WebJan 1, 2016 · We propose CUDA-quicksort an iterative GPU-based implementation of the sorting algorithm. CUDA-quicksort has been designed starting from GPU-quicksort. Unlike GPU-quicksort, it uses atomic primitives to perform inter-block communications while ensuring an optimized access to the GPU memory. WebMay 8, 2014 · This post Sorting objects with Thrust CUDA may already contain some useful information. I'm afraid that the slowness is related to the fact that you are using Arrays of Structs and not Structs of Arrays which as to do with non-optimal global memory accesses. – Vitality May 8, 2014 at 13:34 Tens of minutes sounds like something is broken.
