PCs and the brain: A parallel evolution

ESSEX, Vt. (AP) — It's nearly as fast as the most advanced computer, but uses a fraction of the energy. It simultaneously zaps information to thousands of points and is equipped to correct itself. It's not made of silicon and it came long before the computer chip. It is the human brain. In searching for new ways to advance computers, engineers are looking to man's gray matter for inspiration. And while comparing the two, they often wonder why a computer can't act more like a brain.

For IBM senior technologist Kerry Bernstein, the technological possibilities are astounding.

His curiosity was piqued five years ago as he chatted with a neurosurgeon at his local gym.

Martin Bednar, then head of neurosurgery research at the University of Vermont, explained to him how neurons and the brain work. In exchange Bernstein talked to him about how transistors and chips work.

"And it hit us like a freight train simultaneously that, in fact, the underlying physics is the same," Bernstein says. "So that begged the question: If the underlying physics is the same, have both systems been evolving toward the same solutions to compute problems?"

Yes, they have.

But the brain naturally had a better way.

It operates at roughly 12 kilohertz — the equivalent of 12,000 cycles per second — and burns a fraction of the power computers do, Bernstein says. That makes it exponentially more efficient than the fastest computer, he says.

"The reason is because of something that we can't do in electronics," Bernstein says. "It's this notion of massive parallelism." Meaning one bit of data can spread to 100,000 other neurons, he said.

As computers become faster, and chips become smaller, crammed with more information requiring more precision, they use more energy. That's the dilemma engineers are facing and there are very real physical limitations, Bernstein says.

"The digital paradigm has served us well. ... As we do more and more of this it's becoming onerous," he says. "What's very clear is that we cannot continue doing what we're doing. The industry cannot," he says.

Computer engineers, like Bernstein, are desperate for a new direction.

And they're confident that it's out there. Electronics is still at the steep part of its evolution, Bernstein says. It evolves much faster than humans.

Mammals add a cubic inch of brain matter every 100,000 years, Bernstein says, while processors are predicted to double in performance and capability once every 12 to 18 months.

"We cannot sustain this growth," he says.

Bernstein's first talk with Bednar led to an ongoing collaboration with neurosurgeons. Neurosurgeons came to speak at IBM and Bernstein gives a talk every year at a conference for neurosurgeons.

"It goes both ways. We've gotten a lot of inspiration from the brain already in microprocessing design," he said.

Learning how the brain works inspires more effective circuit design. It's led to quantum computing and the implantation of neurons on computer chips.

And neurosurgeons have learned how computers can improve brain surgery. Robotics, nanotechnology and imaging allow surgeons to see parts of the brain and be able to plan surgeries and how to execute them.

"About 10 years ago it became evident that computer technology is becoming a very important tool in our field so we need to see what the future of computer applications is," said Dr. Issam Awad, chair of the University of Colorado neurosurgery department.

Computer technology also might be used one day to redesign the nervous system or be deposited in a human brain.

It's already been done in rodents, said Awad, effectively creating a remote control rat.

"That would be incredible in the human brain of a stroke victim," he said. The chip could improve functioning of part of the brain that was injured and unable to send a signal.

For computer engineers, the brainstorming could lead to the generation of an electronic species, Bernstein says.

"We have a circuit now which very closely approximates the human neuron. So given the model we have for that neuron, ostensibly we can model the human brain," he says.

Some engineers think what they're seeing right now is the ascent of the early electronic species. Bernstein agrees.

"There are so many exciting possibilities," he says.

HPQ ia having indigestion with cpq acquisition and lack of 32-bit compatibility in Itanium. I don't think HPQ has the ability to digest EMC.

Does H-P Have EMC in its sights?
By MARK VEVERKA

It's high time for Las Vegas odds-makers to start handicapping technology mergers and acquisitions. With all of that loose change left over from the stock-option orgies of the bubble days, certainly techsters would be willing to lay down a few bets to see what IBM might snap up next. Or, they might be inclined to play an under-over on, say, the year-end cost-savings number from Hewlett-Packard's buyout of Compaq Computer. Why not? Now that it has been revealed that Russian mobsters are putting the fix on such allegedly pure sporting contests as the Olympic Games, who is a tech-savvy high-roller to trust?

