I've just grabbed the 8.501 (8.6) release of the Catalyst driver for Linux, which I note is a higher release number than that of the driver with SDK 1.1. I'm using a Radeon 3870. Is the 8.501 Linux Catalyst driver what I should be using?
Also, In Brook+ do the Kernel intrinsics work with double or only float numbers. So should
b = cos(a);
work. (So far it doesn't work for me).
