Discrete GPUs are here to stay

September 12, 2011

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 [...]

Jacket Demo – CPU vs GPU runtimes on MATLAB® code

September 1, 2011

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 [...]

Action Recognition with Independent Subspace Analysis

August 19, 2011

Researchers at the Stanford Artificial Intelligence Laboratory (SAIL) have had more success (building on previous work) using Jacket to speed up their algorithm. In a paper at this year’s CVPR 2011, entitled “Learning hierarchical invariant spatio-temporal features for action recognition with independent subspace analysis”, they explain how their unsupervised feature learning algorithm competes with other [...]

Filtered Back-Projection and Non-Uniform FFTs

August 16, 2011

In order to investigate changes of forest biomass, scientists use microwave tomography to image the vegetation. At the smallest scale, individual plants can be imaged to investigate branching and growth, but even synthetic aperture radar can reveal large-scale changes in regional ecology. To the right, you can see the experimental setup to image an individual [...]

Music Beat Analysis with Jacket

August 11, 2011

Did you ever wonder how the music visualizer in your media player works? Watching it pulsate in synchrony with the beats of the song is almost as entertaining as listening to the song itself! Researchers have been attempting to detect beats in audio signals for many years, and there are many techniques available, from the [...]

Accelerating LTE Simulation Using Jacket

August 8, 2011

Simulation in MATLAB is a driving force in several research projects. However, the accompanying long simulation times can tend to be a drag in many of these  projects. In this article, we shall bring up the example of the work on 3GPP LTE System Simulation by Yuan Gao et al (from Tsinghua University, Beijing) and [...]

Tree cats see your code!

August 3, 2011

From time-to-time we stumble across funny quirks while using MATLAB®.  The latest came as one of our developers accidentally mis-keyed a few characters.  With 5 characters on the command line, you too can get a message about tree cats seeing your bad code (followed by a nasty seg fault, so beware).  Try this: >> a()@a [...]

High Performance Compressive Sensing

July 27, 2011

A few weeks ago, we published a blog entry that demonstrated the ability of Jacket to speed up “compressive sensing”, a technology that has wide applications in areas such as Image processing, reconstruction and spectroscopy. Here, we discuss the work of Nabor Reyna Jr. and Wotao Yin from Rice University using Jacket to speed up [...]
