About OPODIS

OPODIS is an open forum for the exchange of state-of-the-art knowledge concerning distributed computing and distributed computer systems. All aspects of distributed systems are within the scope of OPODIS, including theory, specification, design, performance, and system building. With strong roots in the theory of distributed systems, OPODIS now covers the whole range between the theoretical aspects and practical implementations of distributed systems, as well as experimentation and quantitative assessments.

Title: Accountable distributed computing
Abstract: There are two major ways to deal with failures in distributed computing: fault-tolerance and accountability. Fault-tolerance intends to anticipate failures by investing into replication and synchronization, so that the system’s correctness is not affected by faulty components. In contrast, accountability enables detecting failures a posteriori and raising undeniable evidences against faulty components. In this talk, we discuss how accountability can be achieved, both in generic and application-specific ways. We also discuss how fault detection can be combined with reconfiguration, opening an avenue towards "self-healing" systems that seamlessly replace faulty components with correct ones.

Title: Distributed algorithms: a challenging playground for model checking
Abstract: Distributed computing is increasingly spreading, in advanced technological applications as well as in our daily life. Failures in distributed algorithms can have important human and financial consequences, so that is is crucial to develop rigorous techniques to verify their correctness. Model checking is a model-based approach to formal verification, dating back the 80's. It has been successfully applied first to hardware, and later to software verification. Distributed computing raises new challenges for the model checking community, and calls for the development of new verification techniques and tools. In particular, the parameterized verification paradigm is nowadays blooming to help proving automatically the correctness of distributed algorithms.

Title: A fresh look at the design and implementation of communication paradigms
Abstract: Datacenter applications consist of many communicating components and evolve organically as requirements develop over time. In this talk I will present two projects that try to support such organic growth. The first project, Escher, recognizes that components of a distributed systems may themselves be distributed systems. Escher introduces a communication abstraction that hides the internals of a distributed component, and in particular how to communicate with it, from other components. Using Escher, a replicated server can invoke another replicated server without either server having to even know that the servers are replicated. The second project, Scalog, presents a datacenter scale totally ordered logging service. Logs are increasingly a central component in many datacenter applications, but log configurations can lead to significant hiccups in the performance of those applications. Scalog has seamless reconfiguration operations that allow it to scale up and down without any downtime.
