ATI Radeon HD4570 OpenCL problems

Hi everyone!

I have some problems with running ATI Stream SDK's samples on GPU.

My hardware: ASUS K50AB notebook with GPU ATI Mobility Radeon HD4570 512 Mb.

When I launch HelloCL example with CL_DEVICE_TYPE_GPU the output is:

Creating a context
For test only: Expires on Sun Feb 28 00:00:00 2010
Getting device info
Number of devices: 1
Loading and compiling CL source
Program::build() failed (-11)


Other samples work when launched with --device gpu parameter, but execution speed is the same as with cpu version.


Am I doing something wrong or is there some way to make it work?


I have latest ATI drivers from here http://developer.amd.com/GPU/ATISTREAMSDKBETAPROGRAM/Pages/default.aspx installed.

OS - Vista.

Stream SDK - 2.0 beta4 (latest)
