Programmers are beginning to understand and be ever more comfortable with the uses of GPUs in their applications. Late last week we explored the KGPU project. KGPU is designed to allow the Linux kernel to offload massively parallel processes to the GPU to offload the CPU as well as directly increase performance. KGPU showed that in terms of an encrypted file system you can see whole multiple increases in read and write bandwidth on an SSD. Perhaps this little GPU thing can be useful for more? Alenka Project thinks so: they are currently working on a CUDA-based SQL-like language for data processing.
CUDA woulda shoulda... and did.
SQL databases are some of the most common methods to store and manipulate larger sets of data. If you have a blog it almost definitely is storing its information in a SQL database. If you play an MMO your data is almost definitely stored and accessed on a SQL server. As your data size expands and your number of concurrent accesses increases you can see why using a GPU could keep your application running much smoother.
Alenka in its current release supports large data sets exceeding both GPU and system RAM via streaming chunks, processing, and moving on. Its supported primitive types are doubles, longs, and varchars. It is open source under the Apache license V2.0. Developers interested in using or assisting with the project can check out their Sourceforge. We should continue to see more and more GPU-based applications appear in the near future as problems such as these are finally lifted from the CPU and given to someone more suitable to bear.
Gigabyte Launches World's First Z68 Motherboards With Support for mSATA Intel SLC SSDs and Smart Response Tech

Popular enthusiast motherboard maker Gigabyte has today announced 4 additional motherboards to their already expansive Z68 chipset based lineup at launch.
In addition to the features discussed in the previous announcement, including Lucid Virtu technology, the four new models feature a mSATA connection for onboard Intel SLC SSDs such as the new Intel 311 20GB SLC SSD. The 20GB drive can be used in conjunction with the Intel Smart Response Technology to boost system performance.
While Intel's SRT technology is also included in the other Gigabyte Z68 Motherboards, these 4 specific models differ in the implementation. Specifically, they allow consumers to attach the small solid state drive directly onto the motherboard. This will free the standard SATA ports of a SRT SSD for another hard drive or optical drive.
Gigabyte has found as much as a 471% improvement in PC Mark Vantage scores in using a 20GB Intel 311 SLC SSD and a SATA 2 hard drive versus solely a SATA 2 hard drive. PC Perspective also examined Intel's Smart Response Technology and found that in trace based testing, the SLC SSD greatly improved performance once the data had been cached to the SSD. As for improvements in boot performance, PC Perspective found that:
"Boot times were just 3 seconds shy of those achieved with the OS cached on the SSD entirely. Of significant note here is that the SSD 310 was able to edge out (0.5 secs) faster boot times than the SSD 320 *and* the SSD 510, which we tossed in for an additional point of comparison."
Intel's SRT technology can definitely improve performance in the right situations, and Gigabyte is offering even more options to implement it in their newly announced models; the Z68XP-UD3, Z68XP-D3, Z68AP-D3, and Z68P-DS3. The new models are due to be released in June 2011.

As further proof that no fairness exists in the universe, a lucky member of Rock, Paper, SHOTGUN has played the first 10 hours of Deus Ex:Human Revolution; not just once, but twice. If you played the first incarnation then you are probably terrified that it will follow the awful path of the sequel; unless you've taken the Highlander fan stance and pretend that it never happened. If you've only played the second ...
Anyways, head over as the news is not all bad, though the rampant cut scenes made the (p)reviewer want to do something that would effect his ability to reproduce rather than watch another one played.
"Because I am the luckiest man alive, I spent this weekend playing the first ten hours of Deus Ex: Human Revolution, which is starting to look like it’ll be the biggest release of 2011. When I finished those ten hours, I went back and played them again, and have finally managed to compress my thoughts into a handy list of thoughts that’ll occur to you, too, as you play. Five reasons to be hugely excited Deus Ex 3 and five reasons to be knuckle-chewingly nervous await you below."

