AMD Goes 16 Core Snowy Owl
Naples is a 32 Zen core Opteron with 64 threads. The 16 core Zen version with a BGA socket is codenamed Snowy Owl. AMD thinks that Snowy Owl will be a great match for the communication and network markets that needs a high performance 64-bit X86 CPU.
Snowy Owl has 16 cores and 32 threads, all based on 14nm FinFET Zen transistors. The processor supports up to 32MB of shared L3 cache. We also mentioned a processor cluster codenamed Zeppelin. This seems to be the key to the Zen architecture as more Zeppelin clusters are creating more core Opterons.
Each Zeppelin has eight Zen cores and each Zen core has 512KB dedicated L2 cache memory. Four Zen cores share 8MB of L3 memory making the total L3 cache size 16MB. Zeppelin (ZP) comes with PCIe Gen 3, SATA 3, 10GbE, sever controller Hub, AMD secure processor as well as the DDR4 Memory controller. AMD is using a super-fast coherent interconnect to create more than one Zeppelin core.
One Zeppelin cluster would make an 8 core, 16 thread CPU with 4MB L2 and 16MB L3 cache and in our case product codenamed Snowy owl has 16 cores, 32 threads 8MB of L2 (512KB x 16) and 32MB L3 (4x8MB).
The Snowy Owl with 16 cores uses a SP4 Multi Chip Module (MCM) BGA socket, while the Naples uses MCM based SP3. These two are not pin compatible but 16 and 8 core Zen based Opterons will fit in the same socket.
Snowy Owl has four independent memory channels and up to 64 lanes of PCIe Gen3. When it comes to storage, it supports up to 16 SATA or NVME storage channels and 8x10GbE for some super-fast networking solutions.
As you see, there will be plenty of Zen based Opteron possibilities and most of them will start showing up by mid-2017. The TDP Range for Snowy Owl is sub 100W and capable of sinking the TDP down to 35W. Yes, we do mean that there may well be a quad core Zen Opteron too.

AMD Goes After Intel’s Skylake With Bristol Ridge
Comments Off on AMD Goes After Intel’s Skylake With Bristol Ridge
AMD has revealed the firm’s seventh-generation system-on-a-chip accelerated processing units (APUs).
Bristol Ridge and Stoney Ridge sound a little like locations in a Somerset version of Game of Thrones, but they both feature AMD’s Excavator x86 processor cores and Radeon R7 graphics, which AMD sees powering e-sports gaming on laptops.
Bristol Ridge is the more powerful of the two coming in 35W and 15W versions of AMD FX, A12 and A10 processors, offering up to 3.7GHz of processing power. The former two processors are paired with up to eight Graphics Core Next (GCN) cores in the R7 to provide a decent pool of graphics processing power.
Stoney Bridge offers less in the way of processor power, topping out at 3.5GHz, and versions include 15W A9, A6 and E2 processor configurations coupled with lower powered graphics accelerators.
AMD claimed that the new APUs offer a 50 per cent hike in performance over the previous generation Carrizo APUs. However, this rise is over APUs from the early part of Carrizo’s lifecycle, so performance gains over the most recent Carrizo APUs are likely to be 10 to 20 per cent.
AMD also said that its silicon is faster than rival chips from Intel, including the i3-6100U found in several ultraportable laptops.
Many of these tests are subjective and depend on how a hardware manufacture configures and sets up the APUs in a laptop or tablet, but AMD does have its graphics tech to draw on, such as the GCN architecture, which could give it the edge over Intel’s chips when it comes to pushing pixels.
The APUs will be aimed primarily at slim laptops that need low-power consumption chips, much like Intel’s Skylake line.
Bristol Ridge is currently available to end users only in the form of HP’s latest Envy laptop. But now that AMD has debuted the full range of the seventh-generation APUs we can expect to see them in other ultraportable machines before too long.

Is nVidia Taking Qualcomm To Court?
Nvidia has dragged Qualcomm into court for allegedly crushing a $352 million chipset deal.
Nvidia claims it was forced to wind down its cellular mobile broadband chipset business, including its Icera unit just four years after buying it, because of Qualcomm’s anti-trust antics.
Qualcomm’s alleged tactics led to “unexplained delays in customer orders, reductions in demand volumes and contracts never being entered into, even after a customer or mobile network cooperating with a prospective customer has agreed or expressed a strong intention to purchase” Nvidia’s chipsets, the company moaned.
