Aussie scientists build a cluster to map the sky

Tri writes: "Scientists at the Siding Spring Observatory have built a new system that maps and records over 1 billion objects in the southern hemisphere sky. They collect 700 GB of data every night which they then crunch down using some perl scripts and make available to other scientists through a web interface backed on Postgresql. They've also got a system with over 12,000 cores which they use to process the data."
