Supercomputer powers Japan back to top spot

June 21st, 2011

Japanese computer geeks are celebrating a comeback after a Fujitsu-built supercomputer set a world speed record – beating the reigning Chinese machine and giving Japan the most powerful computer for the first time in seven years.

The Fujitsu “K” – a play on the Japanese word for 10,000,000bn, the number of operations per second it is designed to perform – topped the semi-annual ranking announced on Monday at the International Supercomputing Conference in Hamburg.

This is proof that our nation’s technology sector is still healthy,” said Ryoji Noyori, project director at Riken, a government-funded research institute that collaborated with Fujitsu. “We have to aim for top spot.”

Japan first took the fastest-computer title in 1990, startling the long-dominant US. Machines from Fujitsu, NEC and Hitachi traded places at the top of the rankings for the next 50 years and an NEC supercomputer, Earth Simulator, held the crown from 2002 to 2004.

But with Japanese industry struggling for 20 years and China moving ahead in economic output, many questioned whether Japan was still up to the task. The K’s government funding was nearly revoked last year, with the minister in charge asking: “What’s wrong with being number two?”

Fujitsu refuses to say how much it has spent, but about 1,000 engineers have worked on various aspects of the K’s hardware and software, all of which was developed in-house.

The earthquake and tsunami in March also created delays. The warehouse-sized K is located in Japan’s western city of Kobe, away from the disaster zone, but at least two subcontractors in the devastated north-east suffered damage, including one that makes housings for the computer’s 68,544 interlinked central processors.

The K will not be completed until next year. But its current certified speed of 8.16 petaflops (8.16 quadrillion operations a second) is still three times faster than the next-quickest machine, the Tianhe-1A, built by China’s National University of Defence Technology with processors from Nvidia, the California-based graphics chip design company.

Fujitsu and Riken officials said the K would be used for complex computer modelling in pharmaceuticals, material science and climatology.

One of its tasks is likely to be generating simulations of earthquakes and tsunamis. “We want to use this as a catalyst to rebuild Japan,” said Kimihiko Hirao, deputy project director at Riken.

The K is unlikely to keep its title for long, however. US researchers are also working on supercomputers capable of 10 petaflops or more, and one project scheduled for completion next year, from IBM and the Lawrence Livermore National Laboratory, is aiming for 20 petaflops.

Solving Mysterious PC Slowdowns

June 21st, 2011

If you’re having issues with the speed of your Windows PC, you might be tempted to think that a defrag and perhaps purchasing some extra memory might suffice.

However, there are other reasons for slowdowns beyond a hard disk drive dropping data wherever it likes and a realization that modern apps require a bit more RAM. While there can be plenty of software reasons for slowness (and these can be quickly resolved with a few minutes of attention using tools provided in Windows 7) the hardware reasons are worth investigating first.

For instance, PCs can get too hot, which results in the CPU running slower. The BIOS might lose settings and run RAM at the wrong speed, or the amount of RAM on your system might appear to shrink.

Finally, a hard disk drive issue could be the cause of your slow Windows 7 computer. Let’s take a look at each of these factors and how they can be resolved.

Vanishing System Memory

Older systems or those that are regularly modified can occasionally see the BIOS reset itself. This can happen if the BIOS battery runs out, and when this happens, the settings in the BIOS revert to the defaults.

One of the things that this can affect is the speed of your RAM. While modern motherboards usually auto-detect RAM speeds based on the modules, this isn’t the case on all devices, so you should check that your system memory is set to the correct speed in the BIOS.

It is also possible that your RAM might appear to shrink. The Intel P55 and X58 chipset motherboards feature a quirk that results in RAM not being correctly detected. This occurs when a heatsink is mounted too tightly, causing a kink in the motherboard and preventing the RAM module from being detected.
Overheating Components

If your PC gets too hot, it will shut down as a safety precaution in order to protect the hardware. Finding out why your PC is getting too hot is another matter, however. If your PC is lagging for some reason, checking any desktop temperature monitoring that you have installed is a good idea. This will usually be supplied with your motherboard as it depends on the sensors provided on the device, but can be a very useful tool to have.

Not all motherboards have this feature, so the next thing to check is the amount of dust in your computer. Modern cases often have dust filters across the air intakes on the PSU, so removing and cleaning this is a good step to take, as is keeping the area around your PC clean and tidy and regularly vacuumed.
Hard Drive Failure Imminent?

If you suspect that your hard disk drive is about to give up – something that you should be able to detect from seeming constant use (a regular rattling sound) – then you will need to take steps to remove data from it to another device.

