Grid Environment VO

• Multiple users from different institutions
• Multiple geographically
• distributed resources in different administrative
  domains

• Large scale
• Uncountable number of resources
• Dynamicity
• VO, users, resources

5
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

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
