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:

HelloCL!
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)

Hmm. Error code -11 indicates CL_BUILD_PROGRAM_FAILURE.. i suppose this may be a critical compiler error, can you retrieve and output the build info from the program?

Also Number of Devices: 1 is odd, since your laptop should at least have two devices: the GPU and the CPU. Can you query the device for type, name etc.?

I've tried new Stream SDK 2.0, and while installation it says that my display driver doesn.t support gpu opencl.

My current driver: ATI Technologies Inc., 17.08.2009, 8.632.1.2000. I tried also 8.673.00, but it didn't work (and max resolution was 1024x768 instead of native 1366x768). Catalyst 9.12 hotfix for non-mobile radeon version didn.t work.

What display driver I need for running gpu version of OpenCL?!

I did, but latest manufacturer's driver didn't help.

 

Try Mobility Modder.
