  22. ConclusionObjectives for the next four years

  23. Objectives & Scientific Challenges Efficient and Safe, Distributed and Parallel, Middleware&Applications • Clear Focus: No Operating Systems, No VMs, No JVMs • We keep investigations with our 3 strongly Intertwined Axes: (1) Active Objects and Distributed Components: Scale, Speed, Safety • E.g.Sterile Requests allowing for aggressive optimizations (ASP proven) • Efficient large scale execution with Asynchrony, Groups, P2P (2) Calculus and Formalisms for Distributed Computing: Machine Proven ASP • Formally prove the confluence of ASP Imperative • Specific Confluence: Stateful and Stateless object for global richer properties (3) Specification/Verification for Distributed Systems: Verification that scales • Real program: Exceptions, Multicast/Gathercast, First Class Futures • Handling Infinite parts of the systems (e.g. Request Queue, Topology)

  24. Concrete Milestones 2010: • Safe and efficient execution of Active Objects+Components on 10 000 Cores • Previous objective was stated at 5 000, we did 4 200 in 2008 Grid Plugtests • Demanding: Model + Architecture + Fault-Tolerance + Code + Tools • Safe Dynamic Reconfiguration of 500 Distributed Components (DAG, then Cycles) • Using Determinacy properties of ASP • Dealing with/Using the Asynchrony of Active Object • Bridging Active Objects, Distributed Components and SOA: • From Safe Reconfiguration to Safe Adaptability • Enforcement of QoS to respect SLA (HP, Oracle, …) • Model Checkable composition: Real Industrial Use Case by Non-Specialist • We achieved 16 Components, 5 levels, 10 parameters (CoCoMe benchmarks) • Concrete objective: from Specification to Safe Code Generation (reconfig.)