This is best done by copying data to a secondary, faster internal hard disk drive, but if this isn’t possible then you should use an external device to copy all of your vital files and folders to, and then replace the failing disk drive.

You will find that this requires you to reinstall Windows; if you have a copy of the operating system that will install, then use this, otherwise you will need to take the computer back to the supplier for them to deal with installation.

Dell’s lessons in Indian manufacturing push

June 20th, 2011

Computers leaving the assembly line go to millions of newly affluent Indians feeding an explosion in consumer demand. But the boxes of component parts on the floor say “Made in China”.

That fact alone says a lot about how far the country’s manufacturing sector has to go to match its world famous information technology and services prowess and sustain searing economic growth. India needs to crank up its industrial base to wean itself from service sector-led growth and tame a trade deficit which could more than double in three years, mainly because of billions of dollars worth of Chinese imports.

Shabby infrastructure, cumbersome bureaucracy, a meandering tax regime and a nascent local supplier base are holding back industrial growth and more foreign investment. “We are really taking baby steps in the IT manufacturing space,” Dell Executive Director M R Sundaresan said. “We have a huge opportunity to be able to build on this.”

“Electronics are still largely imported into the country,” he added. “We don’t have a component or parts manufacturing supply chain available in the country.”

While Dell is bullish about India’s prospects as a global growth driver, it is held back by issues ranging from a pesky permit system and the country’s fragmented taxation methods. One of the biggest challenges is an underdeveloped supplier base to make components, such as microprocessors, locally. The result is a “chicken and egg” dilemma for the country. Dell needs component makers to set up shop in India, but big players will only come when there are enough Dells to drive demand. This matters, because India can no longer rely on a mix of its IT and service sector clout, remittances from its citizens working overseas and capital flows to finance a huge import bill of one of the world’s fastest growing economies.

Dell’s challenges are by no means unique, but reflect what firms grapple with as they seek to expand in one of the world’s hottest economies, from stifling labour laws to sudden government changes that catch companies off guard.

Dell prides itself on making desktops and laptops to order, delivering from the factory straight to a customer. But sending a finished item to certain Indian states requires the customer to obtain a permit from a local tax officer, which the delivery truck driver then has to produce at state checkpoints.

“It’s an impediment to the ease of doing business,” Sundaresan said. “The transport industry is highly immature, fragmented,” he said, adding, “The guy who comes and delivers it to your home, is not a company. He’s still a person who owns one truck.”

Dell’s annual revenue in India is closing on $2 billion. Its factory in Tamil Nadu, one of India’s most business friendly, caters to 90 per cent of local demand. But most of the components needed to assemble computers are sourced overseas.

The rise of Texas-based Dell Inc, the world’s second largest maker of personal computers, as a manufacturing heavyweight in India is a snapshot of how the country is striving to follow in China’s footsteps as an industrial giant. Dell started in India as a services provider, setting up shop in 1996 and opening up a series of call centres for customer support to anywhere from the US to Africa and riding a crest of a software and services boom that has tagged India as the back office to the world.

The tipping point for demand came in 2007. Strong double digit growth in computer sales in India had made the time ripe for Dell to set up a manufacturing hub to lower costs and slash delivery times to customers, helping it to expand in a bulging white collar market with economies of scale. It now employees nearly 25,000 people in the country, second only to the US.

Dell also prides itself on having been the country’s first major personal computer exporter out of its Indian factory, Dell’s third in the Asia-Pacific region, selling mainly to markets nearby in the Middle East. In time, greater expansion could follow. “If I get more and more of my ecosystem locally, there is no reason why I shouldn’t be able to ship to western Europe as well as to the US,” Sundaresan said.

Asia’s third-largest economy is starting to shed its status as a manufacturing laggard with an influx of global big-hitters, to a sector once infamous for its red tape, countless licence requirements and pitiful output before liberalisation.

The town, Sriperumbudur, is about an hour’s drive from Chennai. It is known for two things: it is where the technology-loving Prime Minister Rajiv Gandhi was assassinated by Tamil Tiger rebels in 1991, the same year India unleashed economic reforms which sowed the seeds of today’s 8.5 percent boom. It has also since become a magnet for foreign giants such as Dell, Nokia and South Korea-based Hyundai Motor Co, as part of Tamil Nadu’s industrial belt also known as “India’s Detroit”.

