Have installed and uninstalled a number of times and nothing works.
Current version: Brand new Mac Pro 2x2.26. Slot 1, GTX285; slot 2, GT120; slot 4, raid controller. Monitor on the 120.
Installed drivers for the 285. It appears just fine. Both cards seen in the system profiler.
Installed toolkit 2.2. Had a lot of trouble with that earlier as the kext box appears unchecked by default in my machine, but now it’s installed.
$ kextstat | grep CUDA
106 0 0x59d000 0x2000 0x1000 com.nvidia.CUDA (1.1.0) <5 2>
Variables as per instructions:
Installed sdk 2.2. (I did rm -r the whole /Developer/CUDA tree prior to install). Made. Got trivial warnings.
CUDA Device Query (Runtime API) version (CUDART static linking)
There is no device supporting CUDA.
Device 0: “Device Emulation (CPU)”
CUDA Capability Major revision number: 9999
Previously, downgrading to 2.1 I had got completely nonsensical results (deviceQuery would return a single card, rather than 2, with a null string name, negative clock rate, 1 byte of RAM…). I removed the GT120, moved the monitor to the 285, repeat, same thing.
Will repeat again with 2.1 to see if the nonsensical part still keeps coming up.
Any clues are welcome—pretty please?
