IBM Building 20 Petaflop Computer For the US Gov't 248

eldavojohn writes "When it's built, 'Sequoia' will outshine every super computer on the top 500 list today. The specs on this 96 rack beast are a bit hard to comprehend as it consists of 1.6 million processors and some 1.6TB of memory. That's 1.6 million processors — not cores. Its purpose? Primarily to keep track of nuclear waste & simulate explosions of nuclear munitions, but also for research into astronomy, energy, the human genome, and climate change. Hopefully the government uses this magnificent tool wisely when it gets it in 2012."

HyperThought is massively parallel, it contains neural networks, it has teraflop speed., etc. The computer scientists give HyperThought a shakedown run. It easily computes Pi to 10000 places, and factors a 100 digit number. The scientists try find a difficult question that may stump it. Finally, one scientist exclaims: "I know!"

I would think that 20 petaflops and a good algorithm would be able to produce a processor that is an improvement over the current generation. Then again, I know next to nothing about processor design, so I could be totally wrong.

The issues whilst similar for multi-socket and multi-core systems are different due to the single processor having links to system bus and main memory shared between the cores, where as these are separate links on different processors.

    - IBM is building a computer that will be functional in about 3.5 years.

    - The power of this computer, in 3.5 years, will outshine every other supercomputer currently running today.

      If you have a look at http://top500.org/lists/2008/11/performance_development [top500.org] it takes more than 6 years to get 10 times actual performance (quicker than Moore's law, hrm). Given that the actual top is at 1PF, going to 20 in 3.5 years is quite an achievement.

      Furthermore, 20 vs. ~1.5 petaflops is a goodly sized jump for 3ish years, isn't it? Computer speed growth has seemed to be slowing lately, with an emphasis being on multiple cores, not faster clock speeds like it was 10 years ago. So being able to get 20x the power of the current super
