NVIDIA teams with PGI for CUDA-x86, gifts its brand of parallelism to the world
NVIDIA's GPU Technology Conference 2010 just kicked off in San Jose, and CEO Jen-Hsun Huang has shared something interesting with us on stage -- thanks to a partnership with The Portland Group, it's bringing the CUDA parallel computing framework to x86. Previously limited to NVIDIA GPUs -- and the lynchpin of NVIDIA's argument for GPGPU computing -- CUDA applications will now run on "any computer, or any server in the world." Except those based on ARM, we suppose. Still no word on NVIDIA's x86 CPU.
UK research team brings quantum computing closer than ever... or so they say
You know the drill -- some quirky research team whips up some phenomenal discovery in the middle of nowhere, gloats about it, gets it published in a journal you've never heard of it, and then it all vanishes into the ether, leaving your soul hurt and wondering why you ever got your hopes up in the first place. The Foundations wrote a little tune about this very situation back in 1968, but a UK team from the Center for Quantum Photonics led by Jeremy O'Brien are claiming that their latest discovery is no joke. According to him, most people have believed that a functional quantum computer wouldn't be a reality for at least another score, but he's saying "with real confidence that, using [his] new technique, a quantum computer could, within five years, be performing calculations that are outside the capabilities of conventional computers." The center of this bold claim is a new photonic chip that works on light rather than traditional electricity, and those who built it say that it could "pull important information out of the biggest databases almost instantaneously." Of course, this stuff would hit the Department of Defense long before it hits your basement, but it's on you to keep tabs on the progress. Wouldn't be let down again, now would we?
IBM's Watson is really smart, will try to prove it on Jeopardy! this fall (video)
As much as we love our Google homepage, computer search remains a pretty rudimentary affair. You punch in keywords and you get only indirect answers in the form of relevant web results. IBM doesn't seem to be too happy with this situation and has been working for the past three years on perfecting its Watson supercomputer: an array of server racks that's been endowed with linguistic algorithms allowing it to not only recognize oddly phrased or implicative questions, but to answer them in kind, with direct and accurate responses. Stuffed with encyclopedic knowledge of the world around it, it answers on the basis of information stored within its data banks, though obviously you won't be able to tap into it any time soon for help with your homework. The latest word is that Watson's lab tests have impressed the producers of Jeopardy! enough to have the bot participate in a televised episode of the show. That could happen as early as this fall, which fits right in line with our scheduled doom at robots' hands by the end of 2012. Ah well, might as well get our popcorn and enjoy the show.
NVIDIA VP says 'Moore's law is dead'
NVIDIA and Intel haven't been shy about their differing respective visions of the future of computing in the past year or so, but it looks like Team GPU just upped the rhetoric a little -- a Forbes column by NVIDIA VP Bill Dally argues that "Moore's law is dead." Given that Moore's law is arguably the foundation of Intel's entire business, such a statement is a huge shot across the bow; though other companies like AMD are guided by the doctrine, Intel's relentless pursuit of Gordon Moore's vision has become a focal point and rallying cry for the world's largest chipmaker. So what's Dally's solution to the death of Moore's law? For everyone to buy into parallel computing, where -- surprise, surprise -- NVIDIA's GPUs thrive. Dally says that dual, quad- and hex-core solutions are inefficient -- he likens multi-core chips to "trying to build an airplane by putting wings on a train," and says that only ground-up parallel solutions designed for energy efficiency will bring back the golden age of doubling performance every two years. That sounds fantastic, but as far as power consumption is concerned, well, perhaps NVIDIA had best lead by example.
Physicists calculate the end of Moore's Law, clearly don't believe in Moore's Law
If you're looking for pundits with an end date for Moore's Law, you don't have to look far. You also don't have to look far to find a gaggle of loonies who just knew the world was ending in Y2K, so make of that what you will. The latest duo looking to call the demise of the processor mantra that has held true for two score comes from Boston University, with physicists Lev Levitin and Tommaso Toffoli asserting that a quantum limit would be achieved in around 75 to 80 years. Scott Aaronson, an attention-getter at MIT, expects that very same limit to be hit in just 20 years. Of course, there's plenty of technobabble to explain the what's and how's behind all this, but considering that the brainiacs of the world can't even agree with Gordon Moore's own doomsday date, we're choosing to plug our ears and keep on believin' for now.

