Abstract

In this paper, we propose a fast and flexible sorting algorithm with CUDA. The proposed algorithm is much more practical than the previous GPU-based sorting algorithms, as it is able to handle the sorting of elements represented by integers, floats and structures. Meanwhile, our algorithm is optimized for the modern GPU architecture to obtain high performance. We use different strategies for sorting disorderly list and nearly-sorted list to make it adaptive. Extensive experiments demon- strate our algorithm has higher performance than previous GPU-based sorting algorithms and can support real-time applications.
