Web-based service-oriented grid computing refers to a distributed computing system comprising a collection of interconnected and virtual computers that provides web-based services via the Internet. These services are based on Service Level Agreements (SLAs) established by negotiation between service providers and consumers. SLAs are contractual obligations that define the mutually agreed understandings...
A mortal finding out proteins logs into a pc and uses a complete network of computers to investigate knowledge. A man of affairs accesses his company's network through a personal organizer so as to forecast the long run of a selected stock. a military official accesses and coordinates pc resources on 3 completely different military networks to formulate a battle strategy. All of those situations have...
This paper describes a simple logical method to enhance the security in the grid computing. Object Based Grid Architecture (OGA) is a grid architecture based on object oriented concept to enhance the security in grid computing. In the grid environment the data and the process will be a public one since the job is executed on the public connected system and the resources will be shared among them with...
The Condor matchmaker provides a powerful mechanism for optimally matching between user task and resource provider requirements, making the Condor system a good choice for use as a meta-scheduler within the Grid. Integrating Condor within a wider Grid context is possible but only through modification to the Condor source code as each new mechanism for connection to remote resources is defined. In...
Hybrid service discovery is introduced as an efficient service discovery protocol in mobile ad-hoc grid witch has a good compromise between response time and network traffic overhead. In this paper we modify the basic idea of this protocol called Zone. We use multi-level zone in our proposal and called the protocol as multi-level hybrid service discovery protocol. Our algorithm tries to provide the...
The following topics are dealt with: mobility; quality of service; measure based and classification mechanism; clusters, grids, and distributed systems; processors and input/output systems; data security; multimedia communications; protocols; wireless networks; computer applications; real time systems; and voice over IP.
Ensembles of distributed, heterogeneous resources, or Computational Grids, have emerged as popular platforms for deploying large-scale and resource-intensive applications. Large collaborative efforts are currently underway to provide the necessary software infrastructure. Grid computing raises challenging issues in many areas of computer science, bioinformatics, high energy physics and especially...
With the spatial informationpsilas continuous expansion and increased popularity, the amount of the spatial information grow explosively, and the current services have not meet the needs of accessing to and processing spatial information. This thesis starts with the grid technology, doing researches to services oriented spatial information grid technology, focusing on the basic model and security...
Grid is essential for data-intensive application which involves great data transfer among different storage systems. One fundamental service that could be applied to any grid for reliable, high performance data transmission is discussed. Based upon standard FTP protocol, Grid FTP could be extended to the third-party control data transfer, striped data transfer and parallel data transfer. So a Grid...
XMPP (XML Messaging and Presence Protocol), also known as Jabber, is a popular instant messaging protocol that uses XML streams for communication. Due to it's high extensibility, XMPP is very easy to adapt to other uses than instant messaging. Furthermore, announcing of presence state makes it ideal for highly volatile environments. This paper outlines the use of XMPP for a grid-like computation environment...
A grid framework based teaching assistant system (EGP-System, Education Grid Platform) was proposed which adopted a bus based resource sharing and remote control technologies. Furthermore, a thin resource encapsulating interface modular was development which can be used to easily implement the inter-connectivity and inter-communication of campus computers and other electronic-resources. As a result...
A systematic scheme to form the watershed computational platform was developed based on lightweight Grid technique in this paper. The scheme that takes advantage of widely deployed local network makes full use of the non dedicated distributed computing resources. To overcome the vagary of overall system, MPICH-T a trust model based fault tolerant model was adopted, and the checkpoint based on pessimistic...
The aim of the present study is to build a collaborative ontology editing platform and environments. In this paper ontology takes the role of process description and integration drivers. It is obviously that the process ontologies need to involve as more as possible knowledge and expertise of multiple experts who are usually geographically dispersed. As a result, a network based, extendable and flexible...
In this paper, we present the design and architecture of an interoperable solution in order to transparently and securely access French and Japanese computing resources. The aim is to propose an international sparse linear algebra expert system available through a Web portal where a user can request some analysis on the resolution of a problem involving different kind of matrices, solvers and heuristics,...
After researching application of the business intelligence under network environment and grid technique which focus on information grid and OGSA-DAI, and for the need of integrating data and saving cost about enterprise, the technique of grid is combined with business intelligence network to carry out the enterprise cooperation and the knowledge share. A prototype of business intelligence network...
In domains of scientific and engineering computation, many applications share the characteristic that a large amount of batch jobs are included in the problem domain and these jobs can be executed concurrently on distributed resources. A register-based resource representing framework has been devised to allow these applications to be developed and executed independent of any specific resources, while...
This paper mainly uses the Globus to construct grid. Through analyzing the present resources, we propose a concept that computer can be reorganized into groups according to time. We use the self-defined information provider to put the dynamic data into the information service, and use supervisor to analyze and spot the breakdown of the system. This has advanced the speed of original grid searching...
This paper presents a Web portal system that supports visualization of a large number of data sets. On the Web site, users can browse or search for required data sets and select how the data should be visualized. Data sets can be retrieved from different locations via multiple protocols including SSH, HTTP, FTP and GridFTP. Visualization tasks can be executed on visualization servers at different...