Inc.com: iPhone is "next major computing device"
Zach Nelson at Inc.com has seen the future of computing, and it is the iPhone. He writes:"Some people use it to play music. Others marvel at the photo-browsing interface, and some of its users just want to look cool. I don't care about any of those things when I look at the iPhone. What I see is the breakout of the next major enterprise computing platform."This is basically what I said after my first full day with the iPhone. It's a portable computer that just happens to make phone calls, not a phone that performs a few tricks. Months later, my feelings haven't changed. I use it primarily as a computer (and an iPod) and occasionally as a phone. In fact, when I'm showing it off to people, the phone features (making calls, working with contacts, etc.) are what they're least interested in. Email and the internet are always first.With that in mind, I'll share my ten favorite iPhone-optimized web sites. meebo. Nice AIM implementation. No frills, just function. PocketTweets. Until we get Twitterrific for the iPhone, I'll use PocketTweets. It looks nice and works. Leaflets. A portal for several useful iPhone-optimized pages. I especially like their Newsvine, Flickr and Major League Baseball implementation. JiWire. Quickly find public Wi-Fi in your neighborhood. Tomatometer. Find reviews on nearly any movie. MoviesApp. Somehow, pulling up movie times on an iPhone impresses people more than anything else. PopTakeout. Browse top headlines from Digg, Newsvine, Delicious, more. Plus, the Chinese takeout box icon is cute. MyPhoneFootball.com. No frills, just speedy updates on NFL scores and standings. Fumbleview. Real-time, java-powered play-by-play on your favorite NFL games plus chat. I love it. Weather Underground humiliates the iPhone weather widget.
Popular Science on gaming's hardest technical problems
It only takes a quick, comparative glance at Pong and BioShock to see how far gaming technology has coming in a relatively short time. But despite all the progress, we haven't quite reached the pinnacle of a real-time, controllable, photo-realistic environments quite yet. What's stopping us? Popular Science takes a look with a recent piece on the ten greatest challenges in making realistic games.The photo essay looks at some neat cutting edge technology aimed at fixing virtual modeling problems both natural (water and fire are particularly nasty to model) and human (artificial intelligence and uncanny valley faces, for instance), but the technology that impressed us most is based firmly in the real world. Organic Motion's Stage system replaces the standard black-with-ping-pong-balls motion capture suit with a simpler system. "Subjects step in front of the camera in their street clothes, and instantly their avatar forms onscreen," reads Pop Sci's description of what sounds to us like the coolest thing ever.So will we ever reach that holy grail of totally reality simulation? It's a possibility if Moore's Law keeps up, but there'll almost certainly always be something to improve. As one designer put it to the magazine, "the more we can do, the more excited we get, and the more we want to do." In other words, the reach will always exceed the grasp.[Thanks Wonderflex]
University of Edinburgh crafts energy efficient FPGA supercomputer
Considering that ATI and NVIDIA don't seem to be making any substantial strides in reducing the amount of energy required to run their products, it's a tad surprising to hear of an entire supercomputer running a bit leaner than the competition. Hoping on the ever-growing green bandwagon, University of Edinburgh developers are at it again, this time crafting an uber-speedy machine that's reportedly "ten times more energy efficient and up to 300 times faster than its traditional equivalents." Based on field programmable gate arrays (FPGA), the chips are not only very difficult to program, but they can currently only be used "to perform very specific tasks." Of course, the creators are more interested in the extreme number crunching and power saving abilities than anything else, and while no commercial uses have been identified just yet, the machines could purportedly be used in fields such as "drug design, defense and seismology."[Via CNET]
NASA backs quantum computing demonstration
NASA has confirmed that it built a quantum computer under contract for Canadian startup company D-Wave Systems Inc. after D-Wave was accused of faking a recent demonstration to businesses and academia. During a demonstration last month, the company revealed that its 16 qubit (more qubits = more processes) quantum processor had been left back at the company's offices, and therefore the test would be show via an internet link. According to D-Wave CEO Ed Martin, "businesses aren't too fascinated about the details of quantum mechanics": unfortunately, a group of industry experts were interested, and they made their skepticism clear. The result is NASA's confirmation that it did in fact construct D-Wave's quantum processor design under contract; a confirmation that most people will be inclined to accept. The underlying technology shown in the demonstration was the use of a normal digital processor in conjunction with a quantum chip, which D-Wave hopes will enable commercial applications of quantum computing. D-Wave is planning to up its design from 16 qubits to 1,024 qubits by the end of 2008, a rather controversial aim for some that think practical quantum computing is still up to a decade away. There's gotta be something about quantum computing that puts scientists on edge: perhaps it's the platform's potential to make all current forms of encryption obsolete ...[Via Slashdot]
ACCS GRAViTONUS gives quadriplegics tongue-controlled computer interface
While other forms of alternative computing are certainly available, yet another group of researchers are touting their own rendition as a radical new way for quadriplegics to engage in computerized learning and entertainment. Dubbed the Alternative Computer Control System (ACCS) GRAViTONUS, the proposed hands-free system would enable folks who have suffered spinal cord injuries or other forms of paralysis to dictate basic computer functions entirely with their tongue. The prototype looks to be quite non-invasive, and when worn around one's head, can enable users to mouse around and navigate within applications by way of a precise tongue-controllable interface. Interestingly, it's even stated that the device won't hinder one's ability to drink, speak, or breathe, but we assume you'd have to give the mouthpiece a good washing after every use to avoid bacterial buildup. Nevertheless, the ACCS GRAViTONUS backers are now scouting VCs who'd like to get this creation to market, so if you've been looking for something intriguing to get wrapped up in, give these blokes a ring.
