Abstract :
NVIDIA CUDA and ATI Stream are the two major general-purpose GPU (GPGPU) computing technologies. We implemented RankBoost, a web relevance ranking algorithm, on both NVIDIA CUDA and ATI Stream platforms to accelerate the algorithm and illustrate the differences between these two technologies. It shows that the performances of GPU programs are highly dependent on the utilization of GPU´s hardware memory architectural features. In this work, we accelerated RankBoost algorithm on both platforms, and we achieved 22.9X speedup on CUDA and 9.2X speedup on ATI Stream respectively. Then we made a comparison on the differences of memory architecture between NVIDIA CUDA and ATI Stream.
