Today, Oculus VR issued a statement which claims that Michael Abrash has joined their ranks as Chief Scientist. Abrash was hired by Valve in 2011 where he led, and apparently came up with the idea for, their wearable computing initiatives. For a time, he and Jeri Ellsworth were conducting similar projects until she, and many others, were forced out of the company for undisclosed reasons (she was allowed to take her project with her which ultimately became CastAR). While I have yet to see an official announcement claim that Abrash has left Valve, I have serious doubts that he would be employed in both places for any reasonable period of time. With both gone, I wonder about Valve's wearable initaitive going forward.
Abrash at Steam Dev Days
This press statement comes just three days after Facebook announced "definitive" plans to acquire Oculus VR for an equivalent of $2 billion USD (it is twice the company Instragram was). Apparently, the financial stability of Facebook (... deep breath before continuing...) was the catalyst for this decision. VR research is expensive. Abrash is now comfortable working with them, gleefully expending R&D funds, advancing the project without sinking the ship.
And then there's Valve.
On last night's This Week in Computer Hardware (#260), Patrick Norton and I were discussing the Oculus VR acquisition. He claimed that he had serious doubts about whether Valve ever intended to ship a product. So far, the only product available that uses Valve's research is the Oculus Rift DK2. Honestly, while I have not really thought about it until now, it would not be surprising for Valve to contribute to the PC platform itself.
And, hey, at least someone is not afraid of Facebook's ownership.

Some lucky Aussies at The Register sweet talked their way into a Samsung Galaxy S5 and have put together a brief preview for your reading pleasure. There are many new features you will someday be able to use, even if El Reg couldn't quite test them yet. There is a battery saving mode which should help road warriors and a fingerprint sensor which is touted to work with NFC to turn your S5 into a replacement for your credit cards so you don't have to carry them with you. There is more to see in the article, including the Galaxy Gear Neo smartwatch.
"This time around Samsung is keen on its battery-saving mode, IP67 rating and, once again, fitness features. Samsung Australia personnel swore blind all of those features were designed for an “Aussie lifestyle”. Because down here we all go to the beach every day, a supposition only slightly less believable than the notion that an S5 design meeting considered how to optimise sales in a nation of 23 million."

The new Raidmax Cobra Power 500W PSU is actually a 6 year old RX-500AF with a new paintball splattered colour scheme. [H]ard|OCP felt that really showed when they looked at the power it delivers, a single 12V rail is our preference but the 384W max at 32A seems low compared to current 500W models on the market. That lack of power as well as other features which performed to specifications less than expected lead them to advise people to stay away from this PSU even with the attractively low price you will not be getting a great unit.
"We tread off the beaten PSU path today with a power supply from Raidmax that is part of the Cobra series. The RX-500AF-B unit sports 500 watts of "Haswell Ready" power, a Bronze efficiency rating, advertised stable voltages, a "strong single +12V rail for high-end system heavy load configuration," plus a paint ball stained exterior."

It is about time we took a look at AMD's new flagship processor, the A10-7850K Kaveri chip running at 3.7GHz or 4GHz at full boost with 4 Steamroller CPU cores and 8 Hawaii GPU cores. While we are still shy on HSA benchmarks at the moment, HiTech Legion did have a chance to do some Mantle testing with the APU alone and paired with a discrete GPU which showed off some of the benefits on Mantle. They also reached a decent overclock, a hair shy of 4.5GHz on air which is not too shabby for a processor that costs under $200. Check out the full review here.
"AMD has launched their fourth generation of APU, codenamed “Kaveri”. Kaveri boasts increased processor power coupled with advanced Radeon graphics but there are other technologies, such as HSA, that balance memory loads via “compute” to both the CPU and GPU."

