Preface The past twenty years have seen a flurry of activity in the arena of parallel and distributed computing. Most of the early results were developed for PRAM-like platforms, featuring various degrees of synchronization. While these models proved to be ideal testbeds for algorithm development, they ignored key implementation issues, including interprocessor communication, memory access, and synchronization. As a consequence, we are witnessing an increasing interest in more realistic computational models that better address practical concerns. In recent years, novel parallel and distributed computational models have been proposed in the literature, reflecting advances in new computational devices and environments such as optical interconnects, programmable gate arrays, networks of workstations, radio communications, mobile computing, DNA computing, quantum computing, etc. It is very encouraging to note that the advent of these new models has lead to significant advances in the resolution of various difficult problems of practical interest. The main goal of this workshop is to provide a timely forum for the exchange and dissemination of new ideas, techniques and research in the field of the new parallel and distributed computational models. The workshop is meant to bring together researchers and practitioners interested in all aspects of parallel and distributed computing taken in an inclusive, rather than exclusive, sense. We are convinced that the workshop atmosphere will be conducive to open and mutually beneficial exchanges of ideas between the participants. Topics of interest include, but are not limited to:
Models of Parallel and Distributed Computing Bulk Synchronous Parallel model, LogP model, Reconfigurable models, Optical models, Amorphous computing models, Radio communication models, Mobile computing models, Hardware-specific models, Biologically-based computing models. Algorithms and Applications Geometric and graph algorithms, Combinatorial algorithms, Randomized and approximation techniques, Numerical algorithms, Network algorithms, Distributed algorithms, Image processing, High-performance computing, Practical Aspects Architectural and implementation issues, Performance analysis and simulation, PVM/MPI, Design of network protocols, Development tools, Visualization, Sensor fusion, Fault tolerance.
