    Fujitsu's K supercomputer was on our radar before it was even completed, and naturally, we let you know when it smoked the competition and became the supercomputing speed king. So, when we had the opportunity to see a piece of K at Fujitsu's North America Technology Forum today, we couldn't pass it up. In case you forgot, K is a massive machine powered by 864 racks with 24 boards per rack housing SPARC64 CPUs. We got to see one of those boards, and Yuichiro Ajima -- who designed the inter-connection chips (ICC) on them -- was gracious enough to give us some more info on this most super of supercomputers.As you can see in the gallery above, each board has extensive plumbing to keep the SPARC silicon running at a manageable 32 - 35 degrees Celsius (90 - 95 Fahrenheit) under load. Underneath that copper cooling system lies four processors interspersed between 32 memory modules (with 2GB per module) and four ICCs lined up next to the board's rack interconnect ports. Currently, the system takes 30 megawatts to do its thing, though Ajima informed us that K's theoretical max electricity consumption is about double that -- for perspective, that means K could consume the entire output of some solar power plants. When asked if there were plans to add more racks should Fujitsu's supercomputer lose its crown, Ajima-san said that while possible, there are no plans to do so -- we'll see if that changes should a worthy opponent present itself.Update: Turns out the K's power consumption resides around 13 megawatts, with a max consumption of 16MW at its current configuration. The facility in Kobe, Japan where K resides can deliver up to 24 megawatts, so expansion is possible, but none is currently planned.

  • Fujitsu's 10.51 petaflop K supercomputer is fastest in the world

    Fujitsu, sweaty palmed from the construction of the K supercomputer, swore the colossal machine would manage a speed of ten petaflops by the year 2012. The effort has paid off handsomely: the hangar-sized machine has a top speed of 10.51. If you wanted to duplicate that setup at home, you'd only need 864 racks, 88,128 processors and enough cash in your back pocket to front an annual electricity bill of $10 million a year. The company will be spilling all at November's SC11 conference in Seattle, where the K will cement its position as the fastest computer in the world. One last thing -- we have a hunch that this machine can just about play Crysis.

  • Fujitsu K supercomputer will do 10 petaflops in 2012, eat Crays for breakfast

    10's a nice round number, isn't it? Round, yes, but also wildly impressive when you put the word "petaflops" behind it as Fujitsu has done with its upcoming K supercomputer, which will be able to crunch through 10 quadrillion operations every second. Compare that to the current champ of processing farms, Cray's Jaguar, which can handle only (only!) 1.75 petaflops of workload and you'll know that we're talking about a seminal leap in performance. Japan's Riken Research Institute is the fortunate addressee on the crates of ultrafast SPARC64 VIIIfx processors that Fujitsu is now shipping out and the current plan is to have everything up and running by 2012. In total, there'll be 80,000 CPUs, each possessing 8 cores running at 2.2GHz, which will be housed within 800 racks. So yes, there'll be a machine somewhere on the Japanese isle with 640,000 processing cores at its disposal. Feeling safe?
