Developer Guide for Intel® SDK for OpenCL™ Applications
To profile kernels using the Deep Kernel Analysis feature of the Intel® SDK for OpenCL™ Applications standalone version, do the following:
If desired, mark any of the possible OpenCL code lines for profiling by clicking the red circles on the left of your code lines. The marking can be undone by clicking the filled circles (toggling on and off).
Do not use the Auto feature for best local group size configuration with Deep Kernel Analysis. Define a single group size for both global and local for each dimension used.
