Nvidia Builds A Dream Machine

February 9th, 2012

Steve Scott wants to build a supercomputer that can calculate 1 quintillion floating-point operations per ­second. That’s a one followed by 18 ­zeroes or, in computer speak, an exaflop. Such a machine would be a billion times faster than a MacBook Air and could design wildly efficient ­combustion engines, simulate the workings of an entire cell and model a clean-burning fusion reactor. With enough zeroes Steve Scott can change the world.

The reason no one has built an exa­scale computer yet is the electric bill. An exaflop machine using today’s standard x86 processors would draw 2 gigawatts of electricity, the maximum output of the Hoover Dam. The biggest supercomputer ever built handles 11 quadrillion flops (or petaflops, a 1 with 15 zeroes) and draws 13 megawatts, the juice of nine wind turbines. Scott, one of the world’s leading supercomputing engineers, sees a day coming when we can have computers a thousand times faster than that, without using that much more power.

The prospect has brought Scott, 45, to Nvidia ( NVDA – news – people ), the Santa Clara,Calif. company that is the world’s largest maker of graphics-processing units, or GPUs. Its incredibly complex circuit boards are prized by videogamers for their ability to render battlefield chaos and oozing zombies with stunning realism. Nvidia chips are also prized by the supercomputer community because they can handle six to eight times more operations per unit of energy than an Intel ( INTC – news – people ) chip. Lash together thousands of them and you get a power-sipping supercomputer.

Scott’s last job was as chief technology officer of supercomputer manufacturer Cray ( CRAY – news – people ). In the spring of 2009 Intel pulled out of a joint effort to build ­supercomputer processors with Cray. “I was definitely disappointed,” says Scott, but he doesn’t blame Intel. “The high-performance computing market just isn’t big enough to support the development of competitive processors.”

It’s a humbling admission for Scott, a 19-year veteran of Cray with a Ph.D. in computer architecture from the University of Wisconsin and 27 patents to his name. “Scott is at one of those interesting intersections,” Nvidia Chief Executive Jen-Hsun Huang says. “As a computer architect he’s a geek at heart, and yet he really lives to ­understand customers and markets.”

Supercomputers are a little more than a third of the $8.6 billion market for ­high-performance computers, ­according to IDC, but they are a-fast-growing and highly profitable slice that confers great p.r. to hardware makers. Sales overall of high-performance computers will rise 56% to $13.4 billion in the next three years, according to IDC. While Nvidia doesn’t break out numbers for its supercomputer business, its overall professional solutions group is its most profitable, boasting 36.7% gross margins for the first nine months of 2011, compared to 21.1% for Nvidia’s GPU business.

Nvidia can keep growing in supercomputers by exploiting its energy-­efficient edge. Its chips have dozens of simple cores that tackle lots of repetitive computations at once. Supercomputer scientists have been pushing the idea of parallel computing for years. It’s more power-efficient than an Intel Core i5, which is built around two to four quick, versatile cores that compute one instruction at a time. Pairing Intel or AMD chips with Nvidia’s graphics chips in supercomputers (much as they are in personal computers) results in machines that are three times more efficient than ones that rely on CPUs alone.

Three of the world’s five fastest super­computers use Nvidia’s processors. In October the Oak Ridge National Laboratory announced an effort to build the world’s fastest supercomputer, which will use AMD Opteron chips and 18,000 of Nvidia’s graphics-processing units. When it is completed later this year, it might crank out up to 30 petaflops and use around 10 megawatts.

The Department of Energy has ­announced it would like a machine that can hit exascale speeds using just 20 megawatts of power. The same technology could be used to build machines able to do the work of today’s supercomputers on a much smaller power budget. “That would allow a small ­engineering group to do things that today can only be done by a rarefied few,” says Scott. He thinks we can hit that mark by the end of the

The Rise of the Thinking Machine

August 26th, 2011

This year has seen some notable advancements in computer-based brain mimicry, not just on the artificial intelligence (AI) front, but also related to in silico brain simulations.

