As we prepare for the NAB show (National Association of Broadcasters) this week, AMD and Adobe have released a fairly substantial news release concerning the future of Premiere Pro, Adobe's flagship professional video editing suite.
Earlier today Adobe revealed some of its next generation professional video and audio products, including the next version of Adobe® Premiere Pro. Basically Adobe is giving users a sneak peek at the new features coming to the next versions of its software. And we’ve decided to give you a sneak peek too, providing a look at how the next version of Premiere Pro performs when accelerated by AMD FirePro™ 3D workstation graphics and OpenCL™ versus Nvidia Quadro workstation graphics and CUDA.
This will be the first time that OpenCL is used as the primary rendering engine for Premiere and is something that AMD has been hoping to see for many years. Previous versions of the software integrated support for NVIDIA's CUDA GPGPU programming models and the revolution of the Mercury Playback Engine was truly industry changing for video production. However, because it was using CUDA, AMD users were left out of these performance improvements in favor of the proprietary NVIDIA software solution.
Adobe's next version of Premiere Pro (though we aren't told when that will be released) switches from CUDA to OpenCL and the performance of the AMD GCN architecture is being shown off by AMD today.
Using 4K TIFF 24-bit sequence content, Microsoft Windows® 7 64-bit, Intel Xeon E5530 @ 2.40 GHZ and 12GB system memory, AMD compared several FirePro graphics cards (using OpenCL) against NVIDIA Quadro options (using CUDA). Idealy we would like to see some OpenCL NVIDIA benchmarks as well, but I assume we'll have to wait to test that here at PC Perspective.
AMD also claims that by utilizing OpenCL rather than CUDA, the AMD FirePro GPUs are running at a lower utilization, opening up more graphics processing power for other applications and development work.
While this performance testing is conducted on a pre-release version of the next Adobe Premiere Pro, we’re really pleased with the results. As with all of the professional applications we support, we’ll continue to make driver optimizations for Adobe Premiere Pro that can only help to improve the overall user experience and application performance. So if you’re considering a GPU upgrade as part of your transition to the next version of Adobe Premiere Pro, definitely consider taking a look at AMD FirePro™ 3D workstation graphics cards.

The GPU is slowly becoming the parallel processing complement to your branching logic-adept CPU. Developers have been slow to adopt this new technology but that does not hinder the hardware manufacturers from putting on a kettle of tea for when guests arrive.
While the transition to GPGPU is slower than I am sure many would like, developers are rarely quick on the uptake of new technologies. The Xbox 360 was one of the first platforms where unified shaders became mandatory and early developers avoided them by offloading vertex code to the CPU. On that note: how much software still gets released without multicore support?
Phoronix, practically the arbiter of all Linux news, decided to put several GPU drivers and their manufacturers to the test. AMD was up first and their results showed a pretty sizeable jump in performance at around October of this year through most of their tests. The article on NVIDIA arrived two days later and saw performance trended basically nowhere since February with the 295.20 release.
A key piece of information is that both benchmarks were performed with last generation GPUs: the GTX 460 on the NVIDIA side, with the 6950 holding AMD’s flag. You might note that 295.20 was the last tested driver to be released prior to the launch of Kepler.
These results seem to suggest that upon the launch of Kepler, NVIDIA did practically zero optimizations to their older "Fermi" architecture at least as far as these Linux OpenCL benchmarks are concerned. On the AMD side, it seems as though they are more willing to go back and advance the performance of their prior generation as they release new driver versions.
There are very few instances where AMD beats out NVIDIA in terms of driver support -- it is often a selling point for the jolly green giant -- but this appears to be a definite win for AMD.

