The XtreemOS operating system based on Mandriva Linux provides for Grids what a traditional operating system offers for a single computer: abstraction from the hardware and secure resource sharing between different users.
The XtreemOS operating system provides three major distributed services to users: application execution management (providing scalable resource discovery and job scheduling for distributed interactive applications), data management (accessing and storing data in XtreemFS, a POSIX-like file system spanning the Grid) and virtual organization management (building and operating dynamic virtual organizations).
Installed on each participating machine, the XtreemOS system will provide for the Grid what an operating system offers for a single computer: abstraction from the hardware, and secure resource sharing between different users. It would thus considerably ease the work of users belonging to VOs by giving them (as far as possible) the illusion of using a traditional computer, and releasing them from dealing with the complex resource management issues of a Grid environment.
By integrating Grid capabilities into the kernel, XtreemOS will also provide a more robust, secure and easier to manage infrastructure for system administrators.
