    GPU not found. Falling back to CPU device

    kristen

      Hello -

      I'm having an issue getting OpenCL to work with Radeon HD 6970. When I try to run sample programs from SDK v2.4 (such as 'Histogram') I get the message:

      "GPU not found. Falling back to CPU device".

      I assume that this indicates a problem with the driver? When I run 'fglrxinfo'  it only returns 'Segmentation fault (core dumped)'. I'm working on Red Hat Enterprise Linux release 6.1 with Catalyst 11.4 installed. We initially had the latest driver installed and had the same problem. We then installed Catalyst 11.4 since it is listed as the tested driver on the SDK v2.4 download page, but we still have the same problem.

      I don't have root access and therefore didn't install the driver myself - everything goes through a systems administrator.

      Any suggestions would be appreciated!