Watson’s vanquishing of Jeopardy champions Brad Rutter and Ken Jennings in February set the stage for the year. The now world-famous IBM super exhibited a sophisticated understanding of language semantics along with the ability to integrate that understanding into a complex analytics engine. Since the Jeopardy match, IBM has been looking to take the technology into the commercial realm, most notably in the health care arena.

Meanwhile projects like FACETS (Fast Analog Computing with Emergent Transient States) and SpiNNaker are working to uncover the nature of the brain at the level of the neuron. The goal here is not to create any kind of artificial intelligence system a la Watson, but rather to simulate the neuronal network of the brain for basic science research.

SpiNNaker, a multi-year project run out of the UK at the University of Manchester, also is attempting to map the brain’s low-level biological structure and function. In June, the project received its first batch of custom-built ARM processors that will eventually power a 50 thousand-node neural network supercomputer.

The FACETS project, managed by the University of Heidelberg, actually wrapped up last year. It’s sequel, BrainScaleS project booted up in January 2011, with the idea of developing of a “brain-inspired computer architecture” based on a custom-designed neural network hardware. BrainScaleS has links to Henry Markram’s famous Blue Brain work.

Blue Brain, based at the École Polytechnique Fédérale in Lausanne (EPFL), is perhaps the best-known of the brain mimicry projects. The idea is to perform detailed simulations of the brain at the scale of the neuronal network. In this case though, the work was done with conventional supercomputing hardware (if you can call Blue Gene conventional). The project has successfully simulated a rat cortical column.

The follow-on to Blue Brain, also headed by Markram, is the Human Brain Project. The goal here is to move from rats to human and simulate the entire brain.

The other bookend to the Watson AI story is also from IBM. Last week, the company unveiled their cognitive computing chips. This is basic research as well, but IBM is aiming the technology at developing thinking machines, rather than just using it to elucidate the workings of the brain.

I queried Markram about the significance to IBM’s latest chippery, who responded thusly: “This is a very important technology step. There are still many challenges ahead, but neuromorphic chips like IBM’s are bound to become key processing units in hybrid architectures of future computers.” He also recognized the work at FACETS/BrainScaleS and SpiNNaker as contributing to this growing body of knowledge.

So what does it all mean? For those of you who read about such development in the popular press, there has been plenty of speculation about the future of artificial brains. A lot of this is centered around how such technology will impact the human condition, particular how intelligent computers will displace human labor.

The big question is if such technology will ultimately benefit people or merely make them superfluous. Edward Tenner, a historian of technology and culture with a Ph.d in European history, believes it will be the former. From a piece he penned in The Atlantic:

Will people be obsolete? I doubt it. The economic theory of comparative advantage explains why. Assuming there will still be people, even if the computers are running everything, it will pay for them to let people do what they are relatively better at. There’s likely to be a higher opportunity cost for computers to do more intuitive analysis for which human brain-body system has evolved and concentrate on tasks at which their abilities are an even high-multiple than people’s. In the case of computers and people, as I suggested about IBM’s Watson and Jeopardy! there will always be elements of tacit knowledge and common sense that will be extremely expensive to achieve electronically.

His premise is that it will always be cheaper and more effective to have a real live human provide answers that involve intuition. “So even if, for example, computers surpass physicians on diagnostic reasoning,” he writes, “it will be cheaper, more effective, and safer to have their judgment double-checked by a real doctor.

Maybe. But I think one of the article’s commenters nailed it pretty well when he suggests that the real question is not whether computers will replace all labor, but how many jobs will be displaced by intelligent machines and how that impacts our traditional economic model. He writes:

In classical economics, employers furnish the capital, and workers produce raw materials and finished goods or services. There is tension between worker and management: both need each other, but both want a bigger piece of the profits from work; each has a strong bargaining position, and the compromise they reach determines wages and benefits. But what’s playing out on the world stage isn’t classical economics at all. With every passing year, owners of capital are relying less on workers and more on machines. The balance has shifted in favor of owners of capital.

