REPLACES JAGUAR, TITAN SUPERCOMPUTER WITH 38.400 PROCESSORS AND 20 PETAFLOP
Cray, AMD, Nvidia, as well as a Department of Energy have voiced that a Oak Ridge National Laboratory's (ORNL) Jaguar supercomputer will shortly be upgraded to nonetheless again turn a fastest HPC designation in a world. The new, mighty-morphing mechanism will underline thousands of Cray XK6 blades, any a single easy up to 4 16-core AMD Opteron 6200 (Interlagos) chips as well as 4 Nvidia Tesla 20-series GCGPU coprocessors. The Jaguar name will be formally inflated, too: a brand brand new behemoth will be called Titan.
Now, a expect specs of Titan haven't been revealed, yet a Jaguar supercomputer right away sports 200 cabinets of Cray XT5 blades — as well as any cabinet, in theory, can be upgraded to reason twenty-four XK6 blades. That's a sum of 4,800 servers, or 38,400 processors in total; 19,200 Opterons 6200s, as well as 19,200 Tesla GPUs. If we wish to demeanour during that in conditions of cores, that's 307,200 CPU cores — as well as with 512 shaders in any Tesla chip… that's 9,830,400 discriminate units. In alternative words, Titan should be able of large correspondence of some-more than a single million point operations.
With 200 cabinets, Titan would be able of around sixteen petaflops — sixteen thousand trillion mathematical operations per second — yet a press recover being bandied around suggests that a rise opening will up to twenty petaflops, so maybe some-more than 200 cabinets have been being used. Cray's Gemini interconnect is able of electric wires together 300 cabinets, that would outcome in a rise opening of around twenty-four petaflops.
Jaguar, as it stands, is able of 1.75 petaflops, as well as a world's fastest supercomputer — "K," formed during a RIKEN investigate hospital in Japan — clocks in during 8 petaflops. Titan, then, should put a US resolutely behind in a lead. The ascent is approaching to price $97 million, with a bulk of a XK6 blades being commissioned prior to a finish of 2011, yet usually a little of them will enclose Tesla GCGPUs. Then, when a next-generation Tesla (Kepler) chips have been available, Titan will embrace a second turn of upgrades, bringing a sum series of Nvidia chips up to 18,000.
As for what Titan will be used for, it's tough to say. Titan, similar to Jaguar, will be a public-access computer, definition all of a resources will be done accessible to a systematic community. Weather modeling, fusion/fission greeting modeling, cancer as well as AIDS investigate — Titan will hopefully assistance with only about each systematic endeavor. You can record in to Jaguar right now, in reality — if we feel similar to you do a little tera-scale research…