Intel really seems to have taken the general criticism about the lack of Linux support during the initial release of Sandy Bridge to heart and made sure not to repeat the mistake with Ivy Bridge. Phoronix have spent the last two months exhaustively testing the performance of the i7-3770K and today offer some general observations about the chip and Intel's support of open source. Much of it is good news, like the performance of the OpenGL driver as well as its support for OpenGL 4.0 but some is not so good such as the fact that AMD's OpenCL for the CPU works better than Intel's implementation with neither running on the GPU yet. Check out the other findings in the article.
"It has been 66 days since Intel formally introduced their Ivy Bridge processors as the 2012 successor to Sandy Bridge. My views on Intel Ivy Bridge (specifically the Core i7 3770K model) back on launch-day were very positive in terms of the Linux compatibility, CPU performance, and the HD 4000 graphics capabilities. Since then I've conducted dozens of additional tests looking at the Core i7 Ivy Bridge on Linux in different areas from comparative benchmarks to Microsoft Windows, trying to run BSD operating systems on the latest hardware, looking at the virtualization performance, compiler tuning, etc. Here is a recap of this additional Ivy Bridge testing that has happened over the past two months of near constant benchmarking."

Two different stories today focus on how both major CPU vendors have allowed their support for the new features present in their architectures to fall behind for Linux OSes. From The Inquirer we hear about the how poor OpenCL support from AMD is leaving APU accelerated computing for Linux to lag behind Windows development. This goes far beyond purely graphical tasks and the complaints we have heard from gamers as OpenCL is a computing language that can handle far more than just pushing pixels. The two most common OpenCL applications that people are familiar with are the GPU clients for BOINC and Folding@Home, which enable you to chug work units on your graphics card or the graphics cores on your CPU. AMD's Neal Robinson who is the current senior director of Consumer Developer Support has taken up the challenge of promoting Linux OpenCL support from within AMD, so keep your eyes peeled for news from his team.
Intel's Ivy Bridge is no better according to Phoronix, as testing shows very little improvement on the default Ubuntu Unity desktop with Compiz. That is what allows Ubuntu users to show the iconic Desktop Cube on the Gnome desktop environment and using it shows negative effects on the general performance of the system. Switching to KDE and OpenGL generally resulted in better performance as did Xfce. Phoronix does not hold out much hope for the improvement of Compiz on Ivy Bridge processors or Intel's open source drivers for the near future, either for graphics or GPU accelerated computation.
"For AMD flaky Linux support isn't just a matter of gamers complaining, but now with its APUs, standard applications are simply not making use of the compute power that AMD needs to compete with Intel."

New Trojan.Badminer Malware Steals Your Spare Processing Cycles To Make Criminals Money At Your Expense

A new piece of malware was recently uncovered by anti-virus provider Symantec that seeks to profit from your spare computing cycles. Dubbed Trojan.Badminer, this insidious piece of code is a trojan that (so far) is capable of affecting Windows operating systems from Windows 98 to Windows 7. Once this trojan has been downloaded and executed (usually through an online attack vector via an unpatched bug in flash or java), it proceeds to create a number of files and registry entries.
It's a trojan infected bitcoin, oh the audacity of malware authors!
After it has propagated throughout the system, it is then able to run one of two mining programs. It will first search for a compatible graphics card, and run Phoenix Miner. However, if a graphics card is not found, it will fall back to RPC miner and instead steal your CPU cycles. The miners then start hashing in search of bitcoin blocks, and if found, will then send the reward money to the attacker’s account.
It should be noted that bitcoin mining itself is not inherently bad, and many people run it legitimately. In fact, if you are interested in learning more about bitcoins, we ran an article on them recently. This trojan on the other hand is malicious because it is infecting the user’s computer with unwanted code that steals processing cycles from the GPU and CPU to make the attacker money. All these GPU and CPU cycles come at the cost of reduced system responsiveness and electricity, which can add up to a rather large bill, depending on where you live and what hardware the trojan is able to get its hands on.
Right now, Symantec is offering up general tips on keeping users’ computers free from the infection, including enabling a software firewall (or at least being behind a router with its own firewall that blocks unsolicited incoming connections), running the computer as the lowest level user possible with UAC turned on, and not clicking on unsolicited email attachments or links.
If you are also a bitcoin miner, you may want to further protect yourself by securing your bitcoin wallet in the event that you also accidentally become infected by a trojan that seeks to steal the wallet.dat file (the file that essentially holds all your bitcoin currency).
Stay vigilant folks, and keep an eye out on your system GPU and CPU utilization in addion to using safer computing habits to keep nastly malware like this off of your system. On a more opinionated note, is it just me or have malware authors really hit a new low with this one?

