During the past years, Grid Computing has emerged as an important research field concerning to large-scale resource sharing. Several research and academic institutions have widely adopted this technology as a mechanism able to integrate services across distributed, heterogeneous, and dynamic virtual organizations. However, this rapid expansion is exposing the need to provide effective means to ...

The grid computing paradigm emerged recently as a new field distinguished from traditional distributed computing because of its focus on large-scale resource sharing and innovative high-performance applications. The grid infrastructure ties together a number of Virtual Organizations, that reflect dynamic collections of individuals, institutions and computational resources. Flexible, secure and ...

This paper describes the architecture of the first implementation of the In-VIGO grid-computing system. The architecture is designed to support computational tools for engineering and science research In Virtual Information Grid Organizations (as opposed to in vivo or in vitro experimental research). A novel aspect of In-VIGO is the extensive use of virtualization technology, emerging standards...

Quality of Service delivered to Grids by packet-switched networks, is one of the most important factors affecting performance and efficiency of both Grid applications and middleware. The use Virtual Private Network services can improve the overall performance of Grids in many respects. In this paper, we show how the security, privacy and Quality of Service offered by scalable on-demand VPN serv...

This paper describes and summarizes the current state of the development for making the Virtual Control Laboratory (VCLab) a GRID application within the ELeGI project. It introduces shortly into GRID techniques and shows how this GRIDifying process is performed to offer virtual scientific experiments (VSE) on the GRID. The architecture and some technical details of the prototype implementation ...

Establishment of a computational grid by non-dedicated resources depends significantly on owners/users cooperation. Proposed human profiling model is targeted to increasing of resource availability. It includes parameters of human, platform, application and resource management procedure. Model parameters are collected by a web questionnaire and monitoring tools, respectively. Generated list of ...

Grid systems have evolved over time from traditional grid computing to service grids. Grid computing focuses on high perfomance computing, based on the concepts of cluster-building and resource sharing, by which grid systems are able to solve dataand comptutationally intensive tasks. Service grids include additionally virtualized, application field-specific services, providing for geographicall...

The advantages offered by existing Grid frameworks have resulted in a wide range of applications adopting the Grid approach. The first generation of production Grids have focused on the creation of large virtual organizations that share high end resources as part of a static resource pool. However as many collaborative interactions take places on a sporadic or ad hoc fashion outside of the virt...

This paper describes the Virtual Laboratory for e-Health system which is currently being developed in the EU IST ViroLab project. The Virtual Laboratory is an environment that enables clinical researchers to prepare and execute computing experiments using a distributed Grid infrastructure, while not requiring in-depth Grid computing technologies knowledge. By virtualizing the hardware, computin...