Before we get to see Volta in action NVIDIA is taking a half step and releasing the Pascal architecture which will use Maxwell-like Streaming Multiprocessors and will introduce stacked or 3D memory which will reside on the same substrate as the GPU. Jen-Hsun claimed this new type of memory will vastly increase the bandwidth available, provide two and a half times the capacity and be four times as energy efficient at the same time. Along with the 3D memory announcement was the revealing of NVLink, an alternative interconnect which he claims will offer 5-12 times the bandwidth of PCIe and will be utilized by HPC systems. From his announcement that NVLink will feature eight 20Gbps lanes per block or as NVIDIA is calling them, bricks, which The Tech Report used to make a quick calculation and came up with an aggregate bandwidth of a brick of around 20GB/s. Read on to see what else was revealed.
"Today during his opening keynote at the Nvidia GPU Technology Conference, CEO Jen-Hsun Huang offered an update to Nvidia's GPU roadmap. The big reveal was about a GPU code-named Pascal, which will be a generation beyond the still-being-introduced Maxwell architecture in the firm's plans."

NVIDIA started the Emerging Companies Summit six years ago, and since then the event has grown in size and scope to identify and support those technology companies tha leverage (or plan to leverage) GPGPU computing to deliver innovative products. The ECS continues to be a platform for new startups to showcase their work at the annual GPU Technology Conference. NVIDIA provides support in the form of legal, developmental, and co-marketing to the companies featured at ECS.
There was an interesting twist this year though in the form of the Early Start Challenge. This is a new aspect to ECS in addition to the ‘One to Watch’ award. I attended the Emerging Companies Summit again this year and managed to snag some photos and participate in the Early Start Challenge (disclosure: i voted for Audiostream TV).
The 12 Early Start Challenge contestants take the stage at once to await the vote tally.
During the challenge, 12 selected startup companies were each given eight minutes on stage to pitch their company and why their innovations were deserving of the $100,000 grand prize. The on stage time was divided into a four minute presentation and a four minute Q&A session with the panel of judges (this year the audience was not part of the Q&A session at ECS unlike last year due to time constraints).
After all 12 companies had their chance on stage, the panel of judges and the audience submitted their votes for the most innovative startup. The panel of judges included:
- Scott Budman Business & Technology Reporter, NBC
- Jeff Herbst Vice President of Business Development, NVIDIA
- Jens Hortsmann Executive Producer & Managing Partner, Crestlight Venture Productions
- Pat Moorhead President & Principal Analyst, Moor Insights & Strategy
- Bill Reichert Managing Director, Garage Technology Ventures
The companies participating in the challenge include Okam Studio, MyCloud3D, Global Valuation, Brytlyt, Clarifai, Aerys, oMobio, ShiVa Technologies, IGI Technologies, Map-D, Scalable Graphics, and AudioStream TV. The companies are involved in machine learning, deep neural networks, computer vision, remote graphics, real time visualization, gaming, and big data analytics.
After all the votes were tallied, Map-D was revealed to be the winner and received a check for $100,000 from NVIDIA Vice President of Business Development Jeff Herbst.
Jeff Herbst awarding Map-D's CEO with the Early Start Challenge grand prize check. From left to right: Scott Budman, Jeff Herbst, and Thomas Graham.
Map-D is a company that specializes in a scaleable in-memory GPU database that promises millisecond queries directly from GPU memory (with GPU memory bandwidth being the bottleneck) and very fast database inserts. The company is working with Facebook and PayPal to analyze data. In the case of Facebook, Map-D is being used to analyze status updates in real time to identify malicious behavior. The software can be scaled across eight NVIDIA Tesla cards to analyze a billion Twitter tweets in real time.
It is specialized software, but extremely useful within its niche. Hopefully the company puts the prize money to good use in furthering its GPGPU endeavors. Although there was only a single grand prize winner, I found all the presentations interesting and look forward to seeing where they go from here.

