Mohit2710,

      I am not sure what tool you are looking. Presently No tool available to profile OpenCL kernel in linux.  Hand tuning is the only way at this stage. 

Please see the Preformance and Optimization notes doc at http://developer.amd.com/gpu/ATIStreamSDK/pages/Documentation.aspx

for more details.

Use your own timer code or OpenCL profiling API's to calculate performance calculation.

Mohit2710,

         which cache performance you are talking about?.  Are you running your code on CPU or GPU?  Even profiler won't say anything about cache.

I am running my code on CPU Intel Core2Duo T6400 @ 2.00 GHz with 2.00 MB cache size.

My code does not give proper results for higher block sizes and what could be he possible reasons for for this, I can think of limited cache size as a reason. Can you suggest any other reason.

Also about the tools that can be used to check this.

Mohit2710,

               Could you please post your code?  You have to use AMD codeanalyst or Intel VTune to profile your code on CPU.
