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. What's New in Version 1.3 * Support data transfer for image objects. * Added five new performance counters: FetchMem, L1CacheHit, LDSFetch, LDSWrite, and LDSBankConflictAccess. * Added three shader compiler statistics: GPR, scratch register, and flow control stack size used by the kernel. * Added support to view the CL kernel source in the CodeViewer panel. * Added support to view the x86 assembly for CPU device in the CodeViewer panel. * Temporary files are now stored in the ProfilerOutput directory. * Improved Counter Selection Window. * Improved results for ATI Radeon™ HD5770 and ATI Radeon™ HD5570 graphics cards. * Report the API name for the data transfer operations and updated the unit from bytes to kilobytes. * The kernel name is now appended with the kernel handle to differentiate kernel dispatches for kernel with the same name but different contents.