The fourth Google I/O took place over the past two days and AnandTech was there to bear witness on the keynote speech and other presentations. As you might well expect Android was the most talked about, the new Honeycomb update was discussed in great detail and with good reason. The update allows Android powered devices to use USB peripherals in the same way as a PC, powering mice, keyboards and even XBox controllers which is a big change from only being able to be used as a USB device and offers even more for those interested in the Open Accessory Library.
Others will be more interested in Google's Music Beta which will let you upload your music collection to the web and includes the ability to make playlists and albums as well as gatherig meta artist information. You can think of it like Amazon's Cloud service, though hopefully more reliable, but as Google seems not to have got the permission of the record companies it may not be.
"Google’s I/O 2011 keynote may have suffered from a few choice leaks, namely the new Music service and Ice Cream Sandwich announcement, but Google still managed to include some surprises. Android 3.1, the update to Honeycomb, was announced along with a slew of development platforms, including one committed to bringing better introduction of accessories to Android devices of all types, and a home integration platform based on Android."

Tagged: UE3, graphics engine, gaming
Since 2006'a Gears of War, Epic Games' Unreal Engine 3 has provided both console and PC gamers hours of game play packed with graphical prowess. The now 5 year old graphics engine has enjoyed constant evolution to remain viable. At 2011's Games Developers Conference, Epic Games unvieled its Samaritan demo, proving to the world that not only could Unreal Engine 3 deliver graphics capable of fully utilizing current gen hardware but a huge evolution in graphical prowess that would require next gen hardware to in order to utilize all of it's features.
Using a three-way SLI GTX 580 powered gaming system, Epic Games was able to showcase some of the engine's newest features. Taking eight months of development, the engine contains a slew of lighting, reflection, and shadow improvements as well as realistic hair and cloth physics.
Bokeh Depth of Field has been a popular artistic choice in Hollywood Films for many years. Seen as out of focus but identifiable colored shapes in the background, bokeh objects serve to enhance a scene and influence viewers' moods. Epic was able to improve upon earlier methods of rendering bokeh objects, though they admit that real time rendering of bokeh objects as seen in Hollywood films will necessitate next gen hardware. Currently, the bokeh effects will be best used in cutscenes where developers can control and pre-render the objects to the best storytelling effect.
Epic has also greatly enhanced the ways that light and reflections are handled. Collectively called Image Based Reflections, Epic has implemented Point Light and Billboard Reflections. These are then coupled with both static and dynamic Reflection Shadows to achieve a look resembling the real world. While the graphics horsepower is not available today to allow Epic to mirror the way light works in the real world exactly, they are able to achieve a very close representation. For example, they are not able to render the road to be as detailed as real life. The road shown in their Samaritin demo was much less un-uniform. This is so because the hardware required to calculate reflections on a road as un-uniform as in real life (in real time) is simply not available today.

The last quarter of 2010 saw shipments totalling 18.84 million units. In 2011, shipments rose slightly by 2% to 19.03 million add-in cards. According to JPR (Jon Peddie Research), while Q1 of 2011 behaved similarly to past years seasonally, it did not fair as well overall as shipments did not exceed those of Q1 2010. Where AMD increased units shipped by 5.7% versus the previous quarter (Q4 2010), NVIDIA saw a 2% decrease.
JPR notes that while increase in units shipped versus Q4 2010 was rather slight, it remains a positive change due to Q4 2010 behaving irregularly regarding the seasonal cycle.
The increased units shipped further reflect changes in market share for the two largest discrete graphics card makers. Versus last quarter, NVIDIA lost 2.7% of the market while AMD gained 4.4%. JPR states that AMD has gained 16.6% market share while rival NVIDIA lost 8.4 on a year-to-year basis.
JRP's reported market shares over time.
John Peddie Research notes that of the 19.03 million discrete graphics cards shipped, NVIDIA was the clear market leader, thanks in part to sales of CUDA and GPU-Compute cards used in scientific and data research. The add-in board market is further composed of three main segments that amount to the 19.03 million boards shipped. On the high end rests the enthusiast gamer (approx. 9 million sold per year) and GPU-compute markets which exists as lower volume of sales but higher price per card. The majority of graphics card shipments come from the mainstream market which is a balance of price and volume. Finally, the workstation segment which is smaller than even the enthusiast gaming market but traditionally sees higher average asking prices for the hardware that is shipped.
JPR estimates that the add-in market will fall 4.5% to $19.8 billion USD despite positive increases in the number of cards shipped due to "a gradual decline in the ASP."
As the chart illustrates, NVIDIA still remains the market juggernaut, shipping 11.25 million cards; however, AMD has made a lot of headway in the past year. With both the AMD 6950 and Nvidia 560ti proving to be the cards of choice by many gamers worldwide competition is healthy and enthusiasts have only to benefit from the market's positive increases.