The government is pinning its hopes on the growth of the likes of Sriperumbudur to lift manufacturing to 25 per cent of GDP from about 16 per cent by 2025 to create jobs for tens of millions expected to join the workforce during that time.

The Tamil Nadu government won praise for attracting investors with tax incentives, easy access to land and an educated workforce. Proximity to sea ports and an airport are also key factors. Dell has reciprocated by hiring hundreds of factory workers from the state’s rural hinterland, giving them the chance to become more fluent in English, take correspondence courses with colleges and send money back home to their families. “I want to build my future here,” 21-year-old Manikandan, who takes apart dud computers at the factory, said.

However, no matter what incentives companies such as Dell get from states, national problems persist. Chennai’s sea port is the export-import point for many multinational firms who set up nearby. But the road to the port is strewn with trash, has shabby shops and slums with thatched roofs. Trucks have to wait in a queue which can be more than a mile long to unload their cargo. Reuters spoke to one truck driver near the end of this queue at quarter past five in the afternoon. He said he had been waiting there since ten in the morning.

Chennai port is not alone in this. Many of India’s roads and ports are clogged and underdeveloped. The average cost to move a container around within India is $945, more than double the $460 it costs in China. And it’s not just infrastructure. Foreign investors and local firms alike have long pushed for Prime Minister Manmohan Singh’s coalition to implement a Goods and Services Tax to simplify the country’s tax regime. “It’s not about giving freebies or anything,” Dell India President Ganesh Lakshminarayanan said. “It’s about having a stable tax regime which can signal to the component manufacturers, signal to companies like Dell, that the business environment is going to be stable.”

The government is trying to foster industrial growth, setting up manufacturing zones like China’s with the help of tax breaks, flexible labour laws and world class infrastructure to attract foreign players and foster export growth. But such initiatives have been a mixed bag. Getting land is tough, while ministries have clashed over how to implement such zones and how much the companies should be taxed, if at all. While Dell flourished to become India’s top computer hardware seller, others may have a tougher time. Tamil Nadu’s industrial rise, for example, may be becoming a double-edged sword with its infrastructure starting to rip at the seams. As well as clogged up ports, businesses complain of long blackouts.

“Manufacturing has suffered quite a lot in the past ten years,” said Shanker Gopalkrishnan, president of the Madras Consultancy Group, of Tamil Nadu industry. “If you don’t service these industries well, there is a danger of losing business to another country.” Whatever its problems, companies such as Dell remain bullish about India’s prospects, even if it may not eclipse China. “India is the most exciting thing we get to talk about,” Lakshminarayanan said. “The whole point is acknowledging China’s growth in the manufacturing sector and positioning India as the next best destination,” he added.

Techsol’s Touch Screen Computer Module (TSCM) Simplifies Creation of Touch Screen Computers

June 20th, 2011

Technical Solutions Inc. (Techsol) releases a new, modular touch-screen computer product line. In 3 simple steps, choose your LCD screen (with matching adapter board), computer module, and I/O module and you have the guts of a touch-screen terminal customized exactly to your needs!

Why just 2? Why not all 3?

When you tell your engineers that you’re finally pulling the trigger on that long overdue update to your product line, replacing character displays with color touch-screens, or modems with Ethernet and Cloud-computing they give you the same old story:

“Your options are:

* High-performance
* High-quality
* Low-cost

Pick any 2!
Because everyone knows you can only have 2.”

What if you demand all 3? Why not? You didn’t get where you are by following the crowd. What if “common wisdom” is really “urban myth”? Tell them you want all 3 or they’re all fired! Then, after they catch their breath, give them this link: medallionsystem.com/cpu-modules/tscm/

“What’s there?” they say. How about the world’s first low-cost, high-performance, modular touch-screen computer system based on the highest quality components and built in North America! You get all 3 in 3 simple steps:

* pick your display (it comes with a matching display interface board supporting LCD, touch, back-light, plus some optional extras)
* pick your computer power, from 500 to 1000 MIPS, with or without on-board Ethernet
* pick your mix of I/O and power-supply. From POE to a super-low-cost 2-board option powered by USB, there’s a range of boards coming.

And then when you get them, just stack them together and turn on the power!

That’s it.

Using the latest i.MX processors from FreeScale Semi-conductor of Austin Texas, Techsol’s engineers have applied 1/4 century of experience designing low-power CMOS computer systems for commercial, industrial, medical, automotive, and defense applications to the long-standing challenge of “why not all 3″. Plus, all TSCM products run Techsol’s Medallion Linux, one of the oldest and most stable Linux distributions exclusively targeting ARM processors (for over 10 years).

