Jacket Demo – CPU vs GPU runtimes on MATLAB® code

John MelonakosBenchmarks, CUDA 1 Comment

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!

Action Recognition with Independent Subspace Analysis

ArrayFireCase Studies Leave a Comment

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 algorithms that are hand crafted or use learned features.

Filtered Back-Projection and Non-Uniform FFTs

ArrayFireCase Studies Leave a Comment

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 plant. Filtered back-projection is at the core of all of these techniques: using the inverse Radon transform to reconstruct regular images from Fourier samples. Below you can see the final reconstructed image. Since these samples are often not on a uniform Cartesian grid, the non-uniform version of the FFT comes into play (NUFFT), and all of this requires some serious number crunching: bring in the …

Music Beat Analysis

ArrayFireCase Studies Leave a Comment

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 simplest (and least accurate) to more complicated algorithms that are highly accurate. All algorithms, though, perform some form of signal processing and frequency analysis, applications highly suited to GPU Computing. The beat visualizer described here was developed by researchers at Rice University, and is simple and fast. An incoming signal is broken down into six frequency bands for analysis. After smoothing out these bands and …

Tree cats see your code!

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 tree_cat sees bad code * Subsref [4] * M_ID 0(5) which * M_LRB 5(1) * ExprList [1] * M_ID 6(1) e * M_RRB 7(1) tree_cat sees bad code * Subsref [4] * M_ID 0(5) which * M_LRB 5(1) * ExprList [1] * M_ID 6(1) e * M_RRB 7(1) Top Secret:  Part of Jacket’s GPU runtime involves monkeys obtaining bananas for optimal performance.

High Performance Compressive Sensing

ArrayFireBenchmarks, Case Studies Leave a Comment

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 “compressive sensing” algorithms in reconstruction. This work deals with reconstruction of signals using partial Fourier matrices (RecPF).  The major computational components of the algorithm involve shrinkage and FFTs.  Jacket is employed to accelerate this compute-heavy code, and the resultant version (gRecPF) was about 5x faster! To reduce the cost involved in generating the random matrices involved in the above method, a second method (RecPC) that …
