One of NVidia’s useful examples is oclDeviceQuery. This interrogates the OpenCL environment and prints out data about the hardware etc. A useful tool. Will it run with the AMD SDK? Ha ha!
The OpenCL specification describes what needs to be done and the NVidia example follows this quite closely, but it uses various other functions. So, I hacked it! My portable version is here. This compiles and runs on both boxes (and more).
On the NVidia box, the program finds the Tesla C870 and the GeForce 9400.
On the AMD box, it finds one “ATI RV770”.
In neither case are the CPUs found. This led me to some further experiments…
