IBM Systems Magazine, Mainframe digital edition - May/June 2009 - 27

work on drug design at a pharmaceutical company, because in a commercial conte x t , t he t i me - e qu a l s-mone y equation prevails and if you can compress the timeframe to get a solution, you’re saving money and also giving yourself a strategic advantage over your competitors. You’re producing products more quickly than they are. Time is a great enemy of all people who want to make decisions. The pursuit of speedier computers addresses that problem. But the issue that’s come up is that the incremental benefits we’ve seen over the last 30 years courtesy of Moore’s Law are slowing down. Or to put it a different way, the opportunities to speed solutions are transcended by virtue of employing parallel computational techniques as opposed to the reliance on Moore’s Law as a vehicle by which you’ll get application speedup. So if I can get 50, 100, 10,000, 100,000 processors working in concert on a single problem, maybe there’s a chance I can reduce the time to solution by a 100,000 times—and that’s really, really good. But I can’t do that if all I’m relying on is the next generation of microprocessor from Intel* or IBM. With parallel computing, if I can deploy a system and get a 100,000-times speedup, that’s equivalent to a huge number of years waiting for microprocessor architectures to catch up to a 100,000-time improvement in speed. It’s noncomparable. Q: Are the power savings related to the Cell/BE chip something customers are asking for? A: Every deal we engage in involves a specification of a power budget and often will penalize us or whoever else is bidding on a particular installation for technology that doesn’t fit in that budget. And a lot of times competitors get disqualified from even competing for an opportunity because they don’t have systems that come close to meeting the power budget the client has. That’s 100 percent of all the customers we see today. This phenomenon started to manifest itself probably, I would say, three to four years ago in small numbers. It’s just grown dramatically to the point where everybody looks at a power budget now. Q: Of course, Roadrunner probably isn’t the end of the supercomputing story. What else is on the horizon? A: Well, by now you’ve probably heard of Sequoia, which is scheduled to be delivered to the Lawrence Livermore National Laborator y in 2011, with operational deployment in 2012. With speeds exceeding 20 petaflops, it’ll be 15 times faster than even Roadrunner and—get this—will offer more processing power than all of the supercomputers currently listed on TOP500. This is in part because of the technology behind it, including 1.6 million IBM POWER* processors,1.6 petabytes of memory and a switching infrastructure that will take advantage of fiber optics at all levels. More important, though, is that it’ll occupy only 3,422 square feet and deliver amazing energy efficiencies, at 3,050 calculations per watt of energy. As with Roadrunner, speed is only part of the Sequoia story. The other is the use of advanced technologies that help reduce costs—and will eventually trickle down to more business-oriented IT infrastructures.
