Cray's Jaguar supercomputer upgraded with NVIDIA Tesla GPUs, renamed Titan
Cray's Jaguar (or XK7) supercomputer at Oak Ridge National Laboratory has been loaded up with the first shipping NVIDIA Tesla K20 GPUs and renamed Titan. Loaded with 18,688 of the Kepler-based K20s, Titan's peak performance is more than 20 petaflops. Sure, the machine has an equal number of 16-core AMD Opteron 6274 processors as it does GPUs, but the Tesla hardware packs 90 percent of the entire processing punch. Titan is roughly ten times faster and five times more energy efficient than it was before the name change, yet it fits into the same 200 cabinets as its predecessor. Now that it's complete, the rig will analyze data and create simulations for scientific projects ranging from topics including climate change to nuclear energy. The hardware behind Titan isn't meant to power your gaming sessions, but the NVIDIA says lessons learned from supercomputer GPU development trickle back down to consumer-grade cards. For the full lowdown on the beefed-up supercomputer, hit the jump for a pair of press releases.
NVIDIA outs a pair of Tesla GPUs to electrify your supercomputer
NVIDIA's announced a pair of Tesla GPUs that'll give some extra pep to your supercomputing tasks. The K10 and K20 units harness the power of Kepler to add more muscle to the company's scientific and technical computing arm that supplies gear to the Barcelona Supercomputing Center and Tokyo's Tsubame 2.0. Internal tests reveal that the hardware is around three times faster than the company's Fermi GPUs -- with the latter card expected to arrive at the end of the year. The company didn't announce pricing, since its aiming them squarely at the big academic institutions, defense contractors and oil explorers -- but if your surname is Buffet or Abramovitch, then they might sell you one at trade.
