Grand Central Dispatch

The main topic of discussion today between myself and Stu is a new Snow Leopard Mac OS X 10.6 technology called Grand Central Dispatch. The technical brief gives an interesting glimpse, with enough information to get you excited but not enough actually tell you what you need to know to write program.

Of all the features of the new operating system this feature, I think, will be the most discussed by geeky programmers this week. Sure OpenCL is nice, but we've talked about that. More 64-bit is wonderful. Accessibility is cool. But for programmers, multi-threading is a pain that needs sorting out, preferably before the next generation of multi-core chips arrive.

I know there are many solutions and others (Microsoft, Sun...) are producing 'new' solutions. It's an interesting thing to watch and be able to play with. Pity Snow Leopard is Intel only ... maybe a reason to upgrade. Where are those low power quad core laptop chips?
