U.S. Takes Back Supercomputing Crown
The U.S., once again, is home to the world’s most powerful supercomputer after being kicked off the list by China two years ago and then again by Japan last year.
The top computer, an IBM system at the Department of Energy’s Lawrence Livermore National Laboratory, is capable of 16.32 sustained petaflops, according to the Top 500 list, a global, twice a year ranking, released Monday.
This system, named Sequoia, has more than 1.57 million compute cores and relies on architecture and parallelism, and not Moore’s Law, to achieve its speeds.
“We’re at the point where the processors themselves aren’t really getting any faster,” said Michael Papka, Argonne National Laboratory deputy associate director for computing, environment and life sciences.
The Argonne lab installed a similar IBM system, which ranks third on the new Top 500 list. “Moore’s Law is generally slowing down and we’re doing it (getting faster speeds) by parallelism,” Papka said.
U.S. high performance computing technology dominates the world market. IBM systems claimed five of the top ten spots in the list, and 213 systems out the 500.
Hewlett-Packard is number two, with 141 systems on the list. Nearly 75% of the systems on this list run Intel processors, and 13% use AMD chips.
Intel Buys Patents
Intel on Monday spent US$375 million to purchase nearly 1,700 wireless networking patents from subsidiaries of digital communications company Interdigital.
Intel will get patents that cover a range of 3G, LTE and Wi-Fi technologies from Interdigital. The patents should boost Intel’s product mobile product portfolio as the company establishes a presence in the smartphone and tablet markets, which is currently ruled by ARM.
Intel has said it will integrate 3G and 4G LTE capabilities along with its Atom microprocessor in devices like smartphones and tablets. Intel made its first entry into the smartphone market earlier this year with its Atom chip code-named Medfield, which is being used in handsets from Lenovo, Orange and Lava International.
Intel later this year will release a dual-core Atom Z2580 processor with 3G, 4G and LTE capabilities. Intel’s upcoming Atom chip for tablets, code-named Clover Trail, will also come with mobile broadband options.
Intel started building its wireless business following the acquisition of Infineon Wireless for $1.4 billion, which was completed last year.
Wireless is a fast-changing market, and the company is making this investment to support the business, according to Chuck Mulloy, an Intel spokesman.
“This was an opportunity to add some value to our patent portfolio. That’s over and above what we have,” Mulloy said.
Intel Increasing Supplier Audits
Intel has audited almost five times as many of its suppliers in 2011 than it did the previous year.
Chipzilla set itself a target of visiting 50 on-site, third-party audits of its suppliers during the last year. It had that target last year as well, but missed it by only carrying out 49 audits, while one had to be rescheduled.
In comparison Intel only carried out eight visits in 2010. The company also conducted 249 in-depth assessments and 289 self-assessments by suppliers.
But the findings were not that great. Intel found 426 priority and major findings, the highest class of non-compliance as defined by the company.
Most of the non-compliance related to management systems such as a lack of documentation and systems for CSR, inadequate communication with workers or suppliers and a lack of audits. But there were also 112 instances of labour abuse, which included working hours of more than 60 hours per week, and workers not being given at least one day off a week. There were also 28 issues relating to ethics, such as not having an anonymous reporting line for employees to raise issues or concerns through.
The report was interesting because it must have covered Foxconn, which has been the subject of criticism over its treatment of workers. During 2011, Intel carried out audits at three Foxconn facilities and found them about as bad as others in the region. Most of the breaches of rules were in the areas of labour conditions, safety systems, and management systems.
AMD, ARM And Others Form HSA Chip Foundation
Comments Off on AMD, ARM And Others Form HSA Chip Foundation
AMD, ARM, Imagination Technologies, Mediatek and Texas Instruments have signed up to create the Heterogeneous System Architecture Foundation (HSAF).
AMD has been pushing its vision for heterogeneous computing, where CPUs and GPUs can share system resources such as memory allowing developers to treat any processing core as a black box. Now the firm has managed to rope in ARM, Imagination Technologies, Mediatek and Texas Instruments to create the non-profit HSAF.
According to AMD, HSAF will try to define a hardware specification for developers to standardise upon, which should make development quicker and easier.
Phil Rogers, HSAF president and AMD corporate fellow said, “HSA [heterogeneous system architecture] moves the industry beyond the constraints of the legacy system architecture of the past 25-plus years that is now stifling software innovations. By aiming HSA squarely at the needs of the software developer, we have designed a common hardware platform for high performance, energy efficient solutions. HSA is unlocking a new realm of possibilities across PCs, smartphones, tablets and ultrathin notebooks, as well as the innovative supercomputers and cloud services that define the modern computing experience.”
AMD has scored something of a coup by getting big names such as ARM, Imagination and Texas Instruments to back its vision of a heterogeneous system architecture. Although the company has been struggling in outright performance terms against Intel, the idea of a combining CPU and GPU resources and making them appear as one to the application is something that will help it leverage its GPU compute capability against Intel.
Qualcomm Chip Issues Should End By December
Comments Off on Qualcomm Chip Issues Should End By December
Qualcomm said it believes TSMC’s 28nm supply issues will continue until year end.
Qualcomm, which relies solely on TSMC for its 28nm chips, said it believes the supply of chips will improve, but the firm expects its 28nm supply not to be back to normal until the end of 2012.
Previously Qualcomm had poured scorn on TSMC by telling investors it is looking at rival wafer fabs to avoid supply issues in the future. Qualcomm’s CEO Paul Jacobs told Reuters once again that the firm is looking to other foundries for extra capacity, adding, “The goal is to get enough supply for everyone.”
