Visualization Team Develops Benchmark for Scientific Graphics Software

September 1, 2008

The NERSC Analytics Team has developed a benchmark for the high performance graphics industry standard OpenGL, called svPerfGL. This benchmark focuses on measuring OpenGL rendering performance in the presence of extremely heavy graphics payload with relatively few OpenGL state changes, which is a typical of a workload incurred by scientific visualization applications.

In contrast, industry standard benchmarks like SPECviewperf generate workloads typical of CAD and gaming applications, which do not always apply to science visualization. svPerfGL is written in a combination of C and C++ and uses calls consistent with the OpenGL 1.2 specification. Therefore, it is very conservative in its use of the OpenGL API and should run on any modern platform that supports OpenGL. It has undergone formal LBNL technology review and release and is currently available under an open source license. For more information and a link to download, please visit
