  1. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 Scientific coordinator Christine Morin, INRIA Presented by Ana Oprescu, Vrije Universiteit Amsterdam October 22, 2008 XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576

  2. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS European R&D Projecthttp://www.xtreemos.eu • 4-year R&D project started in June 2006 in FP6 • 30 M€ budget, 14.2 M€ EC grant • 19 academic & industrial partners from Europe & China

  3. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Objectives • Design & implementation of an open source Linux-based Grid Operating System with native VO support • Grid Operating System A comprehensive set of cooperating system services providing a stable interface for a large-scalewide-area dynamic distributed infrastructure • Abstraction • Sharing of heterogeneous resources in multiple administrative domains • Two fundamental properties: transparency & scalability • Bring the Grid to standard users • Scale with the number of entities and adapt to evolving system composition

  4. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Architecture Overview

  5. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 VO Management & Security • Scalability of management of dynamic VOs • VO-centric security architecture • Dynamic mapping between Grid VO users & Linux entities with no modification to Linux kernel • No centralized Grid wide data base, no grid map file needed • Flexible administration of VOs • Multiple VO models supported (on-going research)‏ • Hierarchical policy management (VO, resource, user)‏ • Accountability of data access and service execution (on-going) • Interoperability with third party security infrastructures • Kerberos, LDAP, Shibboleth… • Single-Sign-On

  6. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 Application Execution Management • Objectives • Start, monitor, control applications • Discover, select, allocate resources to applications • Features • No assumption on local node RMS • AEM can be used without any batch system • Job “self-scheduling” • No global job scheduler • Resource discovery based on overlay networks • Multi-criteria and range of values queries • Unix-like job control • Accurate and flexible monitoring of job execution • Checkpointing service for grid jobs

  7. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemFS Grid File System • A global Grid file system • POSIX interface • Consistent data sharing • Efficient data access • Location-independent • Multiple VO users • Data storage in different administrative domains • Autonomous data management with self-organized replication & distribution

  8. Scalable & Highly Available Services • Resource Selection Service • A new P2P overlay to select resources from properties • No delegation: each node represents itself in the overlay • Application Directory Service • Support for dynamic information and data lifespan • Publish/subscribe • DHT-based structure for scalability • Unique feature: transactional guarantees • Virtual nodes • Transparent replication of Java-based services • Dynamic choice of replication protocol • Distributed servers • Transparent client handoff even in case of node failure

  9. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 Running Applications in XtreemOS GCM ProActive ?

  10. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 SAGA API C++/Java Implementation Structure

  11. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Flavours Stand-alone PC Cluster Mobile device

  12. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Cluster Flavour • Linux based Single System Image cluster OS • Illusion of a powerful SMP machine running Linux • Leverage Kerrighed full SSI • Posix compliant interface validated by successfully running the standard Linux Test Suite

  13. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Mobile Device Flavour • Objectives • Integration of XtreemOS services in mobile Linux OS enabling grid operation in an efficient and transparent way • Targets • Grid aware use cases • Grid users on the move • Grid-transparent use cases • Services given through a Grid infrastructure without the end users knowing it (Mobile Linux integrators)‏ • Portability

  14. XtreemOS IP project is funded by the European Commission under contract IST-FP6-033576 XtreemOS Software • First public release of XtreemOS software (open source) • November (7th) 2008 • Mandriva & RedFlag Linux distributions • http://www.xtreemos.eu & sf.net • Demonstrations • SC ‘08, Austin, November 16-20, 2008 (XtreemOS booth #3019)‏ • ICT’08, Lyon, November 25-27, 2008
