  • A Caching Model of Operating System Kernel Functionality - Stanford Cache Kernel, supervisor-mode component of V++ OS; caches system objects (threads, address spaces) to raise performance; microkernel alternative, performance equals normal monolithic OSs, yet gives application-level control of system resources, more modularity, scalability, smaller size, means of fault containment.
  • Extensible Operating Systems - Brief description, and on-site links to descriptions of Choices, Exokernel, GLUnix, VINO, SPIN.
  • SPIN - Dynamically extensible, Exokernel-based, provides many core services: scheduler, kernel threads, domains, event dispatcher, security mechanisms, primitive VM operations. Blurs distinction between kernels and applications, which traditionally live in user-level address spaces, separated from kernel resources and services by an expensive protection boundary. Lets applications specialize the kernel by dynamically linking new code into running systems.
