More Details Uncovered On AMD’s ZEN Cores

Our well informed industry sources have shared a few more details about the AMD’s 2016 Zen cores and now it appears that the architecture won’t use the shared FPU like Bulldozer.

The new Zen uses a SMT Hyperthreading just like Intel. They can process two threads at once with a Hyperthreaded core. AMD has told a special few that they are dropping the “core pair” approach that was a foundation of Bulldozer. This means that there will not be a shared FPU anymore.

Zen will use a scheduling model that is similar to Intel’s and it will use competitive hardware and simulation to define any needed scheduling or NUMA changes.

Two cores will still share the L3 cache but not the FPU. This because in 14nm there is enough space for the FPU inside of the Zen core and this approach might be faster.

We mentioned this in late April where we released a few details about the 16 core, 32 thread Zen based processor with Greenland based graphics stream processor.

Zen will apparently be ISA compatible with Haswell/Broadwell style of compute and the existing software will be compatible without requiring any programming changes.

Zen also focuses on a various compiler optimisation including GCC with target of SPECint v6 based score at common compiler settings and Microsoft Visual studio with target of parity of supported ISA features with Intel.

Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings.

We cannot predict any instruction per clock (IPC improvement) over Intel Skylake, but it helps that Intel replaced Skylake with another 14nm processor in later part of 2016. If Zen makes to the market in 2016 AMD might have a fighting chance to narrow the performance gap between Intel greatest offerings.

Dropbox Beefs Up Security

Two-factor authentication is widely regarded as a best practice for security in the online world, but Dropbox has announced a new feature that’s designed to make it even more secure.

Whereas two-step verification most commonly involves the user’s phone for the second authentication method, Dropbox’s new U2F support adds a new means of authenticating the user via Universal 2nd Factor (U2F) security keys instead.

What that means is that users can now use a USB key as an additional means to prove who they are.

“This is a very good advancement and adds extra security over mobile notifications for two-factor authentication,” said Rich Mogull, Securosis CEO.

“Basically, you can’t trick a user into typing in credentials,” Mogull explained. “The attacker has to compromise the exact machine the user is on.”

For most users, phone-based, two-factor authentication is “totally fine,” he said. “But this is a better option in high-security environments and is a good example of where the FIDO standard is headed.”

Security keys provide stronger defense against credential-theft attacks like phishing, Dropbox said.

“Even if you’re using two-step verification with your phone, some sophisticated attackers can still use fake Dropbox websites to lure you into entering your password and verification code,” the company explained in a blog post. “They can then use this information to access your account.”

Security keys, on the other hand, use cryptographic communication and will only work when the user is signing in to the legitimate Dropbox website.

Dropbox users who want to use the new feature will need a security key that follows the FIDO Alliance’s Universal 2nd Factor (U2F) standard. That U2F key can then be set up with the user’s Dropbox account along with any other U2F-enabled services, such as Google.

AMD Coherent Data Reaches 100 GBs

After a lot of asking around, we can give you some actual numbers about the AMD’s coherent fabric.

The inter-connecting technology already sounded very promising, but now we have the actual number. The HSA, Heterogeneous System Architecture MCM (Multi Chip Module) that AMD is working on can give you almost seven times faster score than the traditional PCIe interface.

Our industry sources have confirmed that with 4 GMI (Global Memory Interconnect) links AMD’s CPU and GPU can talk at 100GB/s. the traditional PCIe 16X provides 15GB/s at about 500 ns latency. Data Fabric eliminates PCIe latency too.

AMD will be using this technology with the next gen Multi Chip module that packs a Zeppelin CPU (most likely packed with a bunch of ZEN cores) and a Greenland GPU that of course comes with super fast HBM (High Bandwidth Memory). The Greenland and HBM can communicate at 500 GB/s and can provide highest performance GPU with 4+ teraflops.

This new MCM package based chip will also talk with DDR4 3200 memory at 100GB/s speed making it quite attractive for the HSA computation oriented customers.

Will Qualcomm Unveil The Snapdragon 820 SoC

Qualcomm is set to unveil its new Snapdragon 820 SoC on August 11 in LA and more details are being leaked than you would see at a Welsh leak recipe contest.

It appears that the new Snapdragon 820 will have the catchy title MSM8996 and it promises some significant performance improvements in key areas. We already know that it will not be catching fire, but it also has a 40 per cent GPU performance increase with its A530 GPU.

The device is also claimed to have a 30 per cent power improvement with 64b of shared virtual memory with the CPU.

Another big area of improvement is the Hydra CPU, which claims a 35 percent improvement compared to the Snapdragon 810.