Tagged: amd, firepro, W9100
The AMD FirePro W9100 has been announced, bringing the Hawaii architecture to non-gaming markets. First seen in the Radeon R9 series of graphics cards, it has the capacity for 5 TeraFLOPs of single-precision (32-bit) performance and 2 TeraFLOPs of double-precision (64-bit). The card also has 16GB of GDDR5 memory to support it. From the raw numbers, this is slightly more capacity than either the Titan Black or Quadro K6000 in all categories. It will also support six 4K monitors (or three at 60Hz), per card. AMD supports up to four W9100 cards in a single system.
Professional users can be looking for several things in their graphics cards: compute performance (either directly or through licensed software such as Photoshop, Premiere, Blender, Maya, and so forth), several high-resolution monitors (or digital signage units), and/or a lot of graphics performance. The W9100 is basically the top of the stack which covers all three of these requirements.
AMD also announced a system branding initiative called, "AMD FirePro Ultra Workstation". They currently have five launch partners, Supermicro, Boxx, Tarox, Silverdraft, and Versatile Distribution Services, which will have workstations available under this program. The list of components for a "Recommend" certification is: two eight-core 2.6 GHz CPUs, 32GB of RAM, four PCIe 3.0 x16 slots, a 1500W Platinum PSU, and a case with nine expansion slots (to allow four W9100 GPUs along with one SSD or SDI interface card).
Also, while the company has heavily discussed OpenCL in their slide deck, they have not mentioned specific versions. As such, I will assume that the FirePro W9100 supports OpenCL 1.2, like the R9-series, and not OpenCL 2.0 which was ratified back in November. This is still a higher conformance level than NVIDIA, which is at OpenCL 1.1.
Currently no word about pricing or availability.

Tagged: oculus rift, Kickstarter, john carmack, facebook
You've heard by now that Facebook has purchased Oculus and you likely have an opinion on the matter. There are quite a few issues this sale raises for the technologically inclined. For the Kickstarter backers, the question of the propriety of Vulture Capitalists benefiting monetarily from a project which began in part because of their donation made on Kickstarter; which still did net them a device. For those hoping that Oculus was going to be a project designed and lead by Palmer Luckey and involving John Carmack with little oversight or pressure from a company that wants an immediate return on their investment. For some the simple involvment of Facebook is enough to sour the entire deal regardless of any other factors.
KitGuru offers some possible benefits that could come of this deal; Facebook cannot afford to slow development as competitors such as castAR will soon arrive, nor can they really push Carmack around without risking his involvement. Before you start screaming take a moment to think about everything this deal involves and then express your opinion ... after all you don't get reality that is much more virtual than Facebook.
"I know guys. I know. I’m mad too. I’m sad, disappointed, even betrayed, but these are all things I’m feeling and I bet you are too. We’re having an emotional reaction to two companies worth multiple billions of dollars doing a business deal and though I can’t help but wish it hadn’t happened, I know that if I look at it logically, it makes sense for everyone."

Introduction and Features
The highly anticipated 450D mid-tower case is Corsair’s latest addition to their top of the line Obsidian Series and is the first new Obsidian case to be released in 2014. The Obsidian 450D mid-tower enclosure is positioned between Corsair’s 750D full-tower and 350D Micro-ATX enclosures and shares many of the same styling and design concepts of the 350D, 750D and 900D. The 450D is being introduced with an MSRP of $119.99 USD, which makes it considerably less expensive than Corsair’s classic Obsidian 650D mid-tower enclosure ($199.99 USD). It appears the new 450D may eventually become the successor to the 650D but we hope the 650D mid-tower case doesn’t go away any time soon as the two enclosures are still different enough to appeal to different users.

And in addition to PC enclosures, Corsair continues to offer one of the largest selections of memory products, SSDs, power supplies, coolers, gaming peripherals, and PC accessories currently on the market today!
Here is what Corsair has to say about the Obsidian 450D PC case:
“The 450D Performance Mid-Tower PC case matches the iconic, brushed aluminum design of the Obsidian series with an increased focus on high-airflow, ensuring your system not only looks great, but runs cool.
Behind the 450D’s aluminum mesh intake grill are dual AF140L intake fans to direct airflow straight to a PC’s hottest component, the graphics card. The rear AF120L 120mm fan keeps the airflow moving smoothly and five other optional fan locations give you serious cooling flexibility. The 450D’s fan mounts also accommodate a wide range of water-cooling radiators, with room for up to a 360mm radiator in the roof, a 280mm radiator in the front, and a 240mm radiator in the floor.
The 450D also boasts all of the features that make the Obsidian Series a favorite among enthusiasts around the world. Easily accessible dust filters on the roof, front, and bottom ensure your system will stay looking its best, while modular tool-free 3.5”/2.5” hard disk mounts offer a wide range of storage options, or can be removed entirely to prioritize airflow.”

