Host-Side Timing

The following code snippet is a host-side timing routine around a kernel call (error handling is omitted):
float start = …;//getting the first time-stamp         clEnqueueNDRangeKernel(g_cmd_queue, …);         clFinish(g_cmd_queue);// to make sure the kernel completed float end = …;//getting the last time-stamp float time = (end-start);
In this example, host-side timing is implemented using the following functions:
  • clEnqueueNDRangeKernel
    puts a kernel to a queue and immediately returns
  • clFinish
    explicitly indicates the completion of kernel execution. You can also use
Remember to profile operations on memory objects separately.