We don’t have to wait for the future to see this play out. It’s been happening for decades, as businesses large and small have adopted IT. The commenter notes that multinational tech manufacture Foxconn will be shedding a million of its million and half workers manufacturing circuit boards over the next two years, thanks to assembly line robotics.

We’ve certainly seen similar downsizing across the manufacturing sector in general. A century ago, the same process happened in agriculture, a sector whose labor base continues to decline. It’s not that the industries are shrinking, just their labor force.

With the introduction of more sophisticated computing, machines are moving higher up the food chain. For example, over the last three decades at JP Morgan, profitability has risen by a factor of 30, but employee head count has only doubled. That’s directly attributable to computer technology raising productivity.

The advent of really intelligent machines like Watson and its neuromorphic brethren will accelerate all this, in ways we can only imagine. Even industries that are enjoying relatively rapid job growth today, like professional services, education, and health care, will eventually be impacted.

From my perspective, the key problem is that our social and economic systems are not ready for this. While everyone is fixated on globalization, I think that’s a side show compared to what will happen — and is happening — as intelligent technology displaces human labor worldwide.

It’s not just that people who have invested years of specialized training will find their jobs threatened. As the commenter noted above, the balance between capital and labor is shifting rapidly in favor of capital as the labor force is squeezed into fewer and fewer jobs that resist automation. The hope is that other industries will emerge to engage the masses again, as happened after the agricultural and industrial revolutions. But this time may be different.

Desktop PCs: Dead as a doornail, or maybe just a fax machine

June 27th, 2011

The corporate desktop has looked the same for decades: computer, keyboard, mouse, desk phone, maybe a printer. But do these tools dominate because they’re the perfect combination of technology needed for work today, or is the enterprise workplace due for an extreme makeover?
Death of the mouse
According to industry analysts, hardware vendors, architects and futurists, the odds that major changes will revamp the standard corporate cubicle, technology tools and even buildings, rise every day.
Of course, fundamental changes like this don’t happen at all once. “When you’ve got hardware in place, it’s tough to yank it out,” cautions Rob Enderle, principal analyst for the Enderle Group. “Some corporate PBXs are still in use from the 1980s. Faxing was declared dead in 1995, but I have two in my office.”
Enderle’s point is that it takes a major event to upset the status quo, but that event, or confluence of events, appears to be happening today.
The proliferation of mobile devices, the broad availability of high-speedwireless access, cloud-based services and browser-based videoconferencing mean that employees no long have to be tied to their desktop PCs.
Unplanned obsolesence
“The desktop computer really will become obsolete,” says Amy H. Tabor, director of facilities planning for RNL, a global, full-service design firm. “This change is driven by the way we work, the need for more flexibility and space use, and the younger generation expecting the difference.”
Because employees are on the move, a single desktop computer in every cubicle is no longer enough. “What was once a single device computer system is now a two- or three-device environment,” says Jeff Tripp, a Technology Strategist for Enterprise Clients at Intel. The extra devices are laptops, smartphones and tablets.
“It will be interesting to see if the ‘desktop’ term ever goes away,” says Tripp, who works with enterprise Intel customers, and focuses five years in the future. “Younger kids tend to start with mobile laptops or tablets in kindergarten.”
RNL, along with Steelcase and OfficeScapes, is sponsoring Workplace-2020, a digital forum to “explore workplace trends, spark discussion, and inspire debate regarding the workspace of the future.” Ten years ago, RNL spearheaded Workplace-2010, and built out 6,000 square feet of office space to show off new concepts and provide a place for continued research.
“The technical change is now exponential, faster than ever before,” says Tabor, “and will continue to evolve the technology we know. But maybe not as much as the sea change with the arrival of mobile devices and smartphones.”
The Empty Cubicle Syndrome
Now that employees are mobile, changes are occurring both inside and outside the traditional cubicle. Jenny Englert, senior cognitive engineer at Xerox, launched a study on the future of work in 2008. In 2009, she focused on mobile workers and the technologies to support them.
“We see new work styles, and even people with their own cube or office are always out at meetings and the like,” Englert says. “I’m at my desk only about 20% of the time.” Her group followed work practices, rather than technology, and found that as work has become mobile, technology must support that mobility.

