Want big data? Really big data? Consider the following description from 550 billion particles:
The amounts involved in this simulation are simply mindboggling: 92 000 CPUs, 150 PBytes of data, 2 (U.S.) quadrillion flops (2 PFlop/s), the equivalent of 30 million computing hours, each particle has the size of the Milky Way, and so on…