The Snapdragon 820 will support 4k60 entertainment and high-speed data connectivity.

There are rumours that there will be a QFE3100 Envelope Tracking system this will not speed up mail in the criminally slow Italian Post Office, but should create a lower power and a thermal footprint. A dedicated low power sensor is integrated for always on use.

Another major upgrade compared to the older SoC is a switch from 20nm to 14nm FinFET manufacturing process. We are still expecting the Xiaomi Mi5 to be the first one to use it.

Oracle’s New Processor Goes For The Cheap

Oracle is looking to expand the market for its Sparc-based servers with a new, low-cost processor which it curiously called Sonoma.

The company isn’t saying yet when the chip will be in the shops but the spec shows that could become a new rival for Intel’s Xeon chips and make Oracle’s servers more competitive.

Sonoma is named after a place where they make cheap terrible Californian wine  and Oracle aims the chip at Sparc-based servers at “significantly lower price points” than now.

This means that companies can use them for smaller, less critical applications.

Oracle has not done much with its Sparc line-up for a couple of years, and Sonoma was one of a few new chips planned. The database maker will update its Sparc T5, used in its mid-range systems and the high-end Sparc M7. The technology is expected to filter to the Sonoma lower tier servers.

The Sparc M7 will have technologies for encryption acceleration and memory protection built into the chip. It will include coprocessors to speed up database performance.

According to IDG Sonoma will take those same technologies and bring them down to low-cost points. This means that people can use them in cloud computing and for smaller applications.

He didn’t talk about prices or say how much cheaper the new Sparc systems will be, and it could potentially be years before Sonoma comes to market.

Can OSX Make Macs Vulnerable To Rootkits?

The software genii at Apple have redesigned their OSX software to allow malware makers to make designer micro-software that can infect Macs with rootkits.

Obviously the feature is one that Apple software experts designed specifically for malware writers, perhaps seeing them as an untapped market.

The bug in the latest version of Apple’s OS X allows attackers root user privileges with a micro code which could be packed into a message.

Security researcher Stefan Esser said that this was the security hole attackers regularly exploit to bypass security protections built into modern operating systems and applications.

The OS X privilege-escalation flaw stems from new error-logging features that Apple added to OS X 10.10. Plainly the software genii did not believe that standard safeguards involving additions to the OS X dynamic linker dyld applied to them because they were protected from harm by Steve Job’s ghost.

This means that attackers to open or create files with root privileges that can reside anywhere in the OS X file system.

“This is obviously a problem, because it allows the creation or opening (for writing) of any file in the filesystem. And because the log file is never closed by dyld and the file is not opened with the close on exec flag the opened file descriptor is inherited by child processes of SUID binaries. This can be easily exploited for privilege-escalation,” Esser said.

The vulnerability is present in both the current 10.10.4 (Yosemite) version of OS X and the current beta version of 10.10.5. Importantly, the current beta version of 10.11 is free of the flaw, an indication that Apple developers may already be aware of the vulnerability.

An Apple spokesman said that engineers are aware of Esser’s post of course they did not say they would do anything about it. They will have to go through the extensional crisis involved in realising that their product was not secure or perfect. Then the security team will have to issue orders, signed in triplicate, sent in, sent back, queried, lost, found, subjected to an internal inquiry, lost again, and finally bury it in soft peat for three months and recycled as firelighters.

Microsoft Unveils ‘Send’ Mobile App

Microsoft unveiled a mobile-minded alternative to email that’s focused primarily on short, quick messages.

Named Send, the new tool aims to deliver a simple experience much like that offered by text messaging or instant messaging software but without the need to know a co-worker’s mobile number or username. Instead, Send lets users quickly fire off a message to any co-worker using just their email address; no subject line, salutations or signatures are required.

“On my way,” might be one example, or “Are you in the office today?”

The app connects to Office 365 business and school email accounts to find frequent and recent contacts; users need only tap on one to start a conversation. A “Quick Reply” option allows for speedy responses.

That Office 365 connection, meanwhile, also means conversations are synced with Outlook, letting users continue them from anywhere. Messages sent using Send are treated internally like any other work email and comply with an organization’s email compliance policies, Microsoft said.

Send is now available free for iPhone through the Microsoft Garage in the U.S. and Canada. Versions for Windows Phone and Android are coming soon, as are additional IT controls. Currently the app works with Office 365 business and school email accounts, but Microsoft plans to make it more broadly available in the coming months, it said.

Microsoft To Open Source Radio Code

Microsoft has begun to open source some more of its code, this time for the Microsoft Research Software Radio (Sora).

