IBM guru questions computers

[ Johannesburg, 4 August 2008 ] - Mark Dean, one of the inventors of the personal computer (PC), is questioning the relevance of the device in crossing the digital divide.

Dean, currently VP for research at IBM, was instrumental in the recent donation of a Blue Gene supercomputer to the Centre for High Performance Computing, part of the Council for Scientific and Industrial Research's Meraka Institute.

Dean says the debate over low-cost PCs overlooks a “more important question: Is the personal computer the right device for bridging the digital divide?”

“As leader of the engineering team that developed the core technologies still in use in more than 90% of the world's personal computers, I feel confident that the PC age is drawing to a close,” he says.

Connectivity trumps processing power in this new era. The developing world has a unique opportunity to leapfrog previous generations of technology, so why burden it with outdated technology?”

Dean says it is, therefore, not surprising “that the well-meaning efforts of the One Laptop Per Child programme have met with disappointing results. It's pushing the wrong product.”

Numbers

The numbers back him up. Internet World Stats estimate that only about 44.3 million of Africa's one billion people use the Internet. Although this number represents 882.7% growth since 2000, Africa's Internet penetration as a percentage of the population is still low (4.7%) versus the rest of the world (22%).

Meanwhile, GSM Africa, the African arm of the world GSM Association said in April that Africa's GSM mobile subscriber base was expected to jump to 316 million by year-end. The figure has rocketed in recent years, jumping from 63 million users in 2004 to 152 million in 2006 – and now doubling again.

The Globalist reported earlier this year that mobile phone penetration in the developing world, including Africa, had made “cellphones the first telecommunications technology in history to have more users there than in the developed world”.

In SA, seven out of every 100 South Africans had a cellphone 10 years ago. Today it is eight out of 10.

Cellphone versus PC

Dean concedes that the mobile phone cannot do everything a PC can. But he insists it is “a more reasonable first step into the digital age for developing countries”.

For one thing, he says, it is cheaper: “Even the least expensive laptop on the market cannot compete with a device that retails for $40 or less.

“Mobile phones are more portable, and their extended battery life is suited to regions where access to electricity is lacking or non-existent. And the infrastructure needed to connect wireless devices to the Internet is easier and less expensive to build.”

Dean adds it's important not to impose a Western bias when comparing the relative merits of mobile phones and PCs.

“For example, most African cultures rely on oral communication rather than the written word. And… mobile devices are much more than phones in emerging nations. Digital cash transactions, telemedicine, mobile banking and video are already de rigueur in many regions.”

Dean says mobile phones are evolving, too, increasingly offering many of the aspects of PCs. “We are already seeing emerging technologies coming to mobile phones, including tiny devices that can project images from the cellphone onto a wall, overcoming the small screen sizes, and even devices that enable full-size keyboards, bringing the QWERTY keyboard to the mobile phone.

“Over the past year, I've travelled extensively across sub-Saharan Africa and talked with students, business leaders and government officials as part of IBM's Global Innovation Outlook.

“They all say the path to prosperity is wireless. There is no learning curve, no literacy barrier and no technical-support challenge to overcome when it comes to the mobile phone. There are no costly and burdensome applications to load, maintain and update.

“Programs are called up as needed, and the potential for expansion of the services delivered over mobile devices is limitless,” says Dean.

“So before we exhaust ourselves arguing over which microprocessor the developing world needs to power its laptops, or unloading our outdated PCs on emerging markets, let's carefully consider the right technology for the ambitious effort of bridging the digital divide. The answer may already be in your pocket.”

Intel takes aim at Nvidia, AMD’s ATI

Intel is wading into the graphics chip market and its wake could roil Nvidia and AMD’s ATI.

On Monday, Intel is disclosing details (Techmeme) about Larrabee, a chip that will have stand alone graphics processing and aim for the gaming market. While Nvidia and AMD will poke holes in Larrabee the effort may miss the point. Intel can ruin pricing and squeeze its counterparts by just revealing its hand. Larrabee will land in 2009 or 2010.

Jon Peddie writes at Peddie Research:

Anyone not stuck in outer space or maximum security knows Intel is going to introduce a new chip code named Larrabee. At Siggraph they are going to reveal, after almost two years of teases and leaks, the architecture of the device.

It is not a GPU as many have mistakenly described it, but it can do most graphics functions, Intel says it can do all, we’ll have to wait for proof. Right now its slide-ware, but development systems are supposed to become available in November.

ATI and Nvidia will be very busy discrediting the device and pointing out its shortcomings. They should, given that Intel has all but ruined their share prices with disparaging comments about GPUs. Perhaps Intel needs to be reminded of some of its past triumphs; the Itanium and XScale come immediately to mind.

Peddie then examines whether there’s a market for a third graphic player and concludes yes.

Brooke Crothers also recaps Intel’s technology and new features such as software-based scheduling, execution threads, and ring networks.

Is Larrabee a guaranteed win? No, but Intel is likely to be very disruptive and squeeze both Nvidia and ATI.

ASUS Eee PC 900A: just like the 901

ASUS seem to be going a little over the top now, they are flooding the market with a range of different Eee PC’s but with not much difference. You only have to look at their latest offering, the ASUS Eee PC 900A. This laptop is much the same as the 901, with just a couple of small changes.

