This paper presents a parallel algorithm designed for Super-resolution Image Reconstruction based on Compressive sensing in the ATI Stream platform. In the accelerating process, we select part of the serial program as the objects to be sped up according to the execution time of each stage, set appropriate parallel granularity to make full use of […]

Time-domain circuit simulation is often dominated by the transistor model evaluation time. An analysis of a test suite of 27 circuits shows 66% of the transient runtime is spent evaluating the core BSIM4 transistor model code. A modern graphics processing unit (GPU) is a highly paralled, high performance computer suitable for non-graphics tasks. Circuit simulation […]

Network Intrusion Detection System has been widely used to protect computer systems from network attacks. Due to the ever-increasing number of attacks and network complexity, traditional software approaches on uni-processors have become inadequate for the current high-speed network. In this paper, we propose a novel parallel algorithm to speedup string matching performed on GPUs. We […]

This paper describes an implementation of a sonar image simulator optimized for running on a computer’s Graphics Processing Unit (GPU). GPUs are hardware-optimized to obtain maximum performance on computer graphics applications. Because these applications generally simulate focal plane images (i.e. optical systems, video, etc), some specific adaptations are required to render range images such as […]

Heterogeneous or co-processor architectures are becoming an important component of high productivity computing systems (HPCS). In this work the performance of a GPU based HPCS is compared with the performance of a commercially available FPGA based HPC. Contrary to previous approaches that focussed on specific examples, a broader analysis is performed by considering processes at […]

Adaptive mesh refinement (AMR) is a popular computational simulation technique used in various scientific and engineering fields. Although AMR data is organized in a hierarchical multi-resolution data structure, the traditional volume visualization algorithms such as ray-casting and splatting cannot handle the form without converting it to a sophisticated data structure. In this paper, we present […]

Modern smartphones use heterogeneous multi-core SoC which includes CPU, GPU, DSP and various application-specific accelerators. It provides opportunities to realize compute-intensive applications on a battery-powered and resource-limited mobile device by assigning each sub-task to the most suitable computing core. To meet the performance requirement with minimized energy consumption, the algorithm also needs to be characterized […]

In this paper, we have shown that exploitation of the GPU’s massively parallel architecture can dramatically increase the speed of MoM calculations. While the code can certainly be improved, matrix fill speed-up factors are already commonly found to be between 150X-260X. The conjugate gradient solver stands to be improved at this writing but still results […]