Architects are taking notice of empty cubicles, says RNL’s Tabor. “There’s more emphasis on building collaboration space. Companies are giving up individual space for team space.”
Daniel Burrus, business strategist and technology futurist, is also the author of the new book “Flash Foresight: How to See the Invisible and Do the Impossible”, a New York Timeshardcover bestseller.
“The workplace is changing dramatically, and the tipping point is now,” Burrus says. “In 2010 more non-Windows machines, like tablets, iPhones and other devices, than Windows computers were plugged into the Internet. Smartphones outsold laptops and PCs.”
Burrus says that increasingly the computer of choice is a smartphone or a tablet. “We will see enterprise level apps for services workers, sales, maintenance. It’s a form factor that’s incredibly powerful.”
Chuck Wilsker, head of the Telework Coalition, says we all are already teleworkers, but we may not know it. “I spoke recently to a group of 260 businesspeople. I asked how many were teleworkers, and only about 10% raised their hands. Then I asked how many worked only at their primary place of employment and never from home or the road. Only two people raised their hands. The reality today is that almost every knowledge worker is now a teleworker.”
In her research for Xerox, Englert found that mobile workers were outside the office about 80% of their workday. They tried to print what they needed before they left, but that didn’t always work. Xerox then introduced a mobile enterprise printer that supports output from a mobile phone.
The video void
On the flip side, employees who regularly work at home can feel isolated. The obvious answer is videoconferencing, but personal videoconferencing has been slow to catch on.
“The big problem with personal videoconferencing is companies bring products to market that don’t work with other products,” says analyst Enderle. “I’ve been working on those projects since the mid 1980s, and they just don’t work together.”
“There are dozens of videoconferencing systems out there now, and have been for years,” Wilsker adds. “We will get to interoperability one of these days between phones, and get used to using video. Young people are driving this. I met a 28 year old man from Turkey, and he uses Skype on his laptop to get cooking lessons from his mother, who’s still in Ankara.”
Lucky for the cooking student, his mother isn’t scared of the camera, but many still are. “The biggest problem with videoconferencing for some companies is that some people are self-conscious about being on camera,” Wilsker says.
Judging by the number of young people in YouTube videos, future workers won’t have that problem. Add in the fact that Apple now provides cameras in front and back of the new iPads and iPhones, and an audio-only conversation may be rare in a few years.
Or you may log in and control a personal telepresence robot to move around the office and talk to people through the speaker and video screen on the robot. Anybots now has these for sale.
Plus, Avaya and others offer browser-based immersive environments for corporatecollaboration.
The evolving office
No matter how quickly videoconferencing becomes mainstream, Tabor at RNL says employees have reasons to be in an office with other employees even if they often work anywhere. “Companies will have technology that users can’t afford, so it will be centralized. Offices provide sociability, and maintain the company’s brand and identity. There’s still a need for office space.
Companies must now support four and five generations of workers, Tabor says, in one workspace, because Baby Boomers plan to work longer than previous generations. “Each will have a different set of expectations and demands, and there will be some accommodation of generational preferences. But younger people will drive the innovation, and the most successful older folks will be those who adapt to the newer way of doing things.”
“One huge change for the future will come as we leverage Moore’s Law and move processing to the cloud,” Burrus says. “Watch that jump ahead as you can use a smartphone to access super computer capabilities in the cloud. How about having IBM’s Watson in your smartphone?”
No matter what’s in the cloud, how devices access that cloud will change soon. Rich Cheston, executive director and distinguished engineer for Lenovo, says, “It’s shortsighted to view every endpoint as just a piece of gorilla glass. IT people want better security.”
Cheston says Lenovo has developed technology that leverages the capabilities of the endpoint by introducing a way for cloud applications to interrogate clients and treat them differently. Need better security? If your laptop has a fingerprint reader, the cloud app can demand two-factor authentication, then tailor your access based on your increased security clearance. If the cloud application can tell if a laptop has a camera, it can automatically provide a videoconference option.
And your future office will leverage new tools to share information between devices. “My devices should know when I walk into a conference room, and that I have a conference scheduled at the time,” says Intel’s Tripp. “It should prepare an embedded projector in the room, and make the video connection, etc. This will be leaps and bounds forward. And if my phone has a GPS but my laptop doesn’t, they should share information between them.”
Englert at Xerox works with the Rochester Institute of Technology in her research. Students ask “Why can’t your wall become your workspace,” she says. “Walk into a room, and it will customize to you. Tools will become gesture based, not touch. Just look at a software tool, and it will automatically show up. But it’s been interesting to see from the young people they wanted face to face interaction.”
Intel’s Tripp agrees. “It’s hard to beat people in one room with a whiteboard for brainstorming with our current technology. Tech is getting there, and smart boards help, but there’s value in the daily interactions people have. Hard to replicate walking into a room and working together.”

