The drastic increase in the commodity computer and network performance for the last generation has a resultant of faster hardware and more sophisticated software. But, the supercomputers of the current generation are still incapable of solving the current problems in the field of science, engineering, and business. This problems arises as a single machine cannot facilitate the availability of various...
The paper presents application of SIP protocol in the context of bag-of-tasks grid architecture. The SIP protocol has been used in realization of the execution management service. The main idea is use of stateful SIP proxy as request broker. The paper provides description of the concept, and the prototype system that has been built, as well as calculation of estimated performance level and it's relation...
In the era of Internet, one of the most ultimate goals is that users can seamlessly access to any computing application or service at anywhere anytime. Computing infrastructuralization is the path to gradually address the challenge. In this work, elop computing is proposed that encapsulates and integrates various computing elements as services, benefiting from existing advanced computing technology,...
Fault tolerance is an important issue in service oriented architectures like Grid and Cloud systems, where many and heterogeneous machines are used. In this paper we present a flexible failure handling framework which extends a service-oriented architecture for Distributed Data Mining previously proposed, addressing the requirements for handling fault tolerance in service-oriented Grids. In particular,...
Scientific workflows are common in biomedical research, particularly for molecular docking simulations such as those used in drug discovery. Such workflows typically involve data distribution between computationally demanding stages which are usually mapped onto large scale compute resources. Volunteer or Desktop Grid (DG) computing can provide such infrastructure but has limitations resulting from...
In a multi-organization environment like the GRID, each institute might want to apply some boundaries on how its resources are being utlized by other institutes. A disagreement between the multi-Virtual Organizations (VOs) might happen in the security aspect for the policy framework. Mobile Grid Services has given the ability to move jobs, data and application software from nodes to nodes during jobs...
Databases are normally designed to support a specific application domain, and the globalization process brings new issues to integrate data from more than one database. This paper proposes an architecture to integrating databases, by demonstrating a method for integrating semantically heterogeneous databases with a single tool and grid computing technology, which enables access to different databases...
This paper presents a model, implementation and performance evaluation of a class loader for Java Platform entirely based on web services (WSBCL). Designed to address the needs of desktop grid computing middle wares, WSBCL can be integrated and used by any Java solution for distributed systems. This class loader allows low computational power devices to act in the role of class repository without...
Distributed architecture is a fundamental way for science and engineering data application by aggregate power of computing resources connected by networks of the grid. This paper describes a innovative scenarios for intensive rainfall data analysis. The Flood Early Warning System is performed to give an alert in advance about the occurrence of heavy rainfalls around the world. The aim of the project...
Cloud computing is a computation or service based on concepts like virtualization, utility computing and grid computing provided to end users without requiring them to know the physical location of the system. Dynamic service management is achieved by implementing the cloud where dynamically scalable resources are provided as a service over the internet. In earlier works design of financial system...
Cloud Computing is catching more attention around the world with its excellent features in providing the services and advantages in economy both for the end-users and Cloud providers. However, due to lack of enough resources, Cloud vendors currently can only provide general resources and services, like computing as a service but not suitable for research on specific domain. Grid Computing, on the...
The lack of license management schemes in distributed environments is becoming a major obstacle for the commercial adoption of Grid or Cloud infrastructures. In this paper, we present a complete license management architecture that enables a pay-per-use license management which can be deployed together with an on-demand computing scenario. Our architecture enables authenticated access to a remote...
This paper presents a monitoring and forecasting system for Grid resources, based on Java and agent technologies. Performance monitoring, measurement and forecasting of Grid resources is an active research area, several researches and projects are studying and developing Grid information systems in order to provide users or schedulers with services necessary to determine which grid resource fulfills...
This paper designs the ScGridBroker as an scheduler of ScGrid that uses grid technology for managing large-scale distributed resources based on Economic Scheduling Algorithms. It discusses a layered and component-oriented modular architecture for the broker design and development. The architecture is generic enough to leverage services provided by various Grid middleware systems such as Globus, Legion,...
Through the grid services research and analysis, on the basis of the heterogeneous network and share resources, the design model of E-mail system which is based on the service grid anti-spam system is proposed and some functions are achieved. Through the GT containers the system with the pooling of anti-spam servers resources filter E-mail with distributed statistical method used in the entire network.
Technology is advancing rapidly and the demand and expectation is getting higher, that current monolithic client-server and peer-to-peer e-learning systems can no longer tolerate. Distributed e-learning systems, on the other hand, have the potential to address many shortcomings of current e-learning systems. Distributed systems are mainly based on Web-services or alternatively the Grid. The purpose...
The mobility issue in grid environments has established new challenges to the research communities particularly in the areas of scheduling, adaptation, security and mobility. Especially, the resource allocation becomes more challenging when mobility is considered in grid environment. Hence it is necessary to consider the mobility of users along with the resource availability while scheduling the resources...
With the increasing prevalence of large scale cloud computing environment, researchers has draw more attention about how to provide software as a service through the internet. In this paper, a novel approach named vSaaS is proposed in iVIC platform, which is the virtual computing environment for HaaS and SaaS applications. The aim of this approach is to provide the software as a service from a cloud...
Desktop Grids harvest the computing power of idle desktop computers whether these are volunteer or deployed at an institution. Allowing foreign applications to run on these resources requires the sender of the application to be trusted, but trust in goodwill is never enough. An efficient solution is to provide a secure isolated execution environment ("sandbox"), which does not constrain...
We present in this paper a secure and scalable Grid-based content management system for the management of high-volume multimedia data in the domain of the publishing industry. This is achieved by leveraging on existing individual solutions, such as the Alfresco content management system, the SRM standard for building scalable solutions based on the Grid and the GridTrust services for building trustworthy...