The claim for cash comes as European Union regulators step up antitrust investigations into Qualcomm sales tactics that officials said thwarted other designers of mobile-phone chip technology. This could result in fines or an EU order forcing a company to change its behaviour.
The EU thinks Qualcomm may have charged below-cost fees for chips used in mobile Internet modems known as dongles from 2009 to 2011 to thwart smaller competitor Icera. Regulators are separately probing what they say are exclusivity payments Qualcomm paid to a phone and tablet manufacturer for using its designs.
Qualcomm is “confident” it would prevail in both the EU investigation and the lawsuit.
Nvidia is seeking a declaration from the judge that Qualcomm’s conduct was an abuse of a dominant position, compensation, and an account of the profits it says Qualcomm gained from unlawful conduct, according to the court filings.

AMD’s Vegas GPU Details Spotted
Details of AMD’s Vega GPU were leaked and then taken down from AMD R&D Manager’s LinkedIn profile page over Easter.
Hexus spotted Yu Zheng, an R&D Manager at AMD Shanghai had listed the work on Project Greenland as a work experience highlight on his LinkedIn profile page. Greenland is described as “A leading chip of the first graphics IP v9.0 generation, it has full capacity of 4096 shader processor along with whole new SOC v15 architecture.”
The Graphics IP v9.0 designation is thought to signify a Vega GPU in the making. Zheng mentions this is an SOC, but then Hawaii and Fiji chips were described the same. Fiji is part of the graphics IP v8.0 family, as will be Polaris.
Vega following after Polaris, and designated as a ‘HMB2′ GPU by AMD, it looks like Vega based graphics cards will be the successors to the HBM equipped Fiji range such as the Radeon Fury and Nano. Fiju can manage 4096 stream processors, but with an upgrade to HBM2, 14nm process and other optimisation it is estimated that a Greenland/Vega GPU based graphics cards will offer 20 to 30 per cent better performance.
So with Greenland/Vega sporting HBM2 memory Hexus thinks that Polaris packing graphics cards will therefore feature GDDR5/X memory.

Russia Banking On Home Grown CPUs
A Russian firm announced its intention to build its own homegrown CPUs as part of a cunning plan to keep the Americans from spying on the glorious Empire of Tsar Putin and oil oligarchs.
Moscow Centre of SPARC Technologies (MCST) has announced it’s now taking orders for its Russian-made microprocessors from domestic computer and server manufacturers.
Dubbed the Elbrus-4C, it was fully designed and developed in MCST’s Moscow labs. It’s claimed to be the most high-tech processor ever built in Russia. They claim it is comparable with Intel’s Core i3 and Intel Core i5 processors, although they do not say what generation as one spec we found claimed it could manage a blistering 1.3 GHz which is slightly less than an average mobile phone.
MCST unveiled a new PC, the Elbrus ARM-401 which is powered by the Elbrus-4C chip and runs its own Linux-based Elbrus operating system. MCST claimed it can run Windows and Linux distributions. Yhe company has built a data centre server rack, the Elbrus-4.4, which is powered by four Elbrus-4C microprocessors and supports up to 384GB of RAM.
MCST said the Elbrus-4.4 is suitable for web servers, database servers, storage systems, servers, remote desktops and high-performance clusters.
Sergei Viljanen, editor in chief of the Russian-language PCWorld website said that the chip was at least five years behind the west.
“Russian processor technology is still about five years behind the west. Intel’s chips come with a 14nm design, whereas the Elbrus is 65 nm, which means they have a much higher energy consumption.”
MCST’s Elbrus-4C chips are powered by a 4-core processors, and come with an interface for hard drives and other peripherals. The company finalized development of Elbrus-4C in April 2014, and began mass production last autumn.
Will The Drupal Flaw Be Catastrophic?
Comments Off on Will The Drupal Flaw Be Catastrophic?
The Drupal web content management system has been exposed as having backdoor access that could deliver your site to hackers.
The problem is not particularly new. Drupal warned about it earlier this month, but it still needs tackling as millions of websites may be at risk.
Drupal said that sites running version 7 really ought to have upgraded to 7.32 by now, because not doing so leaves them as open as a torn tea bag.
Initially the alert was about the threat, but the firm has updated its earlier advice and is now warning of in-the-wild attacks.
That earlier advice was about a problem in a database API. “A vulnerability in this API allows an attacker to send specially crafted requests resulting in arbitrary SQL execution,” warned Drupal in a security alert.
