What is Improving Performance of OpenCL Workloads on Intel Processors with Profiling Tools about?

We present techniques for improving OpenCL workload performance with Intel profiling tools on modern heterogeneous hardware. We discuss how the profiling tools interface with heterogeneous hardware and the hardware's correspondence with architectural metrics derived from profiling. By leveraging metrics, we demonstrate improvements to OpenCL workload subscription of hardware with particular attention paid to CPU versus graphics coprocessor residency. With source code examples, we observe metrics to show the performance advantages of contemporary OpenCL extensions such as subgroups, as well as extensions enabling access to special function hardware features outside of the standard execution unit array.
