This is what you probably will get once the image is scaled by your software: How much did you pay for that software?

Royal Pingdom » A look inside the fastest supercomputer in Europe

The computer, named Jugene, is capable of a massive one trillion computing operations per second. Here are some facts about the Jugene supercomputer: Based on IBM’s Blue Gene/P architecture.Computing capacity: 1 petaflop/second.That equals the computing power of more than 50,000 PCs.294,912 processor cores.Processor type: 32-bit PowerPC 450 at 850 MHz.144 terabytes of RAM.Mounted in 72 racks.Network bandwidth: 5.1 gigabyte/second with a 160 nanosecond latency.Power input: 2.2 megawatts. Wish we could get one of these for Pingdom. Packing those CPUs tightly together Each of the Jugene’s 72 racks has 1024 compute nodes, where each node has 2 gigabyte of RAM (totaling 144 terabytes for the whole system). For those of you who really want to dive into the nitty-gritty tech specs regarding Jugene’s setup, here’s more info. Adobe.
