Visualization Team Develops Benchmark for Scientific Graphics Software
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… Read More »
