It is now possible to trace OpenCL commands with the Intel GPA Graphics Performance Analyzer.

The Intel GPA Platfrom Analyzer visualizes the execution profile of the various tasks in your code over a period of time. The tool collects real-time trace data during the application run and provides a system-wide picture of the way your code executes on various CPU and GPU cores in your system. The tool infrastructure automatically aligns clocks across all cores in the entire system so that you can analyze CPU-based workloads together with GPU-based workloads within a unified time domain.
