AgentOS: Agent-based Distributed Operating System for Mobile Networks - Agent-based communication models show great promise to operate in unpredictable, metamorphic environments, such as mobile computing networks. Excellent basic explanations, clear arguments, well reasoned; from Crossroads, ACM student magazine.

GLUnix - Global Layer Unix; technology trends in high-speed, low-latency LANs suggest convergence of hardware in Massively Parallel Processors, MPPs, and Networks of Workstations, NOWs. Relative to many MPPs, NOWs offer more cost-effectiveness and scalability, and less hardware and software development time. Soon, the main difference between NOWs and MPPs will be OS software.