The rumour mill really dropped the ball on this one, as just a few hours ago it was Facebook that everyone was muttering would one day buy Skype. Turns out that in just a few hours the new rumour that Microsoft was going to buy Skype for $7 billion became a reality at an $8.5 billion price tag.
Skype lost $7 million dollars last year, though that number seems rather small compared to their overall balance sheet to date which puts them $686 million in the hole. As All Things Digital is quick to point out, that is slightly less than what Microsoft Online Services Division lost last Quarter, proving all things are relative even at very high amounts of dollars.
On the plus side, Microsoft gets its hands on Skype's 763 million registered users, about twice as many as there are MSN users and significantly more that there are XBox Live users. Toss in the TechNet people and you still have nowhere near the user pool that Skype brings. That huge increase in the number of people Microsoft can reach possibly gives them the ability to recoup the money they spent to buy them. Consider that 8 million users pay actual money for their Skype account, which Wired considers as at least a hint of Microsoft's strategy.
Most PC users who already use Windows, such as those at Ars Technica, are scratching their heads over the purchase while Linux users at Slashdot are very concerned about continuing support for the Skype Linux Client.
"The Wall Street Journal reported earlier tonight that Microsoft–in what would be its most aggressive acquisition in the digital space–was zeroing in on buying Skype for $8.5 billion all in with an assumption of the Luxembourg-based company’s debt.
Sources told BoomTown tonight that the deal for the online telephony and video communications giant is actually done and will be announced early tomorrow morning."

With the release of Ubuntu 11.04, a new desktop environment called Unity was released. Unity promised to revamp the Linux operating system’s desktop GUI to be more user friendly and intuitive. There are a multitude of noticeable changes that Unity brings to Ubuntu’s GUI compared to the classic Gnome environment. A new Windows 7 like task bar stretches along the left side of the screen where small icons of running and pinned applications reside. This new application dock is used instead of the traditional Gnome task bar that ran along the bottom of the screen. Also present is a new Ubuntu button that acts as an application launcher where installed programs can be sorted and searched for. Further, there are improvements to the workspace switcher and changes in window management with new hover-to-reveal scroll bars and each application’s (context sensitive) file menus being relocated to the top of the screen. These and other minor changes in the latest Ubuntu release have caused a flood of controversy among both reviewers and users alike.
Pictured: Unity GUI (Insert: Ubuntu Classic GUI)
On the positive side of the issue, there are a number of new and long time users of Ubuntu that have embraced the new GUI for it’s new features and design. Many people migrating from Windows 7 or Mac OS will become accustomed to the interface quickly as it works in much the same manner. Further, users of convertible tablet PCs have an easier time of navigating to applications and windows thanks to the larger icons. Touch and digitizer controls on the Dell Latitude XT worked well out of the box without a need to much with drivers, for example.
In contrast, as a newly developed desktop environment, it is less customizable from a user standpoint than the traditional Gnome GUI. Because of this (at the time of writing) restriction on customizability, many self-proclaimed power users have called Unity a step backwards in the aspects that make Linux a desirable OS--the ability to customize. Mainly, they dislike the constraints that Unity places on their ability to customize the operating system to their liking.

Tagged: IEEE, Ethernet
IEEE is a professional association known for creating technology standards, producing publications, and hosting activities both for educational and professional development. If you are browsing this website on a high speed connection you are almost definitely using IEEE 802.3 or IEEE 802.11 which are more commonly known as Ethernet and WIFI, respectively. IEEE constantly evolves their standards: speeds get faster, WIFI-n allowed you to leave 2.4 GHz, and other changes as needs progress over time.
Change for the future.
IEEE recently appointed John D’Ambrosia to chair a group to determine how much demand will be required from Ethernet in the future. This committee could potentially end up producing a standard for Terabit network connections should demand deem it necessary.
The committee is being very cautious this time around with respect to how much speed is required for their next standard. The prior standard, 802.3ab, was discussed in 2005 and determined that 100 Gbps was a necessary advancement. Later it was discovered that many vendors did not require more than 40 Gbps and would delay adoption for several years. Regardless of whether they settle on Terabit or 400 Gigabit, this standard will take years to develop with Terabit taking even longer. Their findings about demand will be published early next year.
