A few days ago I finally upgraded to Snow Leopard. I was writing a few grants, so I did not want to take the chance to upgrade before submitting these grant applications. Anyway, I am now running Snow Leopard, and even though there are no “new” apparent features, it is a great upgrade. In my opinion, the best of all OS X upgrades so far, as it really brings great improvement under the hood, including “full” 64 bit support, openCL, and Grand Central Dispatch. For more details check out the Apple webpage. To say the least, I am very exited about Grand Central and trying to use it in some of our work. I thought it would be rather complicated to take advantage of it, but in fact it looks pretty easy. The folks at macresearch have posted a simple example that makes me want to try it ASAP. It looks even easier than openMP, and perhaps more efficient.

I will try to post an update as soon as we have tried it.
