There have been a few different clusters that have surpassed PC's but this network hit one petaflop of computing power (the equivalent of 1,000 trillion calculations per second) and placed itself in the Guinness World Records as the world's most powerful distributed computing network.

I don't understand. Are these chips in every PS3, and do they enable outside users to use functions on unknowing PS3 owners consoles?

Yes they have the same chips on them as you will have on your home console. The difference is that they have clustered (http://en.wikipedia.org/wiki/Computer_cluster) them together.
