I have a float point calculation code and sometimes it gives different results than what it gets in most runs.
Sometimes I use "cl-opt-disable" and sometimes I just use "" for compiling the kernel.
As far as I know, there should be no racing conditions.
My GPU card is NVIDIA GTX 9800/GTX 9800+. I think the compute capability is 1.1 or 1.0. The device version is 1.0.
