Tagged: SYCL, opencl, gdc 14, GDC
To gather community feedback, the provisional specification for SYCL 1.2 has been released by The Khronos Group. SYCL extends itself upon OpenCL with the C++11 standard. This technology is built on another Khronos platform, SPIR, which allows the OpenCL C programming language to be mapped onto LLVM, with its hundreds of compatible languages (and Khronos is careful to note that they intend for anyone to make their own compatible alternative langauge).
In short, SPIR allows many languages which can compile into LLVM to take advantage of OpenCL. SYCL is the specification for creating C++11 libraries and compilers through SPIR.
As stated earlier, Khronos wants anyone to make their own compatible language:
While SYCL is one possible solution for developers, the OpenCL group encourages innovation in programming models for heterogeneous systems, either by building on top of the SPIR™ low-level intermediate representation, leveraging C++ programming techniques through SYCL, using the open source CLU libraries for prototyping, or by developing their own techniques.
SYCL 1.2 supports OpenCL 1.2 and they intend to develop it alongside OpenCL. Future releases are expected to support the latest OpenCL 2.0 specification and keep up with future developments.
The SYCL 1.2 provisional spec is available at the Khronos website.

Tagged: OpenGL ES, opengl, Khronos, gdc 14, GDC
Today, day one of Game Developers Conference 2014, the Khronos Group has officially released the 3.1 specification for OpenGL ES. The main new feature, brought over from OpenGL 4, is the addition of compute shaders. This opens GPGPU functionality to mobile and embedded devices for applications developed in OpenGL ES, especially if the developer does not want to add OpenCL.
The update is backward-compatible with OpenGL ES 2.0 and 3.0 applications, allowing developers to add features, as available, for their existing apps. On the device side, most functionality is expected to be a driver update (in the majority of cases).
OpenGL ES, standing for OpenGL for Embedded Systems but is rarely branded as such, delivers what they consider the most important features from the graphics library to the majority of devices. The Khronos Group has been working toward merging ES with the "full" graphics library over time. The last release, OpenGL ES 3.0, was focused on becoming a direct subset of OpenGL 4.3. This release expands upon the feature-space it occupies.
OpenGL ES also forms the basis for WebGL. The current draft of WebGL 2.0 uses OpenGL ES 3.0 although that was not discussed today. I have heard murmurs (not from Khronos) about some parties pushing for compute shaders in that specification, which this announcement puts us closer to.
The new specification also adds other features, such as the ability to issue a draw without CPU intervention. You could imagine a particle simulation, for instance, that wants to draw the result after its compute shader terminates. Shading is also less rigid, where vertex and fragment shaders do not need to be explicitly linked into a program before they are used. I inquired about the possibility that compute devices could be targetted (for devices with two GPUs) and possibly load balanced, in a similar method to WebCL but no confirmation or denial was provided (although he did mention that it would be interesting for apps that fall somewhere in the middle of OpenGL ES and OpenCL).
The OpenGL ES 3.1 spec is available at the Khronos website.

Tagged: GDC, gdc 14, valve, Steam Controller
Two months ago, Valve presented a new prototype of their Steam Controller with a significantly changed button layout. While the overall shape and two thumbpads remained constant, the touchscreen disappeared and the face buttons more closely resembled something from an Xbox or PlayStation. Another prototype image has been released, ahead of GDC, without many changes.
Valve is still in the iteration process for its controller, however. Ten controllers will be available at GDC, each handmade. This version has been tested internally for some undisclosed amount of time, but this will be the first time that others will give their feedback since the design that was shown at CES. The big unknown is: to what level are they going to respond to feedback? Are we at the stage where it is about button sizing? Or, will it change radically - like to a two-slice toaster case with buttons inside the slots.
GDC is taking place March 17th through the 21st. The expo floor opens on the 19th.

Tagged: gdc 14, crytek, CRYENGINE
The Game Developers Conference (GDC 2014) is getting set for next week in San Francisco and Crytek has an early announcement. Attendees of the event, at presentations and demos in their booth, will see CRYENGINE running natively on Linux. The engine has also been updated to include their enhancements first seen in Ryse, such as "Physically Based Shading".
This announcement gives promise to SteamOS as a viable gaming platform because games which license this engine would have an easier time porting over. That said, Unreal Engine has offered Linux compatibility for licensees, to very limited uptake. Sure, Steam could change that trend because a chicken or an egg could happen at some point -- it does not matter which comes first. Still, this is not the first popular engine to be available for Linux.
Their "Physically Based Shading" system is quite interesting, however. As I understand it, the idea is that developers can make (or maybe use) a library of materials and apply it across any game. This should hopefully reduce the number of artist man-hours to produce a generalized optimal shader. It is much slower to tweak specular highlights and vector math than it is to say "you... are gold... be gold".
The official GDC expo will take place March 19th - 21st but I expect news will flood out from now until then.