Time machine

April 1st, 2010

Turn your computer into a time machine! Make your Vista or Windows 7 show pictures like good old fashioned Windows XP. Update your device drivers, but be ready to roll back to the originals. Listen to hard-boiled detective shows from the 1940’s and ‘50’s on your computer.

Make Vista and Windows 7 display thumbnails instead of icons

Thumbnails are small pictures of the larger pictures on your computer.

When I moved from XP to Vista, I could not for the life of me figure out why I could only ever see an icon instead of thumbnails in my Pictures folder. I hate that. I just want things to be the same as they were in the last century!

As luck would have it, there’s a way to make Vista and Windows 7 behave just like XP when it comes to thumbnails.

Click on Start
In the Start Search box, type Folder
Select Folder Options from the result at the top of that window
Click on View
In the Files and Folders section, clear the check box for Always show icons, never thumbnails
OK your way out

Now you can see what your pictures look like without having to open each one.

Find new drivers and keep the old ones, just in case

Drivers are the software that makes your hardware work. Your printer, network card, video card, and all your hardware need drivers. When the drivers work well, you don’t even know they’re there. When they don’t work, neither does your hardware!

Manufacturers of computer equipment release updated drivers from time to time. Sometimes that new driver adds more capabilities than the old one. Sometimes the new one fixes a problem with a previous release. If your video card is acting weird, if your network connection keeps dropping for no apparent reason, if your printer suddenly starts printing gibberish, you might want to update the driver.

One school of thought is that all drivers should be totally up to date all the time. Another says, “If it ain’t broke, don’t fix it.” No matter which one you subscribe to, you’ll need to update a driver at some point. And the first thing you learn is that finding what driver you have and finding what driver you need can be a real chore.

If the idea of going from website to website looking for drivers doesn’t appeal to you, you might be interested in Device Doctor. It’s a free program that scans your computer hardware and checks to see if there are new driver updates available for your devices. When it finds them, it gives you a button to click on to download the updates. This could not be any easier. You can download it here: Device Doctor

Two things to remember: First, don’t go crazy and update all your drivers at once. If something goes wrong, you’ll need to have a pretty good idea which driver caused the problem so you can reverse the process.

Second, it’s good to have a backup of ALL your drivers, not only the ones you’re updating. I like a free program called Double Driver for this. It’s available here: Double Driver

Having all your drivers backed up in one place makes it easy to travel back in time to where your hardware was functioning properly.

Although these tools are excellent, they are for experienced computer users. If you are over your head on a driver update, don’t hesitate to call in a professional.

Turn your computer into a 1940’s radio

The final time travel tip is a website called Audio Noir. Point your browser to Audio Noir and listen to an audio stream of detective radio shows from the 1940’s and 1950’s. Richard Diamond, Yours Truly Johnny Dollar, Sam Spade, Dragnet, and more radio cops and private eyes are available 24 hours a day. You can listen with iTunes, WinAmp, Windows Media Player, RealPlayer, of VLC Player. If you’re not old enough to remember these shows, you can check them out and see what your grandparents did in the old days, before you made them join Facebook.

Do you need help with your computer? I’m here to help you and your home or business computer get along!
