"Easing Application Execution in Grids with XtreemOS Operating System"

This tutorial presents XtreemOS Grid system from the user point of view. Its goal is to show why XtreemOS is a system of choice for Grid users who want to easily execute their applications while taking advantage of advanced features for job management. We show what can be done with XtreemOS with regards to application execution, how it can be done and how the available features are implemented. Demonstrations will be presented throughout the tutorial.

Target audience: Grid users, Grid application developers, Grid system and middleware designers
