I wouldn't be surprised if they used 1500 for the computer and distributed the rest to various Pentagon offices.The US Department of Defence has unveiled its fastest interactive computer - made out of 1,760 Playstation 3 consoles.
Dubbed the Condor Cluster, the new system is capable of performing 500 trillion floating point operations per second.
It will be used for quickly processing high-res satellite imagery, radar enhancement, and even research into artificial intelligence.
The consoles were used as they provide maximum computing power at a budget price.
