The SPECopcSM project group made data changes to viewsets running under SPECviewperf 7.1 to discourage optimizations that benefit the benchmark, but might not improve real-world application performance. Since the SPECviewperf source and binaries have been upgraded to support some of these changes, no comparisons should be made between past results and current results for viewsets running under SPECviewperf 7.1. SPECviewperf® is a portable OpenGL performance benchmark program written in C. It was developed by IBM. Later updates and significant contributions were made by SGI, Digital (Compaq, HP), 3Dlabs (Creative Labs) and other SPECopcSM project group members. SPECviewperf provides a vast amount of flexibility in benchmarking OpenGL performance. Currently, the program runs on most implementations of UNIX, Windows XP, Windows 2000, and Linux. SPECviewperf parses command lines and data files, sets the rendering state, and converts data sets to a format that can be traversed using OpenGL rendering calls. It renders the data set for a pre-specified amount of time or number of frames with animation between frames. Finally, it outputs the results. SPECviewperf reports performance in frames per second. Other information about the system under test -- all the rendering states, the time to build display lists (if applicable), and the data set used -- are also output in a standardized report. A "benchmark" using SPECviewperf is really a single invocation of SPECviewperf with command-line options telling the SPECviewperf program which data set to read in, which texture file to use, what OpenGL primitive to use to render the data set, which attributes to apply and how frequently, whether or not to use display lists, and so on. One quickly realizes that there are an infinite number of SPECviewperf "benchmarks" (an infinite number of data sets multiplied by an almost infinite number of command-line states). Windows users can download a patch to upgrade from SPECviewperf 7.0 to the new version. It is highly recommended that users with SPECviewperf 7.0 download the patch. The complete version of SPECviewperf 7.1 is a large file (~288MB) and requires much longer download times. New users can download a complete version of the new benchmark. Download & More Information
