XtreemOS coming to a grid near you, Jun 2008

I recently got an email about an interesting European initiative to develop a grid operating system. The package, called XtreemOS, is a 4-year research project aiming to develop a grid operating system to simplify the use, management and programming of grids.

XtreemOS core functionalities allow to securely manage 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) targeting wide-area networks with high latencies. XtreemOS’ cluster version is based on the Kerrighed open source project (, 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.

The experiments will initially be carried out on the French national grid experimental platform Grid’5000 ( We plan to extend the initial test bed to the grid in the Netherlands (DAS-3 – and to the Chinese grid (CNGrid –

The first public release of XtreemOS will be available in June 2008, while demo prototypes of individual components are already available. You can find out more at
