Distributed Systems and Computing

Lecturer:

Jan Janeček (gar.)

Tutor:

Jan Janeček (gar.), Peter Macejko

Supervisor:

Department of Computer Systems

Synopsis:

Students are introduced to methods for coordination of processes in distributed environment characterised by nondeterministic time responses of computing processes and communication channels. They learn basic algorithms that assure correctness of computations realized by a group of loosely coupled processes and mechanisms that support high availability of both data and services, and safety in case of failures.

Requirements:

Basic knowledge in the area of computer networks and communication.

Syllabus of lectures:

1. Distributed applications, synchronous and asynchronous model of computation.

2. Program support for distributed computation, middleware techniques.

3. Detection of the state of a distributed application, data consistency, logical time.

4. Distributed mechanisms for exclusive access.

5. Complexity of a distributed computation, client-server models, symmetry breaking.

6. Deadlocks, their prevention and detection, mechanisms for deadlock avoidance.

7. Termination of a distributed computation, termination detection algorithms.

8. Failures of a distributed computation, recovery, consensus, quorum techniques.

9. Data sharing and replication, security mechanisms in distributed databases.

10. Load balancing mechanisms for distributed computations.

11. P2P data systems, distributed hash tables (DHT).

12. Systems of DHTs: CAN, Pastry, Kademlia.

13. Mobility in distributed systems, mobile agents, active networks.

Study Objective:

The module focuses on the distributed computation viewed as an asynchronous cooperation of a group of finite state machines. Substantial part of the lectures is devoted to typical distributed computing techniques: ensuring causality, exclusive access, dealing with deadlocks, fault protection, mobility of computation, and security. The course is concluded with an overview of techniques for distributed data storages using the DHT (Distributed Hash Table) method and an overview of systems with mobile computing components.
