Certain samples fail with 'no device supporting CUDA'

Accelerated Computing CUDA CUDA Programming and Performance

Hi,

I installed the CUDA SDK and toolkit, taking special care that kext was enabled, set the environment variables on bash_profile and restarted my MacBook Pro. After I restarted, I tried some of the examples. To my satisfaction, the deviceQuery worked fine. But some of the examples failed stating ‘There is no device supporting CUDA’ , while some fail with ‘bus error’ . So, I reinstalled the toolkit, again making sure the kext is checked, and restarted again. But the examples still don’t run.

i am having a similar problem. I’ve got a previous generation of mac book pro with the same info. osx 10.5.5…

randomly some of the examples will run but they get all wonky slow (because i guess it shows i have no cuda device) also on launching it says somthing along the lines of …
Using device 0: Device Emulation (CPU)
which i’m guessing it shouldn’t… thoughts?

D’oh i feel stupid. so you do need to hit custom install and install that CUDA.kext i donno why i did not see that before. my bad.

Hi SurviveStyle, I noticed your issue was resolved by selecting CUDA.kext. My issue turned out to be different actually. I was installed CUDA 2.0 and running samples from 1.5. A few of them ran into issues.

did you fairly put environments variables so your PATH contains /usr/local/cuda/bin, your LD_LIBRARY_PATH contains /usr/local/cuda/lib and your DYLD_LIBRARY_PATH contains /usr/local/cuda/lib ?
