high performance computing on graphics processing units: hgpu.org

The state-of-the-art general-purpose graphic processing units (GPGPUs) can offer very high computational throughput for general-purpose, highly-parallel applications using hundreds of available on-chip cores. Meanwhile, as technology is scaled down below 65nm, each core’s maximum frequency varies significantly due to increasing within-die variations. This, in turn, diminishes the throughput improvement of GPGPUs through technology scaling because […]

In this paper, we present and discuss high performance implementation of a wide class of image processing applications on a low-power massively parallel SIMD architecture, the ClearSpeed CSX700. We present parallel implementation results for four classes of image processing applications: feature detection (Harris Corner Detector), stereo vision (a class of SSD like algorithms), model estimation […]

Recent progress in High-Level Synthesis (HLS) techniques has helped raise the abstraction level of FPGA programming. However implementation and performance evaluation of the HLS-generated RTL, involves lengthy logic synthesis and physical design flows. Moreover, mapping of different levels of coarse grained parallelism onto hardware spatial parallelism affects the final FPGA-based performance both in terms of […]

The problem of automatically generating hardware modules from a high level representation of an application has been at the research forefront in the last few years. In this paper, we use OpenCL, an industry supported standard for writing programs that execute on multicore platforms and accelerators such as GPUs. Our architectural synthesis tool, SOpenCL (Silicon-OpenCL), […]

Aerial surveillance missions require a geographical region known as the area of interest to be inspected. The route that the aerial reconnaissance vehicle will follow is known as the flight route. Flight route planning operation has to be done before the actual mission is executed. A flight route may consist of hundreds of predefined geographical […]

The approach used to calculate the two-electron integral by many electronic structure packages including generalized atomic and molecular electronic structure system-UK has been designed for CPU-based compute units. We redesigned the two-electron compute algorithm for acceleration on a graphical processing unit (GPU). We report the acceleration strategy and illustrate it on the (ss|ss) type integrals. […]

The exposure of high dynamic range scenes needs special attention to capture all details. A new method for a low dynamic monitoring preview of the local scene details is presented. We follow the idea of edge preserving nonlinear bilateral filtering instead of classic methods such as linear high pass filtering or histogram equalization. Real-time performance […]

Bio-inspired computer vision is an emerging field. It aims to reproduce the capabilities of biological vision systems, eventually to simulate the visual functions for various purposes. In this paper, we propose a bio-inspired computer visual system using Graphical Processing Unit (GPU), and its application on breast cancer prognosis. The system extracts visual features from an […]

The plant leaf modeling and rendering is one of the most challenging problem in virtual botany due to its complex morphological and optical characteristics. In this paper, we present a method of realistic leaf modeling and rendering. We extract the leaf outline and venation by using the algorithm of leaf image edge detection. The leaf […]

Parallel computing becomes more and more popular and the scale of software improves accordingly. A large application is made up of many small tasks. Some statistics indicate that some tasks of 80% software can support parallel execution. The difficulties are how to decompose one application into many tasks and exploit the parallelization among these tasks. […]

Imaging systems for computer vision play an important role in today’s world. Typical computer vision systems operate on large scale scenes, where objects are relatively far from the camera and the depth of field in which objects appear focussed is large. Close-range camera systems, on the other hand, typically have a narrow depth of field. […]