“Depending on the content of the requests this can lead to privilege escalation, arbitrary PHP execution, or other attacks. This vulnerability can be exploited by anonymous users.”
More recent information from the firm points users toward the released upgrade, and informs them that attacks started not long after the initial announcement.
“You should proceed under the assumption that every Drupal 7 website was compromised unless updated or patched before Oct 15th, 11pm UTC, that is seven hours after the announcement,” it said, adding that, even when updated, sites will have some cleaning up to do.
“If you have not updated or applied this patch, do so immediately, then continue reading this announcement; updating to version 7.32 or applying the patch fixes the vulnerability but does not fix an already compromised website,” it explains.
“If you find that your site is already patched but you didn’t do it, that can be a symptom that the site was compromised – some attacks have applied the patch as a way to guarantee they are the only attacker in control of the site.”
Gavin Millard, EMEA technical director at Tenable Network Security, advised people to follow Drupal’s advice.
“The so-called ‘Drupageddon’ vulnerability could have easily led to exploitation of any systems running the vulnerable code. With such an easy to exploit flaw, the chance of exfiltration of data or further exploitation are high,” he said.
“For those who have good security controls, reviewing of logs and traffic directed at the sites following the vulnerability being announced and the patch applied is common sense and highly advisable, with appropriate action taken if indicators of compromise are found.
“For those who don’t have such a good level of security or visibility into the logs, the advice from the Drupal team should be heeded. If you don’t know if you were exploited you should assume that you have been.”
nVidia Releases CUDA
Nvidia has released CUDA – its code that lets developers run their code on GPUs – to server vendors in order to get 64-bit ARM cores into the high performance computing (HPC) market.
The firm said today that ARM64 server processors, which are designed for microservers and web servers because of their energy efficiency, can now process HPC workloads when paired with GPU accelerators using the Nvidia CUDA 6.5 parallel programming framework, which supports 64-bit ARM processors.
“Nvidia’s GPUs provide ARM64 server vendors with the muscle to tackle HPC workloads, enabling them to build high-performance systems that maximise the ARM architecture’s power efficiency and system configurability,” the firm said.
The first GPU-accelerated ARM64 software development servers will be available in July from Cirrascale and E4 Computer Engineering, with production systems expected to ship later this year. The Eurotech Group also plans to ship production systems later this year.
Cirrascale’s system will be the RM1905D, a high density two-in-one 1U server with two Tesla K20 GPU accelerators, which the firm claims provides high performance and low total cost of ownership for private cloud, public cloud, HPC and enterprise applications.
E4′s EK003 is a production-ready, low-power 3U dual-motherboard server appliance with two Tesla K20 GPU accelerators designed for seismic, signal and image processing, video analytics, track analysis, web applications and Mapreduce processing.
Eurotech’s system is an “ultra-high density”, energy efficient and modular Aurora HPC server configuration, based on proprietary Brick Technology and featuring direct hot liquid cooling.
Featuring Applied Micro X-Gene ARM64 CPUs and Nvidia Tesla K20 GPU accelerators, the new ARM64 servers will provide customers with an expanded range of efficient, high-performance computing options to drive compute-intensive HPC and enterprise data centre workloads, Nvidia said.
Nvidia added, “Users will immediately be able to take advantage of hundreds of existing CUDA-accelerated scientific and engineering HPC applications by simply recompiling them to ARM64 systems.”
ARM said that it is working with Nvidia to “explore how we can unite GPU acceleration with novel technologies” and drive “new levels of scientific discovery and innovation”.
nVidia Outs CUDA 6
Nvidia has made the latest GPU programming language CUDA 6 Release Candidate available for developers to download for free.
The release arrives with several new features and improvements to make parallel programming “better, faster and easier” for developers creating next generation scientific, engineering, enterprise and other applications.
Nvidia has aggressively promoted its CUDA programming language as a way for developers to exploit the floating point performance of its GPUs. Available now, the CUDA 6 Release Candidate brings a major new update in unified memory access, which lets CUDA applications access CPU and GPU memory without the need to manually copy data from one to the other.
“This is a major time saver that simplifies the programming process, and makes it easier for programmers to add GPU acceleration in a wider range of applications,” Nvidia said in a blog post on Thursday.
There’s also the addition of “drop-in libraries”, which Nvidia said will accelerate applications by up to eight times.
