ERROR: Unable to get device_id

Can't get OpenCL to work on Win 7 and VS2010

Hi,

I am using Visual Studio 2010 on a Dell Precision T3500 workstation. It has a Intel Xeon quad-core CPU and an ATI FirePro 4800 graphics card. I installed the latest AMD APP SDK and followed all the instructions given in the "Introduction to OpenCL Programming" guide and tried to get the "Helloworld" program running -- but it is not. It gives the error -- "unable to get device_id".

 

When I run the "clinfo" program, I get the following output:

UPDATE:

  1. I checked the requirements for SDK 2.4 and it needs 8.841 drivers. But those do not support FirePro V4800. (please correct me if I am wrong here).
  2. I uninstalled V2.4 of the SDK and installed V2.01 of the SDK. Now my GPU is detected and all the samples run fine. It does not give an error message "Rolling back to the GPU".
  3. I might have missed a lot of support by using V2.01. If so, please can you tell me what I can do to get V2.4 working?

Thank you !
