4 TB of memory
384 Xeon ES-2600 cpu's
Built in fiber optic networking between cpu's; 500 GB/s switching ports
66 TFlops per cabinet, and yes these specs are per cabinet so they can be ran in multiple parallel configurations.
Why? If I had the money to buy one of these, I'd have enough money to run one of these(note the 88kW PSU a single cabinet uses). That means I'd farm out F@H immediately, completely decimate BOINC(WCG), and start a laundry list of Universities' projects. Not to mention host the biggest massive BitTorrent server network in the world. Deploy this in Kansas City with a direct fiber network to Dallas to LA, and from Chicago to NYC; completely under mind all the current cable companies(Comcast, Time Warner, ect) by delivering free services and watch the market drop out. Partner with Google on developing Fiber Optic nodes to EVERY home, push the 1Gb/s throughput and advance scientific research to ground breaking technologies that develop pure wireless energy transfer. Realize NASA's budget for the next 100 years is fully funded through the donations I've received by providing free services to everyone in the country/world; help design and build the first intergalactic space station and be the first to visit Alpha Centauri(nearest star, like 4 light years from the sun). Become Universally known for the single most advancement of any race and live long and prosper.
Hey, why not. I was always taught to dream big.