Microsoft exec avoids confirming Vista release
We should start off by saying that this could be nothing but cautionary corporate-speak, but rather than confirming the scheduled January ship date for Windows Vista -- which is what everyone at the company's annual analyst meeting wanted to hear -- Microsoft exec Kevin Johnson seemingly opened up the door to fresh delay rumors by telling attendees that the beleaguered OS will be released "when it is available." Johnson's comments came as a response to analysts who wanted to know if Vista was still on track for a January release; instead of a simple "yes," however, he told the group that "we are going to ship the product when it is ready, and we are going to take it milestone by milestone." Now, what sounds like a non-denial of further delays could simply be part of a new policy to avoid making specific promises, but following Bill Gates's recent "statistical analysis" that Vista is only 80% likely to ship in January, this development is troubling to say the least. At this point we don't really know what to expect anymore, and since our current XP-powered setup already does everything we need it to, we're getting pretty close to not caring if Vista is ever released at all.
Computer-brain interface device will speed up video footage review
No matter how many spy cams and unmanned surveillance drones government and law enforcement officials can pack into public spaces, their utility has traditionally been limited by the finite amount of footage human monitors can review in a given time frame. New DARPA-sponsored research out of Columbia University, however, may soon allow folks tasked with keeping an eye on video feeds to perform their jobs up to ten times faster -- by leveraging the rapid image processing abilities of cortical vision. Since people are able to recognize suspicious activity much more quickly than they can consciously identify what's wrong, professor Paul Sajda and his team developed a computer-brain interface device -- similar to ones we've seen control an on-screen cursor and bionic limb -- that monitors an operator's neural output while he/she is watching streaming footage, and tags specific images for later perusal. Once the technology is perfected in the coming months (it still emits too many false positives, apparently), it could allow for more thinly-staffed monitoring departments, though we suspect it will probably just convince officials to deploy more and more cameras.
Vista forecast: 20% chance of delays
If you're one of the many folks eagerly awaiting the January release of Windows Vista, then there's a small-but-not-insignificant chance that you may be in for a letdown -- a 20% chance, actually, according to outgoing Microsoft CTO, lifelong Engadget reader, and occasional video pirate Bill Gates. During a presentation in Cape Town, South Africa, Mr. Gates informed his audience that although there's an 80% probability that the next-gen OS will ship as scheduled, "we've got to get this absolutely right," and stressed that "if the feedback from the beta tests shows it is not ready for prime time, I'd be glad to delay it." Now, we can't imagine that anyone would want to purchase buggy software, so it's reassuring to see that Microsoft is committed to only pushing a polished product out the door, but we have to say that Gates' choice of words here makes him come across as just a little cavalier. Because if he's "glad" to continue frustrating us with these tragi-comic delays, then there's probably quite a few people out there who will be just as glad to stick with their copies of XP out of spite -- or even worse, make the dreaded leap over to Leopard or Linux.[Thanks, Matt and Oliver O.]
