This comprehensive volume presents the proceedings of the Second International Conference and Exhibition on High-Performance Computing in Networking, HPCN Europe '95, held in Milan, Italy in May 1995 with the sponsorship of the CEC. The volume contains some 130 revised research papers together with a few invited papers and 16 poster presentations. All theoretical aspects of HPCN, regarding hardware as well as software, are addressed with a certain emphasis on parallel processing. The applications-oriented papers are devoted to a broad spectrum of problems from computational sciences and engineering, including physics, material sciences, climate and environmental applications, CAD, numerical algorithms in engineering, aerodynamic design, etc. In total the volume is a monumental documentation of HPCN efforts.
