The report presents a concise summary of code performance characteristics using 28 performance attributes grouped into four categories: operations and instruc tions, scalar to vector load balance, memory utilization, and input\/output utilization. Demonstrated applications of this performance metric include code performance analysis in a case study, workload analysis for a 24- code sample, and performance comparison of CRAY X-MP and Y-MP processors. The analysis of the case study shows that a precise performance assessment was possible using this metric without the necessity of source code analysis. Measurements with the 24-code sample established realistic performance ranges in the metric and were also used to compare performance of CRAY X-MP and Y-MP models. Although the clock pe riod on the Y-MP was reduced by 29% relative to the X-MP, increases of 52% were observed in instruction fetch rates and vector MFLOPS, with a corresponding rise of 39% in computational intensity. <\/jats:p>","DOI":"10.1177\/109434209300700403","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T01:17:47Z","timestamp":1173057467000},"page":"304-336","source":"Crossref","is-referenced-by-count":0,"title":["Performance Attributes for Code and Workload Analysis On Cray X-Mp and Y-Mp Systems"],"prefix":"10.1177","volume":"7","author":[{"given":"George","family":"Delic","sequence":"first","affiliation":[{"name":"MARTIN MARIETTA TECHNICAL SERVICES, INC.