Dude, your Dell is on fire

IBM, GIT overclock chip to 500GHz
If you were wowed by those Japanese modders who overclocked their stock CPU to 7GHz, wait till you hear about IBM's latest foray into the world of ultra-fast computing: together with researchers from the digital camera-hating Georgia Institute of Technology, Big Blue has managed to overclock a chip to an unheard of 500GHz. Granted, the model they used already had a blistering native clock speed of 350GHz to begin with, but we're still floored that you could actually coax a small silicon wafer into operating at an incredible half-terahertz. As you probably suspected, there's no way to achieve speeds like this at room temperature, so the team froze their high-performance silicon-germanium chip to a super-chilly negative 451-degrees Fahrenheit, which is just eight degrees above absolute zero. Unfortunately, after learning about this breakthrough, electronics giant Sony apparently felt that consumers would no longer be impressed with their much-hyped Cell processor, so they've once again delayed the PS3 until IBM can make the liquid helium-cooled CPUs suitable for mass production . Expect the 500GHz PS3 to hit stores sometime in 2011.[Thanks, bento-san]
Vista Premium logo requirements: no hybrid HDDs after all?
Ken Fisher over at Ars Technica has done us all a good turn and pored over the latest version of the mind-numbingly boring Windows Vista Logo Program Device Requirements documentation, summing up the key features that consumers can expect to see from machines sporting the Vista Premium logo. Effective immediately, PCs wishing to display the coveted sticker must rock only USB 2.0 ports, at least one digital output for all add-in video adapters, 100Mb Ethernet and/or WiFi (which must be of the 802.11g flavor), and HD audio quality that passes some kind of "high-fidelity audio experience test," with other requirements concerning Serial ATA drives, HDCP compliance, HD playback, and support for bootable USB drives going into effect on June 1, 2007. Also noteworthy in Fisher's analysis is his claim that hybrid hard drives will not in fact be necessary for laptops to flash the Premium logo, as previously reported by TG Daily based on a conversation with Microsoft at TechEd. Instead, Fisher argues that the so-called "Storage Requirement 0005" in question is only a list of technical standards that need to be met by hybrid HDDs should manufacturers choose to include them in their devices, which makes sense after considering how unlikely it is that Redmond would force such a new and unproven technology down people's throats.Read- Vista Premium logo requirements [Via Slashdot]Read- Hybrid HDDs not required after all
Averatec's 10.6-inch AV1150 ultra-portable notebook
Averatec has just released the first member of its new 1100 series of ultra-portable notebooks, the AV1150-EW1, which sports the same low voltage Pentium M chip that we saw last year in the company's 1000 series, but improves on several other key specs. The most notable difference between the two series is the inclusion of a DVD burner on the new model, although doubling the RAM from 512MB to 1GB is certainly a much appreciated bump as well. All the rest of the features -- 80GB HDD, integrated graphics, WXGA display, and 802.11b/g -- remain the same, and yet Averatec has still managed to shave off a few ounces to help the 1150 weigh in at just 3.4 pounds. Available immediately online or in select stores, we found this model selling for a wallet-friendly $1,300, which is a bit less than the AV1050 commanded at its debut.[Via The Gadgets Weblog]
Logitech's Cordless Desktop S 530 Laser for Mac
Don't worry, Mac fans, Logitech hasn't forgotten about you -- you're just not as important as the rest of your friends who use a Windows box. In fact, just to show you Apple diehards a little extra love, the company has released a version of the Cordless Desktop S 510 that features all your favorite Mac-specific keys and application shortcuts, and manages to one-up the Windows model by swapping out the optical mouse for a laser one. Other than an improved pointing device, though, the Cordless Desktop S 530 Laser for Mac rocks the same basic feature set as the S 510 -- media controls, slim/ergonomic design, and both desktop and laptop USB transmitters -- except you don't get the option of paying an extra twenty bucks to step up to a model with a bundled remote. Instead, that twenty will go towards the high-precision laser inside the mouse, because the Mac set costs the same $100 as the remote-sporting, but laser-less, Windows package.[Via InputReview]
Gigabyte's A963 and H971 VIIV-powered HTPCs
Besides that pair of smartphones we spotted earlier today, Gigabyte has also been showing off a set of home theater PCs at Computex, and whether you like your media centers in tower or pizza box configuration, Gigabyte's got you covered. While both the silver H971 and white A963 support VIIV-powered Core Duo processors, the rest of the specs are nothing that will get you too excited, and the lack of built-in HDMI or WiFi will probably keep most of our readers from even giving these machines a second glance. Still, if the Intel spin machine has done its job right, the VIIV stickers alone should help Gigabyte move a few units whenever they hit stores.Read- A963 [Via AVing]Read- H971 [Via AVing]
