a bit more about Grand Central

Had Daniel Eran Dilger of RoughlyDrafted Magazine been in attendance at Apple's WWDC, he would now be in violation of the NDA covering all aspects of the conference aside from the keynote address. As he wasn't, that blood is on someone else's hands, whoever passed the information he presents here along to him.

Much of that article is simply placing news that was already public in context, but there are a few tidbits that hadn't appeared elsewhere.

With regard to Grand Central, after describing how packet-switched networks are more robust than circuit-switched networks, Dilger writes:

"Snow Leopard’s Grand Central Dispatch does the same thing for processes, packetizing tasks into Blocks and routing them to available processing cores as efficiently as possible. It can also manage the big picture for the whole system, adjusting how it balances its tasks as the performance load increases. This would be close to impossible for Individual developers to do themselves."

That's not much, but it's more than those of use who weren't at WWDC already knew.
