Analyzing OpenCL™ Kernel Performance

To analyze OpenCL™ kernel performance with the Intel® SDK for OpenCL™ Applications standalone version, do the following:

  1. Click the Analyze button.
  2. Click Refresh kernel(s) to get the list of kernels in the currently open *.cl file.
  3. Select the target kernel from pull-down menu. If only one kernel is available, it is selected by default.
  4. Click cells in the Assigned Variables column to create or add variables as kernel arguments. You can assign one-dimensional variables (such as integer, float, char, half, and so on) on-the-fly by typing single values into the table. See section Creating Variables for details.
  5. Set number of iterations, global size and local sizes per workload dimension in the Workgroup size definitions group box.
  6. Click Analyze to wrap a specific kernel and execute analyses.

You can use the local size(s) text boxes for several different test configurations:
