Evaluating Nonuniform Reduction in HIP and SYCL on GPUs
DescriptionMotivated by maturing programming models and portability for heterogeneous computing, we describe the challenges posed by hardware architectures and programming models when migrating an optimized implementation of nonuniform reduction from CUDA to HIP and SYCL. We explain the migration experience, evaluate the performance of the reduction on GPU-based computing platforms, and provide feedback on improving portability for the development of the SYCL programming model.