After all, one of our favorite and most apt descriptions of the Internet-intoxicated stock market, proffered by venture capitalist Len Baker, was one of a "free-floating craps game." So, let's make gambling on tech legitimate, especially as companies begin to roll the dice on mergers, buyouts and takeovers.

After more than a year of anticipation, the consolidation season may finally be upon us as valuations -- which are still fundamentally rich -- have dramatically plummeted to levels where deals are looking much more attractive.

IBM's announcement last week that it is buying PricewaterhouseCoopers' Consulting for $3.5 billion looks flat-out cheap, compared with the $18 billion PwC was asking for its consulting unit nearly two years ago. With the IPO window narrowly open and PwC's clients fleeing in droves because the firm was also their auditor, multiple pressures were brought to bear on PwC Consulting, making the opportunity perfectly ripe for IBM's picking. (More on that later.)

And, as more companies struggle to make their quarterly numbers and Darwinian forces begin to intensify, we expect to see more marriages as the fittest companies attempt to position themselves for that day when tech-spending returns. One of the boldest handicappers is Andrew Neff, an enterprise hardware analyst with Bear Stearns in New York, who suggests there are decent odds that H-P could buy sputtering storage giant EMC.

"While this might be reaching, an acquisition of EMC by H-P could make sense from both an offensive and defensive perspective," Neff asserts.

Neff contends that such a deal would give H-P a high-end storage line it could call its own (it currently partners with Hitachi for those needs), which would also complement the well-respected storage line that H-P inherited from Compaq. As a defensive maneuver, an H-P/EMC combination could disrupt EMC's fledgling relationship with H-P's archrival, Dell Computer, says Neff. Arguing that such a deal is not far-fetched, he adds: "H-P would rather take EMC than give it up to Dell."

"We know that the two companies are talking to each other," which is more than what they were doing after their reseller partnership imploded in 1999, Neff points out. For several years, until the acrimonious split, H-P sold EMC storage hardware to its huge customer base.

Neff's speculation is fueled by a little-noticed joint announcement on July 17 by EMC and H-P that they would exchange application programming interfaces -- software platforms on which storage management systems sit. The exchange creates an open standard so the companies' products can work with one another.

"All I know is that they are a divorced couple, and they are having drinks together," Neff says. "A year ago, they only had harsh words for each other."

Another reason Hewlett-Packard might run back into the arms of EMC is that its current partner, Hitachi, is two-timing H-P with Sun Microsystems, another Hewlett rival. But, of course, like all reconciliations of this magnitude, an H-P/EMC combination is fraught with pitfalls and complications. The most obvious is that H-P is in no position to take on another major acquisition so soon after its merger with Compaq.

In addition, Dell resells EMC storage products and has struck a deal to start buying components from EMC about a year from now. Once this begins, it will be much more difficult to dislodge EMC from Dell. "It would be a lot messier a year from now than in six months," says Neff, arguing that timing would be an incentive for H-P to do a deal, even if it was still in the throes of its integration with Compaq.

Another wrinkle is that EMC appears to be forging ahead with its plan to shift from being largely a hardware maker to becoming a major developer of storage software, which generates higher margins. The Hopkinton, Mass.-based storage company reportedly is in talks to acquire San Diego-based Prisa Networks, a nascent maker of storage management software. It would be EMC's eighth acquisition since the beginning of 2000.

Prisa's software would help improve management of the lower and middle-tier storage systems that EMC sells through its partnership with Dell. Thus, again, if this deal were to materialize, it would make EMC and Dell get cozier.

For his part, hardware analyst Toni Sacconaghi of Sanford Bernstein debunks an H-P buyout of EMC, largely because he thinks the price would be too rich. EMC has a stock-market value of about $16 billion, and Sacconaghi figures that H-P would have to pay a takeover premium of about $4 billion, raising the price to $20 billion or so. That would be nearly half of H-P's own $41.97 billion valuation.

"It would be expensive and enormously dilutive because EMC hasn't been making money," Sacconaghi says. "I'm not sure why you would want to do that deal. I struggle with that notion." Also, mainly because of the price, Sacconaghi dismisses speculation that IBM will acquire EMC.

Upshot: An H-P buyout of EMC is probably a long shot. But so was an H-P merger with Compaq, which Neff recommended in a January 2001 research note. The deal was hatched nine months later. Time to place all bets
