I have downloaded and installed the latest SDK on my Windows 7 machine with an ATI Radeon HD 4350, which reportedly has a max. work group size of 128.
However, when I run the FFT sample from the SDK, I get:
Error : Out of resources!
Work-group size required by kernel : 64
Maximum size supported on GPU for this kernel : 32
I assume I should be able to execute a simple FFT with this hardware and am doing something wrong. Any help is appreciated.
If I reduce the local and global thread count to 32 from 64, it does execute. Does my Radeon HD 4350 have a smaller maximum work group size than what a utility (GPU Caps Viewer) is reporting?