Tagged: qualcomm, nvidia, microsoft, Intel, gdc 14, GDC, DirectX 12, amd
The announcement of DirectX 12 has been given a date and time via a blog post on the Microsoft Developer Network (MSDN) blogs. On March 20th at 10:00am (I assume PDT), a few days into the 2014 Game Developers Conference in San Francisco, California, the upcoming specification should be detailed for attendees. Apparently, four GPU manufacturers will also be involved with the announcement: AMD, Intel, NVIDIA, and Qualcomm.
As we reported last week, DirectX 12 is expected to target increased hardware control and decreased CPU overhead for added performance in "cutting-edge 3D graphics" applications. Really, this is the best time for it. Graphics processors are mostly settled into highly-efficient co-processors of parallel data, with some specialized logic for geometry and video tasks. A new specification can relax the needs of video drivers and thus keep the GPU (or GPUs, in Mantle's case) loaded and utilized.
But, to me, the most interesting part of this announcement is the nod to Qualcomm. Microsoft values DirectX as leverage over other x86 and ARM-based operating systems. With Qualcomm, clearly Microsoft believes that either Windows RT or Windows Phone will benefit from the API's next version. While it will probably make PC gamers nervous, mobile platforms will benefit most from reducing CPU overhead, especially if it can be spread out over multiple cores.
Honestly, that is fine by me. As long as Microsoft returns to treating the PC as a first-class citizen, I do not mind them helping mobile, too. We will definitely keep you up to date as we know more.

Also at Mobile World Congres, Lenovo expanded their smartphone portfolio with three additions. Each of these belong to the S-series, although they are only loosely related to one another. North American readers will probably not be able to purchase them, of course; Lenovo's US and Canada websites do not even have a section for smartphones (products like the Vibe Z can be searched directly - but are not available). I take that as a sign.
Anyway, the three phones belong to the S-series but each has a distinct customer in mind. The S860 seems to picture a business user who travels and wants to talk for long periods of time between charges. The similarly named S850 cuts back on RAM and charge capacity, replacing it with aesthetics (colors and an all-glass exterior) and a slightly lower price for users looking for design. Finally, the S660 is the lowest-price of the three, sacrificing things like camera, storage, and screen resolution for users who do not care about any of that.
Let us compare the three phones in a table.
|Display||5.3" 720p||5" 720p||4.7" 960x540|
|Processor (SoC)||MediaTek Quad-Core, 1.3 GHz|
|Dual SIM Card||Yes|
All three phones will be available this year, either at retail or on Lenovo's website. The Lenovo S860 is expected to retail for $349, the S850 should be $269, and the S660 comes in at $229.

Tagged: tablet, MWC 14, MWC, lenovo yoga, Lenovo
At Mobile World Congress 2014, Lenovo has announced the YOGA Tablet 10 HD+. Just last month, we discussed the Yoga Tablet 8 and Yoga Tablet 10 which were presented in October. Those tablets each had a 1280x800 display (even the 10-inch model), both sizes use the same MediaTek MT8125 SoC (Wi-Fi, MT8389 for 3G), and it is 1GB of RAM all-around. Performance was expected to be in the ballpark of a Tegra 3 device.
These are all areas which are bumped for the new YOGA Tablet 10 HD+. The 10.1-inch screen is now at 1080p quality, the SoC is a Qualcomm Snapdragon Quad running at 1.8 GHz, and the RAM is doubled to 2GB. It will running Android 4.3 with an alleged over-the-air (OTA) update to 4.4 KitKat, at some point.
Make sure to bend at the knee and put your hands toge... oh right.
Comparing between the Yoga Ultrabooks, running Windows, and the YOGA Tablets, running Android, would probably not be wise. They are very different designs. The Ultrabooks hinge with an always-attached keyboard while the tablets have a keyboard-less stand. Rather than the Ultrabooks trying to make a keyboard comfortable in tablet usage, the tablets use the small metal hinge to prop up the screen. They key aspect of the cylindrical hinge is its usage as a handle and the volume it provides as battery storage. Ryan found the old versions' 18-hour rated battery life to be fairly accurate, and the new 10 HD+ is rated for the same duration (actually, with a bonus 1000 mAh over the original Tablet 10). Another benefit of its battery location is that, if you are holding the tablet by its hinge, the battery's weight will not have much torque on your fingers.
Of course, now comes the all-important pricing and availability. The Lenovo YOGA Tablet 10 HD+ will be released in April starting at $349. This is higher than the prices of the Tablet 8 and Tablet 10, $199 and $274 respectively, but you also get more for it.

Valve has always been a company based on experimentation and it looks like the Steam Controller is not the lighthouse which guides SteamOS through the fog. Just a week after presenting the prototype at CES, a 3D mockup of a new one makes not-insignificant changes. Gone is the touchscreen and the first revealed button placement. Frankly, just about the only things untouched on the front face are the twin touchpads and the palm grips.
Image Credit: Leszek Godlewski (Twitter)
To fully understand the breadth of the changes, the announcement image is included below. There is basically no discussion about the back so that aspect might be untouched.
The changes were apparently made to assist compatibility with games ported from more traditional input schemes. Looking at the original prototype, there was no obvious mapping from a Sony or Microsoft-based controller to those buttons spread out for both the left and right thumbs to access. The new setup is the typical four face buttons on the right and four more buttons on the left as a surrogate directional pad. If they continue to iterate down this path I hope that the directional pad is more effective than most from the last two generations. It looks like the four directions are separated from one another which does not inspire confidence.
There are two stories which entangle on this one. The first is that Valve is willing to perform rapid iteration until they achieve what they consider a maximum. That is the method to quickest success especially since it allows cross-pollination between designs.
The second is that it also makes the public a little bit nervous.
