New SPECviewperf 7.1 Benchmark Gets Closer to Real-World Application Performance.Business Editors/High-Tech Writers WARRENTON, Va.--(BUSINESS WIRE)--March 19, 2003 SPEC/GPC's OpenGL Performance Characterization (SPECopc) project group today released SPECviewperf 7.1, a new version of its performance evaluation Performance evaluation The assessment of a manager's results, which involves, first, determining whether the money manager added value by outperforming the established benchmark (performance measurement) and, second, determining how the money manager achieved the calculated return software that includes dynamic data changes to better reflect real-world application behavior. SPECviewperf 7.1 can be downloaded on SPEC's GPC (1) A PC that uses the Linux-based gOS operating system. See gOS. (2) (GPC Group) Originally the Graphics Performance Characterization committee of the NCGA, the GPC Group is now part of Standard Performance Evaluation Corporation (SPEC) and oversees the following News web site (www.spec.org/gpc). Testing results using the new benchmark are also available on the site. SPECviewperf 7.1 introduces new data changes to discourage optimizations that benefit the benchmark, but might not improve real-world application performance. The benchmark inserts a small amount of variation at regular intervals within its application-based test files, called viewsets. This ensures that the test system examines and processes each frame individually, as it would in typical real-world applications. Also new to the benchmark is a second frame counter that moves around within the frame. This provides visual verification of whether frame changes are being rendered. All SPECviewperf viewsets have been updated to include these changes, except for ugs-03, which is based on a display-list application whose data by definition is static. The ugs-03 viewset has been upgraded with new subtests that measure performance for both aliased See alias and aliasing. and anti-aliased lines. The frame variation upgrades in SPECviewperf build on the move last year to generate viewsets from actual application traces, which brought the benchmark tests closer to reflecting real-world performance. "SPECviewperf 7.1 furthers our goal to measure performance in a way that corresponds as closely as possible to what everyday users experience with their applications," says Ian Williams Ian Williams (born 1970 in Johnstown, Pennsylvania) is an American rock guitarist. Williams is most well known for his unique approach to finger tapping on guitar and utilizing two Akai Headrush guitar pedals. , SPECopc chair. "We intend to evolve SPECviewperf faster than ever before to reflect current application behavior." As a result of the major revisions, results reported under SPECviewperf 7.1 cannot be compared with those from SPECviewperf 7.0 or earlier versions of the benchmark. About SPECviewperf SPECviewperf measures the 3D rendering performance of systems running under the OpenGL application programming interface (API (Application Programming Interface) A language and message format used by an application program to communicate with the operating system or some other control program such as a database management system (DBMS) or communications protocol. ). The benchmark's viewsets represent a similar mix of graphics rendering and manipulation found in actual applications. There are currently six viewsets based on popular applications for digital content creation The development of newsworthy, educational and entertainment material for distribution over the Internet or other electronic media.
