VO1

• Multiple users from different institutions

• Multiple geographicallydistributed resources in different administrative domains

• Large scale• Uncountable number of resources

• Dynamicity• VO, users, resources

State of the Art

Current OS are not Grid-aware & not VO-aware

A variety of Grid middleware & Toolkits for Grid Computing

• Resource management • Changing interfaces• Security pitfalls• Complexity for users, programmers & administrators

XtreemOS Objectives

Design & implement a reference open source Grid operating system based on Linux

– Native support for virtual organizations

Validate the XtreemOS Grid OS with a set of real use cases on a large Grid testbed

Promote XtreemOS software in the Linux community and create communities of users and developers

Grid@Asia Workshop - Seoul, December 11-13, 2006 7

XtreemOS Research Challenges

Identify fundamental functionalities to be embedded in Linux for secure application execution in Grids

Build a set of scalable self-healing OS services for secure resource management in very large dynamic grids

Provide a simple Grid API compliant with Posix while adding new functionality and supporting Grid-aware applications

Aggregate cluster resources into powerful grid nodes by integrating single system image mechanisms in Linux

Build an XtreemOS flavour for mobile devices enabling ubiquitous access to grid resources
