high performance computing on graphics processing units: hgpu.org

In this thesis work, we have mainly worked on two topics of GPU performance analysis. First, we have developed an analytical method and a timing estimation tool (TEG) to predict CUDA application’s performance for GT200 generation GPUs. TEG can predict GPU applications’ performance in cycle-approximate level. Second, we have developed an approach to estimate GPU applications’ performance upper bound based on application analysis and assembly code level benchmarking. With the performance upper bound of an application, we know how much optimization space is left and can decide the optimization effort. Also with the analysis we can understand which parameters are critical to the performance.
