Tagged: WebCL, gdc 14, GDC
The Khronos Group has just ratified the standard for WebCL 1.0. The API is expected to provide a massive performance boost to web applications which are dominated by expensive functions which can be offloaded to parallel processors, such as GPUs and multi-core CPUs. Its definition also allows WebCL to communicate and share buffers between it and WebGL with an extension.
Frequent readers of the site might remember that I have a particular interest in WebCL. Based on OpenCL, it allows web apps to obtain a list of every available compute device and target it for workloads. I have personally executed tasks on an NVIDIA GeForce 670 discrete GPU and other jobs on my Intel HD 4000 iGPU, at the same time, using the WebCL prototype from Tomi Aarnio of Nokia Research. The same is true for users with multiple discrete GPUs installed in their system (even if they are not compatible with Crossfire, SLi, or are from different vendors altogether). This could be very useful for physics, AI, lighting, and other game middleware packages.
Still, browser adoption might be rocky for quite some time. Google, Mozilla, and Opera Software were each involved in the working draft. This leaves both Apple and Microsoft notably absent. Even then, I am not sure how much interest exists within Google, Mozilla, and Opera to take it from a specification to a working feature in their browsers. Some individuals have expressed more faith in WebGL compute shaders than WebCL.
Of course, that can change with just a single "killer app", library, or middleware.
I do expect some resistance from the platform holders, however. Even Google has been pushing back on OpenCL support in Android, in favor of their "Renderscript" abstraction. The performance of a graphics processor is also significant leverage for a native app. There is little, otherwise, that cannot be accomplished with Web standards except a web browser itself (and there is even some non-serious projects for that). If Microsoft can support WebGL, however, there is always hope.
The specification is available at the Khronos website.

The Khronos Group has also released their ratified specification for EGL 1.5. This API is at the center of data and event management between other Khronos APIs. This version increases security, interoperability between APIs, and support for many operating systems, including Android and 64-bit Linux.
The headline on the list of changes is the move that EGLImage objects makes, from the realm of extension into EGL 1.5's core functionality, giving developers a reliable method of transferring textures and renderbuffers between graphics contexts and APIs. Second on the list is the increased security around creating a graphics context, primarily designed for WebGL applications which any arbitrary website can become. Further down the list is the EGLSync object which allows further partnership between OpenGL (and OpenGL ES) and OpenCL. The GPU may not need CPU involvement when scheduling between tasks on both APIs.
During the call, the representative also wanted to mention that developers have asked them to bring EGL back to Windows. While it has not happened yet, they have announced that it is a current target.
The EGL 1.5 spec is available at the Khronos website.

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.

Back in January I wrote a short editorial that asked the question: "Is now the time to buy an SSD?" At that time we were looking at a combination of price drops with a lack of upcoming hardware releases. Since that published we have seen the release of the Intel 730 Series SSDs and even the new Crucial M550. While those are interesting drives to be sure (review pending on the M550), they aren't changing our opinions on the currently available, and incredibly cheap, solid state options.
While looking for some new hardware for the office, I found that the 1TB Samsung 840 EVO is now at an all time low $469! That is one of the faster SSDs on the market, and one of Allyn's favorites, for $0.469/GB!! I have included an updated table below with some of the most popular SSDs and their prices.
|Samsung 840 EVO||120 GB||$0.69/GB||$83 - Amazon|
|250 GB||$0.55/GB||$139 - Amazon|
|500 GB||$0.51/GB||$259 - Amazon|
|750 GB||$0.51/GB||$388 - Amazon|
|1000 GB||$0.46/GB||$469 - Amazon|
|Samsung 840 Pro||128 GB||$0.92/GB||$119 - Amazon|
|256 GB||$0.77/GB||$199 - Amazon|
|512 GB||$0.74/GB||$413 - Amazon|
|Intel 530 Series||120 GB||$0.91/GB||$89 - Amazon|
|180 GB||$0.80/GB||$144 - Amazon|
|240 GB||$0.62/GB||$149 - Amazon|
|480 GB||$0.87/GB||$419 - Amazon|
|Crucial M500 Series||120 GB||$0.57/GB||$69 - Amazon|
|240 GB||$0.49/GB||$119 - Amazon|
|480 GB||$0.47/GB||$229 - Amazon|
|960 GB||$0.45/GB||$439 - Amazon|
The biggest price drops were seen in the higher capacity drives including, the Samsung 840 EVO 1TB and 750GB models, the Intel 530 Series 480GB drive and even the Crucial M500 960GB and 480GB drives. Numerically the best value is with the 960GB Crucial M500 drive at $0.45/GB but it is followed very closely by that 1TB Samsung 840 EVO.
As of now, the Intel 730 Series of SSDs is available for sale on Amazon.com but their price per GB comparisons don't really match that of the EVO or M500. They are great drives, just read Allyn's review to see the proof of that, but they are targeted at the very performance conscious. The Crucial M550 is brand new, and looks interesting; expect us to dive more into that line very soon.
For me personally, grabbing a 750GB SSD is incredibly enticing and I think I'll find a handful in my cart to update our older 180GB SSD test beds.

