Suggestion : OpenCL Optimization Guide

Hi,

I think that we miss an "Optimization guide" which present :

- basic principles/techniques of optimization (use of float4, ...)

- present several paterns (like reduction)

- explain how to optimize for ATI GPU (Based on GPU Architecture)

Any other tips...

 

Regards

The optimization chapter in the programming guide is pretty thorough. Do you feel that's not enough?

A few more performance samples would be helpful, though, I agree.

Section 4-31 talks about float4, for example.
