This volume presents the proceedings of the joint meeting CONPAR 92 - VAPP V, held in Lyon, France, September 1992. The international Conferences on Parallel Processing (CONPAR) and the meetings on Vector and Parallel Processors in computational science (VAPP) have been held jointly since CONPAR 90 - VAPP IV, held in Zurich. The aim of the meeting presented in this volume is to review hardware and architecture developmentstogether with languages and software tools for supporting parallel processing and to highlight advances in models, algorithms, andapplications software on vector and parallel architectures. The papers in the volume are organized into sections on networks, software tools, distributed algorithms, dedicated architectures, numerical applications, systolic algorithms, parallel linear algebra, architectures, shared virtual memory, load balancing, data parallelism, parallel algorithms, image processing, compiling and scheduling, simulation and performance analysis, parallel artificialintelligence, dataflow architectures, parallel programming, and poster presentations.
