So, I’ve been drooling over finally having a nice laptop, which will allow me to do some CUDA development without tying me to my desk. I went out and got the new MacBook (you know solid aluminium…etc). Totally filled with excitement I immediately download the CUDA toolkit and SDK to see just what it can do.

Well, as it turns out not much. I was actually seeing a psychotic flickering while running the nbody simulation. Turns out there is a quick fix, which boggles the mind as to why it wasn’t on by default. Thus I share with you. During the installation of the CUDA toolkit, you must select “Customize” during the install and select to install the CUDA kext. After which you should be ready to run some major amounts of data.

What remains so odd about this is that the kext should have been installed by default, even the description of this install option it says something like “allows you to use CUDA”.. I mean WTF so I’d be installing the toolkit and not wanting to use it?

25-30 Gflops later..I am a very, very happy camper.