Display options currently supported include 3.5″, 4.3″, 5″ WVGA, 7″ WVGA, 7″ Hi-Brite, and 10.4″ SVGA LVDS with more coming.

Conceived in 2007, designed starting in 2009 (there was a recession providing time :) , optimized in 2010, and now rolling out in 2011, the Touch Screen Computer Module (TSCM) simplifies the creation of your next product at low-cost, with low-risk, and with fast time-to-market. Plus, Techsol still offers custom design services should you require a unique mix of interfaces or power-supplies on your I/O board or support for a new display.

Techsol has done the work. And you reap the rewards! Call us now to get started on that new design.

Embedded Engineering is the same all over the world. Engineers face the same challenges of having too much to do, and not enough time or money to do it with. Techsol’s Medallion Classic and TSC modules address this issue and provide a solution that extends into the production stages of a product, not just the proof-of-concept stage like most SBCs.

Techsol’s Medallion system is unique in the embedded computer world.
The Medallion Single-board computer product line encompasses multiple CPUs, and different configurations with the same CPU. However, the pin-out and form-factor remain the same, even after 10 years.
And the TSCM will also have a long availability for “planned NON-obsolesence”.
There is one Medallion module that is best matched to your application.

By designing with the Medallion system, you are effectively out-sourcing your CPU design and Linux porting with no up-front NRE fees! That lets your team concentrate on the hardware and software portions of your product that your customers see. The result is that you can create a higher-quality product in a fraction of the time (and cost) of designing everything yourself from scratch! Plus, the interchangeable modules extend product life-cycle times.

The iCloud FAQ: top five Q&As to clear the air

June 20th, 2011

At Apple’s Worldwide Developers Conference 2011 in San Francisco this June, the company announced a trio of new software offerings — Mac OS X 10.7 Lion, iOS 5 and iCloud — with Apple CEO Steve Jobs introducing the products like so: “If the hardware is the brain and the sinew of our products, the software in them is their soul.”

It’s a fairly apt analogy, for while the company makes most of its money on hardware sales, it’s Apple’s various software UIs and features (and their often seamless behind-the-scenes integration) that makes the overall hardware deal so compelling for Mac and iOS users (oh, that and those designer chassis).

And speaking of users, that’s a numbers game that Apple is pretty much owning at the moment: in the past year the company has overtaken its traditional rival Microsoft in market capitalisation, revenue and profit; Mac sales grew by 28 per cent in the last twelve months, even as the overall PC market fell by one per cent, culminating in the fifth straight year in which Mac sales have outgrown overall PC industry sales; and to top it all off, Apple has sold more than 200 million iOS devices (iPhone, iPad and iPod touch) to date, which gives the company a 44 per cent share of what it calls the “mobile market”. Apple has long presented itself as the challenger brand, but make no mistake: it’s now the establishment.

But while the Mac OS X 10.7 Lion and iOS 5 announcements at WWDC this year concerned fundamentally important software platforms for Apple, if there was ever any doubt over which of this year’s keynote topics took precedence, you only had to look at who was making the presentation: after Phil Schiller (SVP WW Product Marketing) and Scott Forstall (SVP iOS Software) showed off Lion and iOS 5 respectively, Steve Jobs — officially on indefinite medical leave — took the stage to unveil iCloud: Apple’s new cloud initiative to integrate and sync all aspects of your digital life in 2011 (and beyond) and arguably the company’s biggest platform play since ushering in the “Post PC” appliance era with the first iPod in 2001.

As Jobs got started, this is what he had to say about our evolving tech usage patterns over the past decade: “About 10 years ago we had one of our most important insights, and that was: that the PC was going to become the digital hub for your digital life. What did that mean? Well, it meant that that’s where you were going to put your digital photos… your digital video… and of course your music…. You were going to basically sync [all your digital content] to the Mac, and everything was going to work fine. And it did, for the better part of ten years, but it’s broken down in the last few years.”

“Why? Well, because devices have changed. They now all have music. They now all have photos. They now all have video… And keeping these devices in sync is driving us crazy. So we’ve got a great solution for this problem. And we think this solution is our next big insight, which is: we’re going to demote the PC and the Mac to just be a device. Just like an iPhone, an iPad or an iPod Touch. And we’re going to move the digital hub, the centre of your digital life, into the cloud. Because all these new devices have communications built into them: they can all talk to the cloud whenever they want.”

