Advanced Micro Devices (AMD) recently released ATI Stream Profiler version 1.3. ATI Stream Profiler is a Microsoft® Visual Studio® integrated runtime profiler that gathers performance data from the GPU as your OpenCL™ application runs. This information can then be used by developers to discover where the bottlenecks are in their OpenCL™ application and find ways to optimize their application’s performance.

Features of the tool include:

• Measure the execution time of an OpenCL kernel
• Query the hardware performance counters on ATI Radeon graphics cards
• Display the memory traffic from and to GPU
• Compare multiple runs (sessions) of the same or different programs
• Store the profile data for each run in a csv file
• Display the IL and ISA (hardware disassembly) code of the OpenCL kernel
