Research ArticleOpen accessIn the abstractA Dynamic Resource Allocation Method for Parallel DataProcessing in Cloud ComputingV. Venkatesa Kumar, S. PalaniswamiProblem statement: One of the Cloud Services, Infrastructure as a Service (IaaS) provides a Compute resourses for demand in various applications like Parallel Data processing. The computer resources offered in the cloud are extremely dynamic and probably heterogeneous. Nephele is the first data processing framework to explicitly exploit the dynamic resource allocation offered by today’s IaaS clouds for both, task … …Journal of Computer Science, Vol. 8, Issue 5 · 1 Mar 2012 · 7,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteractive Computing Framework for Engineering ApplicationsJovana Knezevic, Jerome Frisch, Ralf-Peter Mundani, Ernst RankProblem statement: Even though the computational steering state-of-the-art environments allow users to embed their simulation codes as a module for an interactive steering without the necessity for their own expertise in high-performance computing and visualisation, e.g., these environments are limited in their possible applications and mostly entail heavy code changes in order to integrate the existing code. Approach: In this … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Computation Power by Reducing Query Response Time in Peer-to-Peer EnvironmentVelvizhi Nandagopal, D. ManjulaProblem statement: The Peer-to-Peer (P2P) was an emerging model and was being widely adopted in today’s internet computing.P2P traffic contributes the largest portion of the internet traffic which was unnecessary and led to delay. In existing Scalable Bipartite Overlay (SBO) network, Out of “N” peers, one group of peers were probing the messages (or) queries whereas the other group of … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Middleware for Grid ComputingS. Muruganantham, P. K. Srivastha, KhanaaProblem statement: "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment. Essentially, middleware is … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of Computational Grid Services in Enterprise Grid EnvironmentsR.J.A. Richard, Ajay Anant Joshi, C. EswaranGrid Computing refers to the development of high performance computing environment or virtual super computing environment by utilizing available computing resources in a LAN, WAN and Internet. This new emerging research field offers enormous opportunities for e-Science applications such as astrophysics, bioinformatics, aerospace modeling, cancer research etc. Grid involves coordinating and sharing of computing power, application, data storage, network resources … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,373 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamically Reconfigurable Embedded Architecture-An Alternative To Application-Specific Digital Signal Processing ArchitecturesN. Ramadass, S. Natarajan, J. Raja Paul PerinbamEmerging trends in design of real-time digital signal processing systems indicate that in the future, a significant amount of performance improvement can be achieved using dynamically reconfigurable embedded architectures consisting of reconfigurable, general-purpose components. Although embedded real-time systems have long been prevailing in our society, no firm scientific base has been established yet to handle timing requirements in a systematic … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Consumption and Performance’s Library on DSPs: Case Study MPEG2Jalel Ktari, Mohamed Abid, Nathalie Julien, Johann LaurentThe growing demand for portable electronic devices has led to an increased emphasis on power consumption within the semiconductor industry. As a result, designers are now encouraged to consider the impact of their decisions not only on speed and area, but also on power throughout the design space exploration. This article presents a high-level design space exploration methodology. It allows … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Complexity Performance Effective Task Scheduling Algorithm for Heterogeneous Computing EnvironmentsE. Ilavarasan, P. ThambiduraiA heterogeneous computing environment is a suite of heterogeneous processors interconnected by high-speed networks, thereby promising high speed processing of computationally intensive applications with diverse computing needs.

Research ArticleOpen accessIn the abstractExploring Strategies for Parallel Computing of RS Data Assimilation with SWAP-GAShamim Akhter, Kiyoshi Honda, Yann Chemin, Putchong UthayopasAn agro-hydrological simulation model is useful for agriculture monitoring. One issue in running such model is parameter identification, especially when the target area is large such as provincial or country level. Remote Sensing (RS) provides us with useful information over large area. RS cannot observe input parameters of agro-hydrological models directly. However, a method to estimate input parameters of such … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,214 accessesView PDFCite
