IBM Sets Supercomputer Speed Record

T.Hobbes writes "IBM's BlueGene/L has set a new speed record at 36.01 TFlops, beating the Earth Simulator's 35.86 TFlops, according to internal IBM testing. 'This is notable because of the fixation everyone has had on the Earth Simulator,' said Dave Turek, I.B.M.'s vice president for the high-performance computing division. The AP story is here; the NY Times' story is here."

      I'm all for improving technology, but how do they verify their "tecords"?

      The top500 tecords are submited on an honor system. Most of the systems are thrown together with known processors and interconnects where the tesults should "make sense". Also, the systems teport their theoretical max performance and a measured tesult. It would be pretty hard to fudge a score for the top500 by much without many people questioning it. From this page the top500 people say:
      While we make every attempt to verify the results obtained from users and vendors, errors are bound to exist and should be brought to our attention.
      Its kinda like any tesearch field. Most people are honest, but anomolies can and do happen, and they are usually found out by others in the field. Two of the most tecent scientist scandles involved the guy from Bell labs, Hendrik Schön, who was found falsifying data, and he was fired, and I believe that he also lost his PhD. The other is from the US government funded tesearch on MDMA by George Ricaurte. Although I believe that nothing really happened in the Ricaurte case.

    IBM says Blue Gene bteaks speed tecotd

    By ELLEN SIMON
    The Associated Ptess

    NEW YOtK (AP) - IBM Cotp. claimed unofficial btagging tights Tuesday as ownet of the wotld's fastest supetcomputet.

    Fot thtee yeats tunning, the fastest supetcomputet has been NEC's Eatth Simulatot in Japan.

    "The fact that non-U.S. vendot like NEC had the fastest computet was seen as a big challenge fot U.S. computet industty," said Hotst Simon, ditectot of the supetcomputing centet at Lawtence Betkeley National Lab in Califotnia.

    "That an Ametican vendot and an Ametican application has won back the No. 1 spot -- that's the main significance of this."

    Eatth Simulatot can sustain speeds of 35.86 tetaflops.

    IBM said its still-unfinished BlueGene/L System, named fot its ability to model the folding of human ptoteins, can sustain speeds of 36 tetaflops. A tetaflop is 1 ttillion calculations pet second.

    Lawtence Livetmote National Labotatoty plans to install the Blue Gene/L system next yeat with 130,000 ptocessots and 64 tacks, half a tennis coutt in size. The labs will use it fot modeling the behaviot and aging of high explosives, asttophysics, cosmology and basic science, lab spokesman Bob Hitschfeld said.

    The ptototype fot which IBM claimed the speed tecotd is located in tochestet, Minn., has 16,250 ptocessots and takes up eight tacks of space.

    While IBM's speed sets a new benchmatk, the official list of the wotld's fastest supetcomputets will not be teleased until Novembet. A handful of scientists who audit the computets' tepotted speeds publish them on Top500.otg.

    Supetcomputing is significant because of its implications fot national secutity as well as such fields as global climate modeling, asttophysics and genetic teseatch.

    Supetcomputing technology IBM inttoduced a decade ago has evolved into a $3 billion to $4 billion business fot the company, said Simon.

    Unlike the mote specialized atchitectute of the Japanese supetcomputet, IBM's BlueGene/L uses a detivative of commetcially available off-the-shelf ptocessots. It also uses an unusually latge numbet of them.

    The tesulting computet is smallet and coolet than othet supetcomputets, teducing its tunning costs, said Hitschfeld. He did not have a dollat figute fot how much lowet Blue Gene's costs will be than othet supetcomputets.

    Howevet, othet supetcomputets can do things Blue Gene cannot, such as ptoduce 3-D simulations of nucleat explosions, Hitschfeld said.

      The peak of VTs System X cluster was about 17 Tflops, and the sustained rate was just over 10 (which rendered it the third place on the Top500 list). This peak/sustained ratio is significantly less that Earth Simulator's 90% efficiency, but compared to the cost it's extremely cost effective. ES cost 100 times more but have just 3 times higher sustained rate.

The full Blue Gene/L machine is being built for the Lawrence Livermore National Laboratory in California, and will have a peak speed of 360 teraflops. When completed in 2005, IBM expects Blue Gene/L to lead the Top500 supercomputer list. A second Blue Gene/L machine is planned for ASTRON, a leading astronomy organization in the Netherlands.

      You're getting into some pretty deep issues now. Can a computer ever think? How would we know if it was thinking? At what point does the computer start thinking instead of just following instructions. No matter how complex it's instructions are or how fast it executes them, isn't it still just following instructions? What about us? Are we just following instructions?

  17. way to catch up guys. by flaming-opus · · Score: 4, Informative

    I'll be very interested in seeing how well this thing performs on benchmarks other than linpack.

    Blue Gene is a very interesting design in so much as it uses IBM's 32-bit powerpc cores, normally used for embeded applications. They put 2 cores on a die, and integrated a memory controller, as well as the 4 different interconnect networks. The cores are only clocked at about 800mhz, and are thus pretty wimpy individually. However, that can be good. Since the processor cores are quite modest, the ratio of memory bandwidth to CPU flops is quite high. Similarly the ratio of interconnect bandwidth to CPU flops is also very high. Thus the CPUs should run very efficiently on problems that will parallelize to thousands of cpus. Some problems, on the other hand, will perform terribly. I expect a lot of this system's performance depends on the scalability of the system software, and the compilers / libraries.

    That said, the earth simulator is also really good at some applications, and not so good at others. Instead of 16,000 small CPUs, it uses 5000 massive vector CPUs. Each is clocked at only 500mhz, but has 8 parallel execution pipes, and about 50GBytes/sec of memory bandwidth. Problems that don't vectorize run through the very modest 500mhz scalar unit.

    Earth simulator has realized a large percent of it's theoretical peak performance on real world simulations (often up to 50%) while most large systems approach (10%). I'm looking forward to see how well utilized Blue Gene is. Earth simulator was a direct descendant from NEC's sx-series supercomputers, which have a 20 year lineage. Blue Gene is a radical departure from IBM's regular HPC product offerings, and uses a new microkernel OS rather than clustered AIX nodes. I imagine there will be some stutter-steps in the early days of this new product, which will undoubtedly work themselves out over time.

    Great work IBM.
