Two fundamental problems in distributed network architecture grid, are Search and optimal timing for detecting the source for proper distribution of requests Scheduling and optimal scheduling is to minimize time and costs. In this paper a new approach to both The process of dividing the dependent and independent processing and load balancing processing is provided. Breastfed of ants algorithm based approach presented and in this graph corresponds to the load balancing ants algorithm may be used for load balancing. The use of this algorithm, another algorithm is used to optimize the timing that The registration schedule for each node in the runtime on each node for this request will take less time. With use a comparison, Can provide estimates for the timing and the estimated timing for a more efficient detection and application processing time, needed to be added. Simulations done, Show that with the algorithms presented Level can significantly increase the efficiency of distribution networks with architectural grid.

an integration of heterogeneous resources based on semantic grid is presented after thorough studies have been conducted on heterogeneous database integration of digital university libraries. Using OGSA-DAI middleware as the logical intergradation's layer, it establishes an ontology mapping layer and a semantic grid layer to deal with intermediaries such as grid agents and translation. Being able to describe users' retrieval needs accurately, this integration framework solves the problem of semantic heterogeneity, making information sharing possible. Experiments show that this integration based on semantic grid could improve search hits efficiently. © 2011 IEEE.

In a thin client computing architecture, application processing is delegated to a remote server rather than running the application locally. User input is forwarded to the server, and the rendered images are relayed through a dedicated remote display protocol to the user's device. Thin-client computing offers the promise of easier-to-maintain computational services with reduced total cost of ownership. With the increasingly development of cloud technology, the server side of thin client architecture is able to be deployed in cloud, thus makes the full use of the features of the cloud, for example, virtualization, flexibility, security, and dynamic management. Meanwhile the client side can also use the mobile thin device. The traditional thin client architecture, which is platform-dependant, however, limits the most benefit of the software providers and end-users. So we propose multi-platform thin client architecture, which use VNC (Virtual Network computing) protocol and run in the cloud environment. In this architecture, both side of the service will benefit a lot. In the one hand, the end-user can use cheap, light mobile terminal which enjoy all kind of software service of different platform. In the other hand, the software provider or developer can get more benefit with more download mass and wider circulated. (C) 2011 Published by Elsevier Ltd.

Business rules (a.k.a. integrity constraints) are crucial for maintaining the consistency of business intelligence data. However, business rule enforcement may easily be derailed by concurrent transactions. The problem is further aggravated by the usual insistence on two requirements: the total integrity premise and the isolated integrity premise. In order to limit the accumulation of integrity violations, while avoiding the stringency of the two premises, we propose a metric-based inconsistency-tolerant approach to the maintenance of business rules. © 2011 IEEE.

The purpose of the cloud-Enabled Space Weather Platform (CESWP) project is to bring the power and flexibility of cloud computing to space weather physicists. The goal is to lower the barriers for the physicists to conduct their science. That is, to make it easier to collaborate with other scientists, develop space weather models, run simulations, produce visualizations and enable provenance. Success of the project is measured by the broad acceptance and use of the platform by the space weather science community. To deliver cloud computing and storage, infrastructure as a service, the project has built an internationally distributed cloud based on Eucalyptus [1]. To provide a graphical user interface for the physicists to interact with we selected the Groovy programming language and the Grails web framework. To construct the software we followed the Scrum agile software development methodology. This paper will report on the motivation and risks of such an undertaking. It will also report on the suitability of Eucalyptus as a cloud framework and the utility of the tools used to build an application on top of it. © 2011 ACM.

cloud services are generally deployed in dedicated machines within Data-center. A cloud using distributed services and voluntary resources to build up its data center, where storage and computational resources of participating individual machines are harnessed non-intrusively, providing security to resources, services and users are primary objectives. Authentication and authorization are keys to any security mechanism. In this paper, we have made an attempt to address the associated concerns through an authentication and authorization model for a cloud computing paradigm. The paper also describes an improvement over traditional Kerberos protocol to authenticate the users and to access the services and resources in cloud, such that offsets certain limitations of Kerberos. © 2011 IEEE.

grid computing has made it possible for users to execute computationally expensive applications on dynamically acquired distributed resources. Users are allowed to combine data and analysis components distributed over the globe to build new complex applications. This architectural concept is further enhanced by the introduction of on-demand dynamic service provisioning to create ad-hoc Virtual Organizations as done in DynaSOAr. In this working paper, we present the architecture of a distributed Hash-table (DHT) facilitated framework, which uses Peer-to-Peer (P2P) concepts to enable dynamic on-demand service discovery and deployment on networked entities. One of the key features in this proposed framework is the use of decentralized Chord Ring instead of a centralized UDDI-based registry to cope with dynamic resource changes, thereby creating the basis of a fully dynamic virtual marketplace for computational resources. © 2011 IEEE.

The content business has witnessed a turning point toward service engineering. Information was a precious resource in the past, however, that is not so true anymore. Content providers need to address the issue of how they position themselves in terms of their standpoint on servicization. Mobile social games are increasingly attracting attention from the viewpoint of revenue-generating engines. The massive revenue-generating capability of mobile social games has accelerated the advances in service engineering. The author focuses on a mobile social game called "Peony Garden" and discusses the implications of servicization in the mobile content.

Tridimensional block multiword LDPC decoding on GPUs

JOURNAL OF SUPERcomputing 2011年第3期58卷 314-322页

In this paper, we describe a parallel algorithm for LDPC (Low Density Parity Check codes) decoding on a GPU (Graphics Processing Unit) using CUDA (Compute Unified Device Architecture). The strategy of the kernel grid and block design is shown and the multiword decoding operation is described using tridimensional blocks. The performance (speedup) of the proposed parallel algorithm is slightly better than the performance found in the literature when this is relatively good, and shows a great improvement in those cases with previously reported moderate or bad performance.

As a distributed computing framework, MapReduce partially overcomes centralized system's limitations about computation and storage. However, for matrix computation, there is a paradox between distributed data storage and intensive-coupled computing. To solve this problem, new approaches for matrix transposition and multiplication with MapReduce were brought forward. By applying a new model based on parallel matrix computing methods, the bottleneck of computing for logistic regression algorithm was overcome successfully. Experimental results proved that the new computing model can achieve nearly linear speedup. © 2011 Springer-Verlag.
