This article proposes to address, in a tutorial style, the benefits of using Open Computing Language (OpenCL) as a quick way to allow programmers to express and exploit parallelism in signal processing algorithms, such as those used in error-correcting code systems.

Background Aligning short DNA reads to a reference sequence alignment is a prerequisite for detecting their biological origin and analyzing them in a phylogenetic context. With the PaPaRa tool we introduced a dedicated dynamic programming algorithm for simultaneously aligning short reads to reference alignments and corresponding evolutionary reference trees. The algorithm aligns short reads to…

We concentrated on two performance factors, namely the launching order of concurrent kernels and the kernel granularity. Extensive experiments show that the launching order of concurrent kernels can hardly affect application performance.

I will describe work on 2D and 3D semi-immersive environments and present novel on-and-above-the-surface techniques based on bi-manual models to take advantage of the continuous interaction space for creating and editing 3D models in stereoscopic environments.
Today at 10:30 AM MST (GMT-7). At SC12, NVIDIA is featuring advances in applications and scientific discovery made with accelerated computing. We invite you to visit us to see how others in your field are advancing science, as well as checking out the latest NVIDIA GPU technologies in accelerated computing.
After four years in Hamburg, ISC will move to the historic city of Leipzig in 2013. Leipzig has hosted trade fairs since 1165 and has long been a center for culture, learning and research.
IPV is an interactive protein visualizer based on a ray-tracing engine. Targeting high quality images and ease of interaction, IPV uses the latest GPU computing acceleration techniques, combined with natural user interfaces such as Kinect and Wiimotes.
Simulations such as this will help astronomers better understand the new findings in galaxy evolution. It tracks the development of a single disk galaxy from shortly after the Big Bang to the present day.
In this paper, we look into the hardware heterogeneity and the corresponding performance variation within the same instance type of Amazon Elastic Compute Cloud (Amazon EC2).
Intel is extending open standards support to include OpenCL 1.2 for Intel Xeon Phi coprocessors. OpenCL broadens the parallel programming options from Intel and allows developers to maximize parallel application performance on Intel Xeon Phi coprocessors.
The OpenACC standards group is pleased to announce the draft of the new OpenACC Version 2.0 specification at the SC12 Conference.
