Today, most CPU+Accelerator systems incorporate NVIDIA GPUs. Intel Xeon Phi and the continued evolution of AMD Radeon GPUs make it likely we will soon see, and want to program, a wider variety of CPU+Accelerator systems. PGI already supports NVIDIA GPUs, and is working to add support for Xeon Phi and AMD Radeon. Here we explore the features common to all three types of accelerators, those unique to each, and the implications for programming models and performance portability from a compiler writer’s and application writer’s perspective.
