Measurement and Analysis of GPU-Accelerated OpenCL Computations on Intel GPUs

Graphics Processing Units (GPUs) have become a key technology for accelerating node performance in supercomputers, including the US Department of Energy’s forthcoming exascale systems. Since the execution model for GPUs differs from that for conventional processors, applications need to be rewritten to exploit GPU parallelism. Performance tools are needed for such GPU-accelerated systems to help d...
