Theoretical Aspects of Dynamic Distributed Systems: Report on the Workshop, Elche, Spain, September 26, 2009 Roberto Baldoni Dip. di Informatica e Sistemistica ÂAntonio Ruberti  Univ. degli Studi di Roma ÂLa Sapienza Â, Roma, Italy Alexander A. Shvartsman Computer Science and Engineering Univ. of Connecticut, Storrs, USA This is a report on the Workshop on Theoretical Aspects of Dynamic Distributed Systems, TADDS, that was held in Elche on September 26, 2009. The workshop was co-located with the International Symposium on Distributed Computing, DISC 2009. The meeting had its focus on the dynamic aspects of distributed http://lpd.epfl.ch/sgilbert/workshop/ ACM SIGACT News December 2009, vol. 40, no. 4 systems, encompassing systems in existence today and looking into the future development and deployment of dynamic distributed systems on the basis of sound theoretical foundations. Design, development, and deployment of distributed systems are ubiquitous in modern computing. The nature of distributed systems is evolving in response to speci Âc application requirements, and the advent of new classes of applications and technologies, such as VANET, Airborne Networks, Smart Environments, P2P, Broad Area Supercomputing, and Cloud Computing are radically changing the way we think about them. In these applications the initial set of processes is not known in advance, and the number of processes may change substantially over time as the system evolves due to changing needs of the applications and due to planned and unexpected perturbations in the computing medium. It is imperative for applications to accommodate such dynamic changes while maintaining their correctness. In order to manage such systems one cannot rely on a centralized management schemes that can either become a bottleneck or simply be unfeasible due to the size of the system. Instead, the processes need to behave autonomously, employing some form of self-management....
