ATI’s Stream KernelAnalyzer (or SKA) is an utility for analyzing the performance of stream kernels on Radeon and FireStream graphics cards.
Cool… but what are stream kernels?
A stream kernel is the same thing than NVIDIA CUDA kernel: a function that processes data and is executed in parallel by all GPU threads or stream processors. In a word, if you’re doing GPGPU programming with the ATI Stream SDK, this is an useful tool to improve the speed of your kernels.