Tagged: GTC 2014, tegra k1, nvidia, CUDA, kepler, jetson tk1, development
NVIDIA recently unified its desktop and mobile GPU lineups by moving to a Kepler-based GPU in its latest Tegra K1 mobile SoC. The move to the Kepler architecture has simplified development and enabled the CUDA programming model to run on mobile devices. One of the main points of the opening keynote earlier today was ‘CUDA everywhere,’ and NVIDIA has officially accomplished that goal by having CUDA compatible hardware from servers to desktops to tablets and embedded devices.
Speaking of embedded devices, NVIDIA showed off a new development board called the Jetson TK1. This tiny new board features a NVIDIA Tegra K1 SoC at its heart along with 2GB RAM and 16GB eMMC storage. The Jetson TK1 supports a plethora of IO options including an internal expansion port (GPIO compatible), SATA, one half-mini PCI-e slot, serial, USB 3.0, micro USB, Gigabit Ethernet, analog audio, and HDMI video outputs.
Of course the Tegra K1 part is a quad core (4+1) ARM CPU and a Kepler-based GPU with 192 CUDA cores. The SoC is rated at 326 GFLOPS which enables some interesting compute workloads including machine vision.
In fact, Audi has been utilizing the Jetson TK1 development board to power its self-driving prototype car (more on that soon). Other intended uses for the new development board include robotics, medical devices, security systems, and perhaps low power compute clusters (such as an improved Pedraforca system).It can also be used as a simple desktop platform for testing and developing mobile applications for other Tegra K1 powered devices, of course.
Beyond the hardware, the Jetson TK1 comes with the CUDA toolkit, OpenGL 4.4 driver, and NVIDIA VisionWorks SDK which includes programming libraries and sample code for getting machine vision applications running on the Tegra K1 SoC.
The Jetson TK1 is available for pre-order now at $192 and is slated to begin shipping in April. Interested developers can find more information on the NVIDIA developer website.

Tagged: gtx titan z, gtx titan, GTC 2014, CUDA
During the opening keynote, NVIDIA showed off several pieces of hardware that will be available soon. On the desktop and workstation side of things, researchers (and consumers chasing the ultra high end) have the new GTX Titan Z to look forward to. This new graphics card is a dual GK110 GPU monster that offers up 8 TeraFLOPS of number crunching performance for an equally impressive $2,999 price tag.
Specifically, the GTX TITAN Z is a triple slot graphics card that marries two full GK110 (big Kepler) GPUs for a total of 5,760 CUDA cores, 448 TMUs, and 96 ROPs with 12GB of GDDR5 memory on a 384-bit bus (6GB on a 384-bit bus per GPU). NVIDIA has yet to release clockspeeds, but the two GPUs will run at the same clocks with a dynamic power balancing feature. Four the truly adventurous, it appears possible to SLI two GTX Titan Z cards using the single SLI connector. Display outputs include two DVI, one HDMI, and one DisplayPort connector.
NVIDIA is cooling the card using a single fan and two vapor chambers. Air is drawn inwards and exhausted out of the front exhaust vents.
In short, the GTX Titan Z is NVIDIA's new number crunching king and should find its way into servers and workstations running big data analytics and simulations. Personally, I'm looking forward to seeing someone slap two of them into a gaming PC and watching the screen catch on fire (not really).
What do you think about the newest dual GPU flagship?