The 900A uses the same case as the 901, but has no Bluetooth and a rubbish .3 megapixel webcam.

All other specs are the same, down to the 1.6GHz Atom CPU, 8 or 16GB SSD and 1GB of RAM.

I do have to wonder why ASUS are trying to flood the market with a range of Eee PC’s, most of which are all the same inside, with just little changes.

The ASUS Eee PC 900A costs €299 ($465), not sure if it is worth it or not, only time will tell.

Asus Eee Box Sold Out in Taiwan

Just like the Asus Eee PC when it was first released, the first batch of the Eee Box in Taiwan has sold out since the July 30th launch date. That's pretty amazing - 1,000 units gone in approximately 5 days. This bodes well for Asus and their bottomline, but will the Eee Box have an impact as great on the home desktop market as with how the Eee PC kickstarted the whole netbook mania? We shall see. I must commend Asus for making affordable, entry level PCs even cheaper for the masses - surely developing countries with not much purchasing power will settle for the Asus brand instead of something more established and expensive.

Intel details future 'Larrabee' graphics chip

Intel has disclosed details on a chip that will compete directly with Nvidia and ATI and may take it into unchartered technological and market-segment waters.

Larrabee will be a stand-alone chip, meaning it will be very different than the low-end--but widely used--integrated graphics that Intel now offers as part of the silicon that accompanies its processors. And Larrabee will be based on the universal Intel x86 architecture.

The first Larrabee product will be "targeted at the personal computer market," according to Intel. This means the PC gaming market--putting Nvidia and AMD-ATI directly into Intel's sights. Nvidia and AMD-ATI currently dominate the market for "discrete" or stand-alone graphics processing units.

Larry Seiler (standing, middle), a senior Intel engineer, and Stephen Junkins (sitting, right), an Intel graphics software architect, speak at a briefing on Larrabee chip, due in 2009-2010.

As Intel sees it, Larrabee combines the best attributes of a central processing unit (CPU) with a graphics processor. "The thing we need is an architecture that combines the full programmability of the CPU with the kinds of parallelism and other special capabilities of graphics processors. And that architecture is Larrabee," Larry Seiler, a senior principal engineer in Intel's Visual Computing Group, said at a briefing on Larrabee in San Francisco last week.

"It is not a GPU as many have mistakenly described it, but it can do most graphics functions," Jon Peddie of Jon Peddie Research, said in an article he posted Friday about Larrabee.

"It looks like a GPU and acts like a GPU but actually what it's doing is introducing a large number of x86 cores into your PC," said Intel spokesperson Nick Knupffer, alluding to the myriad ways Larrabee could be used beyond just graphics processing. In addition to the PC, high-performance computing and workstations are two potential markets that Intel also mentioned.

Intel describes it in a statement as "the industry's first many-core x86 Intel architecture." Intel currently offers quad-core processors and will offer eight-core processors based on its Nehalem architecture, but Larrabee is expected to have dozens of cores and, later, possibly hundreds.

The number of cores in each Larrabee chip may vary, according to market segment. Intel showed a slide with core counts ranging from 8 to 48.

The individual cores in Larrabee are derived from the Intel Pentium processor and "then we added 64-bit instructions and multi-threading," Seiler said. Each core has 256 kilobytes of level-2 cache allowing the size of the cache to scale with the total number of cores, Seiler said.

Application programming interfaces (APIs) such as Microsoft's DirectX and Apple's Open CL can be tapped, Seiler said. "Larrabee does not require a special API. Larrabee will excel on standard graphics APIs," he said. "So existing games will be able to run on Larrabee products."

So, what is Larrabee's market potential? Today, the graphics chip market is approaching 400 million units a year and has consolidated into a handful of suppliers. "And of that population, two suppliers, ATI and Nvidia, own 98 percent of the discrete GPU business." according to Peddie.

"And the trend line indicates a flattening to decline in the business...However, Intel is no light-weight start up, and to enter the market today a company has to have a major infrastructure, deep IP (intellectual property), and marketing prowess--Intel has all that and more," Peddie said.

Though more details will be provided at Siggraph 2008, some key Larrabee features:

Larrabee programming model: supports a variety of highly parallel applications, including those that use irregular data structures. This enables development of graphics APIs, rapid innovation of new graphics algorithms, and true general purpose computation on the graphics processor with established PC software development tools.

Software-based scheduling: Larrabee features task scheduling which is performed entirely with software, rather than in fixed function logic. Therefore rendering pipelines and other complex software systems can adjust their resource scheduling based each workload's unique computing demand.

Execution threads: Larrabee architecture supports four execution threads per core with separate register sets per thread. This allows the use of a simple efficient in-order pipeline, but retains many of the latency-hiding benefits of more complex out-of-order pipelines when running highly parallel applications.

Ring network: Larrabee uses a 1024 bits-wide, bi-directional ring network (i.e., 512 bits in each direction) to allow agents to communicate with each other in low latency manner resulting in super fast communication between cores.

"A key characteristic of this vector processor is a property we call being vector complete...You can run 16 pixels in parallel, 16 vertices in parallel, or 16 more general program indications in parallel," Seiler said.