“The new drop-in libraries can automatically accelerate your BLAS and FFTW calculations by simply replacing the existing CPU-only BLAS or FFTW library with the new, GPU-accelerated equivalent,” the chip designer added.
Multi-GPU Scaling has also been added to the CUDA 6 programming language, introducing re-designed BLAS and FFT GPU libraries that automatically scale performance across up to eight GPUs in a single node. Nvidia said this provides over nine teraflops of double-precision performance per node, supporting larger workloads of up to 512GB in size, more than it’s supported before.
“In addition to the new features, the CUDA 6 platform offers a full suite of programming tools, GPU-accelerated math libraries, documentation and programming guides,” Nvidia said.
The previous CUDA 5.5 Release Candidate was issued last June, and added support for ARM based processors.
Aside from ARM support, Nvidia also improved Hyper-Q support in CUDA 5.5, which allowed developers to use MPI workload prioritisation. The firm also touted improved performance analysis and improved performance for cross-compilation on x86 processors.
nVidia Launching New Cards
We weren’t expecting this and it is just a rumour, but reports are emerging that Nvidia is readying two new cards for the winter season. AMD of course is launching new cards four weeks from now, so it is possible that Nvidia would try to counter it.
The big question is with what?
VideoCardz claims one of the cards is an Ultra, possibly the GTX Titan Ultra, while the second one is a dual-GPU job, the Geforce GTX 790. The Ultra is supposedly GK110 based, but it has 2880 unlocked CUDA cores, which is a bit more than the 2688 on the Titan.
The GTX 790 is said to feature two GK110 GPUs, but Nvidia will probably have to clip their wings to get a reasonable TDP.
We’re not entirely sure this is legit. It is plausible, but that doesn’t make it true. It would be good for Nvidia’s image, especially if the revamped GK110 products manage to steal the performance crown from AMD’s new Radeons. However, with such specs, they would end up quite pricey and Nvidia wouldn’t sell that many of them – most enthusiasts would probably be better off waiting for Maxwell.
MS Office Demand Fizzles
After a promising start, downloads of Microsoft’s free Office for the iPhone quickly nosedived, as the latest data from a mobile app analytics company showed.
But at least 200,000 copies of the small suite — iPhone versions of Word, Excel and PowerPoint — were downloaded in the first six days.
Distimo, a Dutch firm that tracks app store market data for several platforms, including Apple’s iOS, Google’s Android, and Microsoft’s Windows 8 and Windows Phone, said Office Mobile for the iPhone debuted in the No. 10 spot on June 15, the day after Microsoft launched the free app.
That was Office Mobile’s peak: On June 16, Office Mobile slipped to the No. 19 position among all free iPhone apps, then continued to slide throughout the week of June 17-23, starting that seven-day stretch at No. 36, falling to No. 86 by Friday, June 21, and ending at No. 299 on June 23.
From June 24 to July 6, Office Mobile was not on Distimo’s leaderboard, which lists only the top 400 downloaded apps.
The number of downloads of Office Mobile for iPhone is unknown — Distimo requires a paid account to show developers the estimated downloads of their apps and those of competitors, and did not reply to questions Sunday — but the tally was probably significant.
According to Distimo, to place in the App Store’s No. 10 spot, an app must average 72,000 downloads daily. Office Mobile was ranked No. 10 on June 15. Apps ranked at No. 50 averaged 23,000 downloads daily: Office Mobile held position at No. 50 or lower for five consecutive days.
Those numbers implied that at least 200,000 copies of Office Mobile were downloaded in the six days between June 15 and June 20.
Likewise, the sharp decline of Office Mobile’s position in the App Store’s free list after just a week hints at a pent-up demand that was quickly satisfied.
Although rumors of Office on iOS had circulated since the iPad’s 2010 introduction, they heated up last November when reports claimed Microsoft would launch a mobile version of the suite this year and tie the software to Office 365. At the time, most analysts agreed that Office 365 was the smart move because it could boost interest in the subscription concept Microsoft has bet will result in more, and more regular, revenue from its Office cash cow.
Linking Office on iOS to Office 365 would also let Microsoft avoid the Apple “tax,” the 30% cut that Apple takes from all App Store sales.
Only Office 365 subscribers can use Office Mobile. Subscriptions range from the consumer-grade Office 365 Home Premium, which costs $100 annually, to several business plans that start at $150 per user per year and climb to $264 per user per year.
