Virtual Organization Management in XtreemOS: an Overview
نویسندگان
چکیده
XtreemOS aims to build and promote a Linux based operating system to provide native Virtual Organization (VO) support in the next generation Grids. XtreemOS takes a different approach from many existing Grid middleware by: first, recognizing the fundamental role of VO in Grid computing and hence taking VO support into account from the very beginning of our design; and, second, getting around the overheads brought by layers of existing Grid middleware by enabling native VO support in the Linux operating system. This paper presents our vision of VOs in a Grid operating system and describes various aspects of VO management in our system architecture, ranging from lifecycle management, application execution management, security, to node-level enforcement mechanisms in operating system.

According to the description of work [19, Annex 1], the XtreemOS operating system is composed of two parts: 1) the foundation layer (XtreemOS-F), which is a modified Linux system, embedding Virtual Organization (VO) support mechanisms and providing an appropriate interface to implement 2) the high level operating system services, (XtreemOS-G). This document presents the specification of Linux-X...
متن کاملXtreemOS: a Sound Foundation for Cloud Infrastructure and Federations
XtreemOS is a Linux-based operating system with native support for virtual organizations (VO’s), for building large-scale resource federations. XtreemOS has been designed as a grid operating system, supporting the model of resource sharing among independent administrative domains. We argue, however, that the VO concept can be used to establish either resource sharing or resource isolation, or e...
متن کاملBuilding and Promoting a Linux-based Operating System to Support Virtual Organizations for Next Generation Grids Executive Summary
The XtreemOS operating system provides for Grids what a traditional operating system offers for a single computer: abstraction from the hardware and secure resource sharing between different users. It thus simplifies the work of users belonging to virtual organizations by giving them the illusion of using a traditional computer while removing the burden of complex resource management issues of ...
متن کاملSpecification of Federation Resource Management Mechanisms
The XtreemOS operating system is intended to be executed on all computers in a Grid, making their resources available for use as part of virtual organizations. There will be three XtreemOS flavours, one for each kind of Grid node: individual computers (typically for PCs), clusters, and mobile devices. As described in the ”Description of Work” document [13], the XtreemOS operating system is comp...
متن کاملXtreemOS-MD: Grid Computing from Mobile Devices
Grid and Cloud computing are well known topics, and currently one of the focus of many research and commercial projects. Nevertheless, the transparent access to Grid facilities from mobile devices (like PDAs or smartphones) is normally out of the scope of those initiatives, taking into account the intrinsic limitations of such devices: screen size and resolution, storage capacity, computational...
