XtreemOS is a Grid operating system that provides native support for Virtual Organizations. Based on Linux, XtreemOS has 3 different versions capable of running on single PCs, clusters and mobile devices and provides for the Grid what an operating system offers for a single computer: abstraction from the hardware and secure resource sharing between different users.

The XtreemOS core functionalities allow securely managing computation and data resources: Virtual Organization and Security Management guarantees a secure operational environment for the Grid, covering all common requirements for information security as well as those intrinsic to the Grid; Application Execution Management allows starting, monitoring and controlling applications and selecting and allocating resources to them; and Data Management, a Grid file system (XtreemFS) allows targeting wide-area networks with high latencies. XtreemOS’ cluster version is based on the Kerrighed open source project, formerly developed by INRIA’s Paris project team, which provides a Single System Image operating system for clusters.

Additionally, XtreemOS is being comprehensively tested with a set of 11 reference applications from different sectors (aeronautics, economics, biology…) to ensure that end-user perspectives are taken into account in the design, implementation and validation of the system.
