CUDA device found by deviceQuery on Macbook White with 9400M

Hi All,

I am new to this forum.

I have a Macbook white with Nvidia GPU 9400 M . I would like to use it to run my CUDA based programs. So I have installed the Driver, Tool Kit and SDK. I have Installed the proper driver version 2.3.

But while I run the deviceQuery from the desired location it shows the following message -


CUDA Device Query (Runtime API) version (CUDART static linking)
There is no device supporting CUDA.

I have tried to look for the solution provided in the forum; unfortunately I was not able to decipher it. I am not able to find customize the tool kit, driver or the SDK installation. Somebody also mentioned about the KEXT modification; this is also not clear to me.

So my query is –

  1. Can my Macbook support CUDA and is there way to communicate with the 9400M device?
  2. How can I do that?

Thanking you all in advance,

Best regards,
Nil

reinstall the driver, there’s a bug with the toolkit installer where it will wipe libcuda.dylib (the CUDA driver) if you install it after the driver

Hi,

Thanks a lot man!

It did worked fine after I installed the Driver again.

Cheers,

Nil