TSMC’s 28nm process node has been tapped by a number of big name customers including AMD, Nvidia and Qualcomm, with the chip fab unable to meet demand. Since Qualcomm made the rare public admission that it wasn’t happy with the state of TSMC’s 28nm chip supply, the smart money has been on Globalfoundries picking up the slack, however nothing specific has been announced by either firm.
Qualcomm Updates The S4 Series
Qualcomm’s Snapdragon S4 chips are proving to be quite a coup for the company. They are faster than anything the competition has to offer, more power efficient and some versions include integrated LTE. The only problem is that Qualcomm is having trouble meeting demand.
Qualcomm announced four new S4 chip series aimed at wildly different market segments, all based on the very successful Krait architecture.
Snapdragon S4 Prime chips will target smart TVs and similar applications. The first Prime part is the MPQ8054, a 1.5GHz quad-core with Adreno 320 graphics. Qualcomm promises “leading” audio/video capabilities and low power consumption, although we are not sure efficiency very important in TVs.
Meanwhile Snapdragon S4 Pro parts sound like all-rounders. They also feature Adreno 320 graphics and the S4 Pro tier includes the APQ8064 quad-core and MSM8960T, the Pro version of MSM8960. Pro parts are likely to end up in tablets, hybrids and other “ultra-thin and sleek” devices.
S4 Plus parts are geared towards the traditional mobile market, smartphones and tablets, ranging from the low-end to the high-end. Processors in the S4 Plus tier include MSM8960, APQ8060A, MSM8660A, MSM8260A, APQ8030, MSM8930, MSM8630, MSM8230, MSM8627 and MSM8227.
AMD Gives Opteron A Boost
AMD has shown there is a little life left in its Bulldozer Opterons by bumping up the clock speed of five Opteron models.
AMD launched its Bulldozer Opteron processors last November amid widespread anticipation that its brand new Bulldozer architecture would once again make it competitive with Intel. Its new architecture failed to impress, but the company has managed to eek out another 100MHz from five Opteron processors in what is likely to be a last hurrah before Piledriver Opterons make their appearance.
AMD bumped up the clocks by 100MHz on the 16-core Opteron 6284 SE and Opteron 6278 to 2.7GHz and 2.4GHz, respectively, while keeping TDPs the same as before, at 140W and 115W, respectively. The firm gave four Opteron 4200 series chips the same 100MHz bump, including the eight-core Opteron 4276HE to 2.6GHz, the six-core Opteron 4240 to 3.4GHz and the Opteron 4230 to 2.9GHz.
AMD was keen to point out that its speed bumped Opteron chips have been picked by Dell and by HP for 11 of its servers. Although the firm has not been able to compete with Intel’s Xeon chips on perfermance, its chips are considerably cheaper, a fact that AMD is using to win customers.
Although AMD’s 100MHz speed bump isn’t going to set the world on fire, every little bit of performance will help the firm as Intel ploughs on with its hugely impressive Sandy Bridge E and Ivy Bridge Xeon chips. AMD’s answer to Intel’s latest Xeon chips is expected to be the Piledriver Opterons.
Adata Outs 40MB/s UHS microSD Card
Adata has launched a 32GB UHS-1 microSD card offering 40MB/s write bandwidth.
Adata, which recently has been making a big push in the solid-state disk (SSD) drive market, has announced its first microSD cards that support the UHS-1 specification. The firm’s Premier Pro cards come in 8GB, 16GB and 32GB capacities with the firm citing read bandwidth of 45MB/s and all important write bandwidth of 40MB/s.
The SD Card Association defined the UHS-I specification as part of its SD Version 3.01 standard, and while Adata’s new cards boast impressive speeds there is a lot of headroom left, with UHS-1 supporting bandwidths up to 104MB/s. Adata’s cards, roughly translated to the ‘X’ speed rating used on a number of memory cards, come out at 266X.
Ray Chu, product manager at Adata said, “These cards have the best read and write performance among all comparable products offered by the industry’s key players. When that is combined with the aggressive pricing options in store for this line, the result is going to be a bonanza for our customers worldwide.”
Will Window 8 Tablets Launch In November?
Comments Off on Will Window 8 Tablets Launch In November?
The first Windows 8 tablets should hit retail sometime in November and we could see a bunch of devices in different form factors.
According to CNET’s Brooke Crothers, the first wave of Windows tablets will include more than a dozen devices, but more than half of them will be hybrid designs. So, it seems Microsoft and vendors are betting on traditional keyboards to set Windows tablets apart from the competition.
The new tablets will be based on Intel’s dual-core Clover Trail Atoms, but bear in mind that Microsoft will also release Windows for ARM chips and AMD could also enter the fray with some low-voltage APUs.
Is Moore’s Law Dead?

Comments Off on Is Moore’s Law Dead?
Physicist Michio Kaku says that Moore’s law will be dead within about 10 years.
Kaku, professor of theoretical physics at City University of New York told BigThink.com that we are already seeing a slowing down of Moore’s Law. He said that computing power simply cannot maintain this rapid, exponential rise using standard silicon technology.
Kaku said that the latest CPUs from Intel, which use a unique three-dimensional design, do continue roughly doubling processors. But he points out that the new design is nonetheless proof that the Law is winding down.
The two basic problems are heat and leakage and that is why the age of silicon will eventually come to a close.
By continuing to shrink the parts that go into processors, heat becomes concentrated. At a point in the near future, the heat generated will be so intense that the chip will melt. You can literally fry an egg on top of the chip, and the chip itself begins to disintegrate, he said.
