i want to tune my OpenCL application with Vtune. so i just follow the instructions to profile my project with Vtune.
here is the url : http://software.intel.com/sites/landingpage/opencl/user-guide/index.htm
However only i can see is the collecting data for host code. i cann't find the cycle for my kernel.
Did i miss some setting for my Vtune project? I will be glad if someone can help me or send me a teaching video or document to profile the OpenCL sample.
And i will list the steps i have done for my setting.
step1. download the Intel® VTune™ Amplifier XE 2013 and install it.
step2. open the Vtune gui and create a new profile project
step3. open the Project Properties window, and add two lines to the User-defined Environment Variables table:
step4. also include the execution file of my openCL application, this appication is a simple array operation code with adding two element and store the result to another array.
and the name of my kernel function is hello_world
step5. then i press the start button, and the Vtune report the result. But i can not fine any information about the kernel.
