrics such as these should prove to be of value in code optimization, user training, and characterization of site-specific workloads. <\/jats:p>","DOI":"10.1177\/109434209601000104","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T01:17:47Z","timestamp":1173057467000},"page":"91-113","source":"Crossref","is-referenced-by-count":0,"title":["Factor Analysis of Applications Performance Data for the Cray Y-MP"],"prefix":"10.1177","volume":"10","author":[{"given":"George","family":"Delic","sequence":"first","affiliation":[{"name":"LOCKHEED MARTIN SERVICES GROUP NATIONAL ENVIRONMENTAL\rSUPERCOMPUTING CENTER 135 WASHINGTON AVENUE BAY CITY, MICHIGAN 48708"}]},{"given":"Richard I.","family":"Haller","sequence":"additional","affiliation":[{"name":"DEPARTMENT OF SOCIOLOGY 300 BRICKER HALL 190 NORTH OVAL\rMALL THE OHIO STATE UNIVERSITY COLUMBUS, OHIO 43210"}]}],"member":"179","published-online":{"date-parts":[[1996,3,1]]},"reference":[{"issue":"3","key":"atypb1","first-page":"5","volume":"3","author":"Berry, M.","year":"1989","journal-title":"Internat.
