Hasta La Gadget!

For all the money and effort poured into supercomputers, their lifespans can be brutally short. See IBM’s Roadrunner as a textbook example: the 116,640-core cluster was smashing records just five years ago, and yet it’s already considered so behind the times that Los Alamos National Laboratory is taking it out of action today. Don’t mourn too much for the one-time legend, however. The blend of Opteron and Cell processors proved instrumental to understanding energy flow in weapons while also advancing the studies of HIV, nanowires and the known universe. Roadrunner should even be useful in its last gasps, as researchers will have a month to experiment with the system’s data routing and OS memory compression before it’s dismantled in earnest. It’s true that the supercomputer has been eclipsed by cheaper, faster or greener competitors, including its reborn Cray arch-nemesis — but there’s no question that we’ll have learned from Roadrunner’s brief moment in the spotlight.

IBM is worried that we’re reaching the end of the road for CMOS technology — that we need new materials beyond silicon to keep the power draw down in chips as their performance goes up. It may keep future circuitry extra-lean through a new technique that puts a metal oxide in silicon’s place and allows for non-volatile processors and memory. By running ionized liquid electrolytes in currents through the oxide, the company can switch that oxide from an insulator to a conductor (and vice versa) that can reliably maintain its state, even when there’s no power. The trick would let a logic gate or switch kick into action only when there’s an event, rather than needing constant jolts of electricity — and without the pressure or temperature changes that had ruled out metal oxides for chips in the past. We’re still far from replacing silicon with more efficient oxides given the early state of IBM’s work, but having a consistent method is an important first step.

Super computer Watson can crush puny humans at Jeopardy. It can do a pretty bang-up job as a doctor. It can swear up a storm. Two of those aren’t easy for a normal person, but that’s not enough for IBM. IBM wants more. And part of it’s plan to push Watson to its limits should really get things cooking. Literally. More »

We heard almost a year ago that Memorial Sloan-Kettering Cancer Center had turned to IBM’s Watson as a tool to help doctors provide the best cancer treatment recommendations, and it looks like those plans are now starting to be put into practice. IBM, along with WellPoint, Inc. and Memorial Sloan-Kettering, have today announced what they describe as the “first commercially developed Watson-based cognitive computing breakthroughs.” More specifically, they’ve developed a system that allows Waston to draw on a wealth of medical information and quickly provide evidence-based treatment recommendations to doctors.

And we do mean a wealth of information; as IBM explains, Watson has spent the last year digesting more than 600,000 pieces of medical evidence and two million pages of text from 42 medical journals, and it has the ability to parse some 1.5 million patient records covering decades of cancer treatment history. That all takes the form of two separate “Watson-based” products to start with, one of which IBM expects to be used by more 1,600 providers by the end of this year. You can find more details on those at the source links, and get a more general overview of the project in the video after the break from IBM.

You’ve hear about Watson, IBM’s own child and artificial intelligence system that has been touted for its super-computing powers. Well, Watson might know a lot of stuff, defeated “Jeopardy!” champions, and memorized the Urban dictionary, but it still needs to go to school. IBM has announced that it will be sending Watson to New York State’s Rensselaer Polytechnic Institute. Although that sounds weird, but yes, Watson is the first computer to be sent to university. Watson will be learning courses in math and English. (more…)