Supercomputer “K computer” Takes First Place In World

June 20th, 2011

This ranking is based on a performance measurement of the “K computer(1),” currently under their joint development.

The TOP500-ranked K computer system, currently in the configuration stage, has 672 computer racks equipped with a current total of 68,544 CPUs. This half-build system achieved the world’s best LINPACK(2) benchmark performance of 8.162 petaflops (quadrillion floating-point operations per second), to place it at the head of the TOP500 list. In addition, the system has recorded high standards with a computing efficiency ratio of 93.0%. This is the first time since June 2004 that the Japanese supercomputer “Earth Simulator” has been ranked first on the TOP500 list.

RIKEN and Fujitsu have been working together to develop the K computer, with the aim of beginning shared use by November 2012, as a part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT). The K computer will be comprised of over 800 computer racks – each equipped with ultrafast and energy-efficient CPUs – that access into a network capable of an immense amount of interconnectivity. The supercomputer system brings together leading-edge technologies for high performance and high reliability.

To test the system’s performance at the configuration stage, the K computer’s processing speed was measured by the LINPACK benchmark program, placing it on the 37th TOP500 ranking of the world’s fastest supercomputers. The TOP500 ranking list began in 1993 and is updated twice a year in June and November.

Performance and Future Status of the K computer

The LINPACK benchmark program, running on the part of the system that employs 68,544 CPUs installed on the K computer being configured, recorded the world’s top performance of 8.162 petaflops. This gave it the number-one position on the TOP500 list. Moreover, for one of the world’s largest supercomputers, it achieved an extraordinarily high computing efficiency ratio of 93.0%. This achievement is made possible by the K computer’s integration of technologies, including its massive number of CPUs, the interconnectivity that links them together, and the software that is able to bring out the highest performance from the hardware.

When configuration of the K computer is complete in 2012, it is designed to achieve LINPACK performance of 10 petaflops. It will be widely used in a variety of computational science fields where it is expected to contribute to the generation of world-class research results. The K computer is a wholly made-in-Japan supercomputer, from the research and development of the processors, to system design and manufacturing. Use of the K computer is expected to have a groundbreaking impact in fields ranging from global climate research, meteorology, disaster prevention, and medicine, thereby contributing to the creation of a prosperous and secure society. RIKEN and Fujitsu will continue to work tirelessly toward completing the system’s deployment in 2012.

Ryoji Noyori, President, RIKEN:
“I would like to express my deep gratitude to everyone, beginning with our colleagues at our development partner Fujitsu Limited, who worked so valiantly on the construction of the K computer even under the severe conditions following the Great East Japan Earthquake. It is wonderful to be able to share the joy of this moment with them. I very much believe that the strength and perseverance that was demonstrated during this project will also make possible the recovery of the devastated Tohoku region. As we move forward to complete this project by next June, we will maintain our firm commitment to the maintenance and operation of the system, and I hope to see wonderful results when we begin to make the world’s top performing supercomputer available to users around the world.”

Michiyoshi Mazuka, Chairman and Representative Director, Fujitsu Limited:
“I am delighted that we were able to achieve this result, made possible through the tremendous efforts of all involved, despite the impact of the Great East Japan Earthquake. In particular, I am sincerely grateful to our partners in the Tohoku region for their commitment to delivering a steady supply of components, even though they themselves were affected by the disaster. Bringing together hundreds of thousands of components to quickly launch such a massive-scale computing system – which would have been nearly impossible using conventional technologies – requires an incredible level of reliability. I believe that this reliability is truly the pinnacle of Japanese manufacturing. Without being too pleased with ourselves and losing sight of our goal, going forward we will proceed with the system’s deployment and, once complete, we look forward to contributing to the achievements that the K computer will make possible.”

(1) K computer: The K computer, which is being jointly developed by RIKEN and Fujitsu, is part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT). Configuration of the K computer began in the end of September 2010, with availability for shared use scheduled for 2012. The “K computer” is the nickname RIKEN has been using for the supercomputer of this project since July 2010. “K” comes from the Japanese Kanji letter “Kei” which means ten peta or 10 to the 16th power. The logo for the K computer based on the Japanese letter for Kei, was selected in October 2010. In its original sense, “Kei” expresses a large gateway, and it is hoped that the system will be a new gateway to computational science.

(2) LINPACK: A program developed by J. Dongarra, Ph.D., of the University of Tennessee, for solving a system of linear equations using matrix computation. It is the benchmark program used to create the TOP500 list, which ranks the performance of the world’s supercomputers (announced in June and November of every year).
