AMD and Cray are building the 'world's most powerful supercomputer'
The US may be set to hang onto the crown of having the world's most powerful supercomputer for some time. Cray Computing and AMD are building an exascale machine with the Oak Ridge National Laboratory. The system is set to debut in 2021, the same year Cray and Intel are scheduled to deliver the Aurora exascale supercomputer to the Argonne National Laboratory.
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.
Cray XK6 supercomputer smashes petaflop record, humbly calls itself a 'general-purpose' machine
Sure, IBM's ten petaflop supercomputer may sound impressive, but Cray can do you five better -- the outfit just announced the Cray XK6, an upgradable, hybrid supercomputing system capable of more than 50 petaflops of computational muscle. Powered by Cray's Gemini interconnect, AMD Opteron 6200 processors, and NVIDIA Tesla 20-Series GPUs, the XK6 system blends x86 and GPU environments with the firm's own flavor of Linux. The folks at Cray won't resort to bragging, however -- they're humbly declaring the machine to be the first "general-purpose supercomputer based on GPU technology," and not, as they put it, a stunt to place high on any Top 500 lists. Suggestive, aren't they? Check out the unassuming press release after the break.
Homebrew Cray-1A emulates the iconic supercomputer, to no useful purpose
The Cray-1A first made the scene in 1976, weighing 5.5 tons (including the refrigeration system) and running at 80MHz -- with a whopping 8MB RAM. Who wouldn't want to own one -- or a miniature version of one, for that matter? Chris Fenton would, apparently. Yes, it's that Chris Fenton -- the electrical engineer who once made a $50 laptop out of a PICAXE 18X Microcontroller and 96 bytes of RAM (and some wood). And he's back with a 1/10-scale Cray-1A. And unlike a similar project we've seen in the past, this bad boy runs a custom Cray emulator (too bad there doesn't seem to be any Cray software floating around). Wild, huh? Get the whole scoop (and some pointers if you want to roll your own) after the break.
Honey, Daryl Brach shrunk the Cray-1 supercomputer
The original Cray supercomputer, the Cray-1, is an iconic piece of computing history, so big it had a ring of padded seats around which engineers could sit and contemplate esoteric questions of life whilst the machine humming behind them answered the more finite ones. This semi-hexadecagon shape has been brought back to life, scaled down quite a bit, by case modder and woodcrafter Daryl Brach. The original 5.5 ton behemoth is now a desktop-friendly size, and though those seats are now too small for human behinds they're still leather-covered and padded, hiding a pair of DVD-ROM drives connected to not one but two motherboards. We're not sure what other hardware Brach populated the thing with internally, but given that original Cray-1 had 8MB of memory to work with we're guessing this modern version would have no problem computationally wiping the floor with its inspiration.
Roadrunner beats Jaguar in TOP500 supercomputer rankings, cartoon antics strangely absent
While titles like "world's fastest" and "world's largest" are fleeting at best, it's rare that we see such things taken down this quickly. Last week Cray delivered a big dish of braggadocio, talking up its 1.64 petaflop XT Jaguar supercomputer as the fastest (non-classified) machine in the world. Now, like some rocket skate-wearing coyote who's run out of thrust, it's been stymied by IBM's Roadrunner, deployed at Los Alamos. TOP500 is the authority on these matters and that list's latest rankings place Roadrunner in first place with a speed of 1.105 petaflops; Cray's Jag comes in second with a paltry 1.059. What about that 1.64 figure from last week? That was the hypothetical limit, and while it did deliver real-world performance of 1.3 petaflops for the folks at Oak Ridge, TOP500 relies on the Linpack benchmark for its ratings and apparently the Jag just couldn't deliver the goods there. Perhaps, Cray, it's time to make another call to ACME -- or AMD as it were.
Cray supercomputer is world's fastest (that we're allowed to know about)
Seattle-based Cray has been wowing us with massive, ridiculously fast supercomputers since the '70s, establishing a position for its machines high on every geek's most wanted list -- despite never publishing a Doom benchmark. In recent years the title of "world's fastest" supercomputer had been lost by the company, ping-ponging from Wako, Japan to Armonk, NY, but is now back in Cray's hands with the implementation of the XT Jaguar. It's comprised of over 45,000 quad-core Opteron processors, 362GBTB of memory, and has a 10PB (petabyte) storage array, able to perform calculations at a massive 1.64 petaflops. That's over one and a half quadrillion operations per second and more than 50 percent faster than IBM's previous heavyweight. Mind you, Cray is quick to point out that this is the fastest machine being used for non-classified research, a caveat that just makes us even more curious about what's keeping the Pentagon's server rooms warm and loud... and apparently orange. Update: That should be 362 terabytes of memory, not mere gigabytes.[Via UPI.com]
