PARALLEL PROCESSING LETTERS Parallel Processing Letters (PPL) aims to disseminate rapidly results in the field of parallel processing in the form of short letters. It will have a wide scope and cover topics such as the design and analysis of parallel and distributed algorithms, the theory of parallel computation, parallel programming languages, parallel programming environments, parallel architectures and VLSI circuits. Original results are published, and experimental results if they contain an analysis corresponding to an abstract m odel of computation. PPL is be and ideal information vehicle for recent high quality achievements.
