A case for NOW (Networks of Workstations)

Networks of workstations are poised to become the primary computing infrastructure for science and engineering. NOWs may dramatically improve virtual memory and file system performance; achieve cheap, highly available, and scalable file storage: and provide multiple CPUs for parallel computing. Hurdles that remain include efficient communication hardware and software, global coordination of multiple workstation operating systems, and enterprise-scale network file systems. Our 100-node NOW prototype aims to demonstrate practical solutions to these challenges.< >