AMD released its new APUs (Accelerated Processing Unit) to the masses, and now they are revving the processors up with a new software development kit that increases performance and efficiency of OpenCL based applications. The new version 2.5 APP SDK is tailored to the APU architecture where the CPU and GPU are on the same die. Building on the OpenCL standard, APP SDK 2.5 promises to reduce the bandwidth limitation of the CPU to GPU connection, allowing for effective data transfer rates as high as 15GB per second in AMDs A Series APUs. Further performance enhancements include reduced kernel launch times and PCIe overhead.
AMD states that the new APP SDK will improve multi-gpu support for AMD APU graphics paired with a discrete card, and will “enable advanced capabilities” to improve the user experience including gesture based interfaces, image stabilization, and 3D applications.
The new development kit is currently being used by developers worldwide in the AMD OpenCl coding competition, where up to $50,000 in prizes will be given away to winning software submissions. You can get started with the SDK here.

If you are a developer of applications which requires more performance than a CPU alone can provide then you are probably having a gleeful week. Today Microsoft announced their competitor to OpenCL and we have a large write-up about that aspect of their keynote address. If you are currently an OpenCL developer you are not left out, however, as AMD has announced new tools designed to make your life easier too.
General Purpose GPU utilities: Because BINK won't satisfy this crowd.
(Logo trademark Apple Inc.)
AMD’s spectrum of enhanced tools includes:
- gDEBuger: An OpenCL and OpenGL debugger, profiler, and memory analyzer released as a plugin for Visual Studio.
- Parallel Path Analyzer (PPA): A tool designed to profile data transfers and kernel execution across your system.
- Global Memory for Accelerators (GMAC) API: Lets developers use multiple devices without needing to manage multiple data buffers in both the CPU and the GPU.
- Task Manager API: A framework to manage scheduling kernels across devices.
These tools and utilities should make the development of software easier and allow more developers to take the risk on the new technology. The GPU has already proven itself worthy of more and more important tasks and it is only a matter of time before it is finally ubiquitous enough that it is a default component as important as the CPU itself. As an ironic aside, that should spur the adoption of PC Gaming given how many people would have sufficient hardware.

There is big news from AMD this morning, in addition to the Trinity news we saw from Computex they have purchased the makers of gDEBugger and have opened a new R&D centre in Tel Aviv. gDEBugger is a debugger for OpenGL and OpenCL for Windows, Mac and Linux and hopefully spells a resurgence for AMD's ailing professional level FirePro graphics cards. The Cayman family's two professional cards, the AMD FirePro V7900 and V5900 have just come onto the market to compete against NVIDIA's far more famous Quadro lineup and lag behind in raw performance but not in performance per dollar. Perhaps a strong feature set, including custom debugging tools will help AMD become a more attractive choice for graphics professionals. Drop by NGOHQ for more information on the purchase and the R&D centre.
"AMD announced the opening of a new research and development (R&D) center in Israel, located in the Tel-Aviv area. A world class team of highly talented software engineers is working on the latest heterogeneous computing technologies for the next generation of parallel computing platforms. This announcement follows AMD’s recent acquisition of Graphic Remedy, a renowned Israeli startup company specializing in development tools for heterogeneous computing and 3D graphics.
"We are extremely excited to have this new team on board working on AMD’s latest technologies and future products.” said Ben Bar-Haim, corporate vice president, software development, AMD."
