This book constitutes the refereed proceedings of the 7th European PVM/MPI Users' Group Meeting held in Balatonfured, Hungary in September 2000. The 35 revised papers and seven posters presented were carefully reviewed and selected for inclusion in the book. The book offers topical sections on evaluation and performance, algorithms, extensions and improvements, implementation, heterogenous distributed systems, tools, and applications in science and engineering. All current aspects of the parallel virtual machine approach and the message passing interface paradigm are addressed.