The root DNS of the internet has been run by National Telecommunications and Information Administration, a division of of the US Government though in truth they contracted out this responsibility to the non-profit Internet Corporation for Assigned Names and Numbers and their Internet Assigned Numbers Authority. This will not really change much in the way that the root DNS has handled but is more a handover of official responsibility as the US Government hands off it's past role as overseer of the internet. If ICANN and IANA are unfamiliar to you then pop over to The Register for a very brief overview of what they actually do.
"The US Department of Commerce is ready to leave the keys to the internet's worldwide DNS system in the hands of non-profit net overseer ICANN."

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.

We know that SSD's help any system perform better by reducing the storage bottlenecks we all experienced from hard disk drives. But how far can flash storage go in increasing performance if money is no object?? Enter the multi-million dollar world of supercomputers. Historically supercomputers have relied on the addition of more CPU cores to increase performance, but two new system projects funded by the National Science Foundation (NSF) will try a different approach: obscene amounts of high-speed flash storage!
The news comes as the NSF is requesting a cool $7 billion in research money for 2015, and construction has apparently already begun on two new storage-centered supercomputers. Memory and high-speed flash storage arrays will be loaded on the Wrangler supercomputer at Texas Advanced Computing Center (TACC), and the Comet supercomputer at the San Diego Supercomputer Center (SDSC).
Check out the crazy numbers from the TACC's Wrangler: a combination of 120 servers, each with Haswell-based Xeon CPU's, and a total of 10 petabytes (10,000TB!) of high performance flash data storage. The NSF says the supercomputer will have 3,000 processing cores dedicated to data analysis, with flash storage layers for analytics. The Wrangler supercomputer's bandwidth is said to be 1TB/s, with 275 million IOPS! By comparison, the Comet supercomputer will have “only” 1,024 Xeon CPU cores, with a 7 petabyte high-speed flash storage array. (Come on, guys... That’s like, wayyy less bytes.)
Supercomputer under construction…probably (Image credit CBS/Paramount)
The supercomputers are part of the NSF's “Extreme Digital” (XD) research program, and their current priorities are "relevant to the problems faced in computing today”. Hmm, kind of makes you want to run a big muilti-SSD deathwish RAID, huh?

If you use the Firefox browser on a PC, you are probably using its "Desktop" application. They also had a version for "Modern" Windows 8.x that could be used from the Start Screen. You probably did not use it because fewer than 1000 people per day did. This is more than four orders of magnitude smaller than the number of users for Desktop's pre-release builds.
Yup, less than one-thousandth.
Jonathan Nightingale, VP of Firefox, stated that Mozilla would not be willing to release the product without committing to its future development and support. There was not enough interest to take on that burden and it was not forecast to have a big uptake in adoption, either.
From what we can see, it's pretty flat.
Paul Thurrott of WinSupersite does not blame Mozilla for killing "Metro" Firefox. He acknowledges that they gave it a shot and did not see enough pre-release interest to warrant a product. He places some of the blame on Microsoft for the limitations it places on browsers (especially on Windows RT). In my opinion, this is just a symptom of the larger problem of Windows post-7. Hopefully, Microsoft can correct these problems and do so in a way that benefits their users (and society as a whole).
