Yeah, but can the Chicoms play Air Guitar on their 2.5 petaflop Tianhe-1A?

Air Force Unveils Fastest Defense Supercomputer, Made of 1,760 PlayStation 3s

Let's see if I can get this right.  A teraflop is 1000 billion flops and a petaflop is 1000 trillion, so the Playstation computer is a ½ petaflopper.  “ The Air Force Research Laboratory (AFRL) has strung together 1,760 PlayStation 3 gaming systems to create what it’s calling the fastest interactive computer system in the entire DoD, capable of executing 500 trillion floating point operations per second. At a total cost of about $2 million, the AFRL estimates the cluster costs something like five to 10 percent of equivalent computers built from scratch. It also consumes just 10 percent of the power. The array employs the older model PS3s (the larger ones) because new models don’t allow the installation of Linux, a key component for turning the consoles into pliable computing hubs. The AFRL will use the Condor Cluster for quickly processing high-res satellite imagery, radar enhancement, and even research into artificial intelligence. [Full]
