ArrayFire Support for CUDA 4.1
The question above comes from María (@turbonegra). She follows us @accelereyes. Many of you are wondering when ArrayFire support for new CUDA version 4.1 will be released. The answer: work is currently under way. CUDA 4.1 includes a new Fermi compiler, and many people in the GPU ecosystem have reported slowdowns from upgrading to the new CUDA version. So we’ve delayed releasing ArrayFire and Jacket support for CUDA 4.1 because we want to verify performance and reliability across all our unit tests, performance regressions, and customer code samples. Our tests sweep across various driver versions and everything from mobile GeForce cards through server-grade Tesla and Fermi chips. We are still working through the testing and verification at the moment. While …
Jacket over Remote Desktop for Tesla and Quadro GPUs
We recently reported that Jacket could be used over Windows Remote Desktop connections as long as you had an NVIDIA Tesla device in TCC mode. With the latest NVIDIA driver updates, Tesla and Quadro devices can be put into TCC mode, making it possible to use Jacket over Remote Desktop with both Tesla and Quadro devices. We have tested this out with the NVIDIA Quadro 4000 as well as Quadro 6000 GPUs. The system had a Tesla C2050 connected to the display, and the Quadro in TCC mode. Here’s the ginfo output: >> ginfo Jacket v2.0 (build 80c7ba4) by AccelerEyes (64-bit Windows) License Type: Designated Computer ([JACKET_ROOT]jacketenginejlicense.dat) Addons: MGL4, JMC, SDK, DLA, SLA CUDA toolkit 4.0, driver 285.62 GPU1 Quadro …

AccelerEyes Webinar Series
AccelerEyes invites you to participate in series of webinars designed to help you learn more about Jacket for MATLAB® and LibJacket for C/C++/Fortran/Python, a comprehensive library of GPU-accelerated functions. Joint Webinar With NVIDIA: LibJacket CUDA Library On October 20th we co-hosted a joint webinar with NVIDIA. During this well-attended event, our GPU computing experts provided a general product overview and usage of the LibJacket CUDA library. Several impressive demos of LibJacket in action were provided as well. LibJacket supports hundreds of GPU computing functions and programmers in numerous industries have been able to speedup applications. Be sure to check out the Q&A session included in the recorded webinar posted on NVIDIA’s Developer Zone. Thanks again to NVIDIA for co-hosting this informative webinar! GPU Programming for …
Filtering Benchmarks – OpenCV GPU vs LibJacket
OpenCV is one of the most popular computer vision toolkits, and over the last year they’ve been integrating more GPU processing into the core. One of the most common image processing tasks is convolution. Since LibJacket and OpenCV both support this, one of my coworkers rolled up his sleeves and benchmarked the latest versions from both libraries: OpenCV/CPU, OpenCV/GPU, LibJacket. Jump over to his personal website for the full benchmark results and source code. From the graphs, the GPU implementations from OpenCV and LibJacket both easily outperform the default CPU version in OpenCV, but notice that LibJacket pushes performance even further and dominates OpenCV’s GPU implementation, especially when using separable filters. We’ve worked really hard the last few years to …
Discrete GPUs are here to stay
Ever since AccelerEyes began over 4 years ago, naysayers have flippantly tossed out the idea that somehow computing on discrete GPUs will soon go away. Some thought AMD’s Fusion would become the demise of discrete GPU computing. Others thought that Intel’s integrated graphics would squeeze high-end GPUs out of the market. Neither is anywhere close to disrupting the utility of discrete GPUs (especially those currently available from NVIDIA) for solving computational challenges that face domain professionals. Today, Jon Peddie Research introduced a free whitepaper describing the market forces and the sales projections of GPUs. From the article: “The facts speak for themselves. Those who are concerned about graphics performance will buy discrete GPU systems. As good as they are, embedded …
Jacket Demo – CPU vs GPU runtimes on MATLAB® code
To explore the differences between CPU-only computing and GPU-accelerated computing, the new Jacket Demo is really convenient. The Jacket Demo automatically launches two MATLAB® sessions, one running on the CPU-only and the other running on the GPU with Jacket. This side-by-side demo shows the computational speed of each processor as well as a visual depiction of the algorithm’s progression. A variety of different demos are provided. The Jacket Demo is included in every Jacket installation (found in the examples directory and launchable from the Start Menu in Windows). Checkout this video of the Jacket Demo in action on an i7 CPU with a Tesla C2050 GPU. Enjoy!