“We believe that a fully open source Sora will better support the research community for more scientific innovation,” said Kun Tan, a senior researcher on the Sora project team.

Sora was created to combat the problem of creating software radio that could keep up with the hardware developments going on around it.

The idea behind it is to run the radio off software on a multi-core PC running a basic operating system. In the example, it uses Windows. But then it would.

A PCIe radio control board is added to the machine with signals processed by the software for transmission and reception, while the RF front-end, with its own memory, interfaces with other devices.

The architecture also supports parallel processing by distributing processing pipelines to multiple cores exclusively for real-time SDR tasks.

Sora has already won a number of awards, and the Sora SDK and API were released in 2011 for academic users. More than 50 institutions now use it for research or courses.

As such, and in line with the groovy open Microsoft ethos, the software has now been completely open sourced, with customizable RF front-ends, customizable RCB with timing control and synchronization, processing accelerators and support for new communication models such as duplex radios.

The Sora source code is now up on GitHub. Use cases already in place include TV whitespace, large scale MIMO and distributed MIMO systems.

Microsoft has made a number of moves towards open sourcing itself over the past year. Most notably, The .NET Framework at the heart of most Windows programs was offered up to the newly created .NET Foundation.

It was announced yesterday that Google is releasing its Kubernetes code to the Linux Foundation to set up a standardized format for containerization.

AMD Misses Again

Fabless chipmaker AMD has come up with a mixed set of results for the second quarter. The company managed to make as much cash as the cocaine nose jobs of Wall Street expected, but missed revenue expectations.

In fact its revenues were below the psychologically important billion figure at $942 million.

We knew it was going to be bad. Last week we were warned that the results would be flat. The actual figure was $942m, an 8.5 per cent sequential decline and a 34.6 per cent drop from the same period a year ago.

As you might expect, there are some measures of this not being AMD’s fault. The company is almost entirely dependent on PC sales. Not only have these fallen but don’t look like they are going to pick up for a while.

AMD’s Computing and Graphics division reported revenue of $379m, which was down 54.2 per cent, year-on-year. Its operating loss was $147m, compared to a $6m operating loss for last year’s quarter.

Lisa Su, AMD president and CEO, in a statement said that strong sequential revenue growth in AMD’s enterprise, embedded, and semi-custom segment and channel business was not enough to offset near-term problems in its PC processor business.  This was  due to lower than expected consumer demand that impacted sales to OEMs, she said.

“We continue to execute our long-term strategy while we navigate the current market environment. Our focus is on developing leadership computing and graphics products capable of driving profitable share growth across our target markets,” she added.

In the semi-custom segment, AMD makes chips for video game consoles such as the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles. That segment did reasonably well, up 13 percent from the previous quarter but down 8 percent from a year ago.

But AMD’s core business of processors and graphics chips fell 29 percent from the previous quarter and 54 percent from a year ago. AMD said it had decreased sales to manufacturers of laptop computers.

Figures like this strap a large target on AMD’s back with a sign saying “take me over” but AMD is not predicting total doom yet.

For the third quarter, AMD expects revenue to increase 6 percent, plus or minus 3 percent, sequentially, which is a fairly conservative outlook given the fact that Windows 10 is expected to push a few sales its way.

AMD supplies chips to the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles and these seem to be going rather well.

Darkode Hacking Forum Shut Down

Law enforcement agencies from 20 countries collaborated to cripple a major computer hacking forum, and U.S. officials filed criminal charges against a dozen people associated with the website, the U.S. Department of Justice announced.

Darkode.com on is displaying a message saying the site and domain had been seized by the FBI and other law enforcement agencies.

Darkode, a password-protected online forum for criminal hackers, represented one of the gravest threats to the integrity of data on computers across the world, according to David Hickton, U.S. attorney for the Western District of Pennsylvania. “Through this operation, we have dismantled a cyber hornets’ nest of criminal hackers which was believed by many, including the hackers themselves, to be impenetrable.”

Five of the defendants face charges in Hickton’s district.

Darkode allowed hackers and other cybercriminals to sell, trade and share information and tools related to illegal computer hacking, the law enforcement agencies alleged.

Before becoming a member of Darkode, prospective participants were allegedly vetted through a process that included an invitation by a member, the DOJ said in a press release. The prospective member then pitched the skill or products he or she could bring to the forum.

Darkode members allegedly used each other’s skills and products to infect computers and electronic devices of victims around the world with malware, the DOJ said.

The takedown of the forum and the charges announced Wednesday came after the FBI’s infiltration of Darkode’s membership.