Tagged: shield, nvidia
The SHIELD from NVIDIA is getting a software update which advances GameStream, TegraZone, and the Android OS, itself, to KitKat. Personally, the GameStream enhancements seem most notable as it now allows users to access their home PC's gaming content outside of the home, as if it were a cloud server (but some other parts were interesting, too). Also, from now until the end of April, NVIDIA has temporarily cut the price down to $199.
Going into more detail: GameStream, now out of Beta, will stream games which are rendered on your gaming PC to your SHIELD. Typically, we have seen this through "cloud" services, such as OnLive and GaiKai, which allow access to a set of games that run on their servers (with varying license models). The fear with these services is the lack of ownership, but the advantage is that the slave device just needs enough power to decode an HD video stream.
In NVIDIA's case, the user owns both server (their standard NVIDIA-powered gaming PC, which can now be a laptop) and target device (the SHIELD). This technology was once limited to your own network (which definitely has its uses, especially for the SHIELD as a home theater device) but now can also be exposed over the internet. For this technology, NVIDIA recommends 5 megabit upload and download speeds - which is still a lot of upload bandwidth, even for 2014. In terms of performance, NVIDIA believes that it should live up to expectations set by their GRID. I do not have any experience with this, but others on the conference call took it as good news.
As for content, NVIDIA has expanded the number of supported titles to over a hundred, including new entries: Assassin's Creed IV, Batman: Arkham Origins, Battlefield 4, Call of Duty: Ghosts, Daylight, Titanfall, and Dark Souls II. They also claim that users can add other apps which are not officially supported, Halo 2: Vista was mentioned as an example, for streaming. FPS and Bitrate can now be set by the user. A bluetooth mouse and keyboard can also be paired to SHIELD for that input type through GameStream.
Yeah, I don't like checkbox comparisons either. It's just a summary.
A new TegraZone was also briefly mentioned. Its main upgrade was apparently its library interface. There has also been a number of PC titles ported to Android recently, such as Mount and Blade: Warband.
The update is available now and the $199 promotion will last until the end of April.

During the opening keynote of NVIDIA's GTC 2014 conference, company CEO Jen-Hsun Huang announced that Valve had ported the ever-popular "Portal" game to the NVIDIA SHIELD handheld gaming platform.
The game appeared to run smoothly on the portable device, and is a worthy addition to the catalog of local games that can be run on the SHIELD.
Additionally, while the cake may still be a lie, portable gaming systems apparently are not as Jen-Hsun Huang revealed that all GTC attendees will be getting a free SHIELD.

Users of Microsoft Word 2003 to the current version on PC or the 2011 version for Mac, which means any version of Outlook or other Microsoft application in which Word is the default text editor may want to avoid RTF attachments for the next while. There is an exploit in the wild which could allow a nefariously modified RTF file to give an attacker access to the machine which it was opened on at the same level as the user. This does mean that those who follow the advice of most Windows admins and do not log in to an administrator level account for day to day work need not worry overly but those who ignore the advice may find themselves compromised. As The Register points out, just previewing the attachment in Outlook is enough to trigger a possible infection.
"Microsoft has warned its Word software is vulnerable to a newly discovered dangerous bug – which is being exploited right now in "limited, targeted attacks" in the wild. There is no patch available at this time."

Gigabyte's Z87X-UD7-TH goes all out in terms of expansion slots with 5 PCIe 3.0 16x capable of running 4 cards at 8x simultaneously, along with two PCIe 2.0 1x slots in case you need even more cards to be plugged in. The Intel DSL5520 adds support for Thunderbolt 2 and there are 10 SATA 6Gbps ports, 10 USB 3.0 ports and even 4 legacy USB ports which should be enough for just about any user. Peripheral support is not everything though, find out about overclocking and stability under load in [H]ard|OCP's full review.
"We’ve covered a lot of budget motherboards lately and shown that you can get quite a lot for your dollar. The GIGABYTE motherboard we are looking at today is not a budget motherboard. In fact it’s on the complete opposite of the spectrum, competing with ASUS’ WS offerings and MSI’s Big Bang XPower series."

The Tech Report got their hands on the rather impressive Brix Pro from Gigabyte, a tiny PC that packs a fair amount of power. Hidden in this 2.4 x 4.3 x 4.5" box is a Core i7-4770R with accompanying HD 5200 Iris Pro graphics, a 240GB 525 Series SSD and 8GB of DDR3-1600, though the last two components are optional. The new Intel GPU was able to handle BF4 and Borderlands 2, though some strange artifacting was noticeable in the latter title. Overall they like the new Brix Pro but thought Gigabyte shrunk the device a little too much as the fan was quite loud when under load; a larger heatsink and fan combo may have avoided that minor irritation.
"The first, Intel-built NUC (short for Next Unit of Computing) debuted a little over a year ago, and our own Scott Wasson picked it apart at the time. Today, we're back with a mini-PC that's based on the same form factor but trades the power-sipping mobile CPU for a quad-core desktop specimen."
