Webpage has been discontinued Unfortunately, I no longer have time to maintain the webpages on operating system projects. In fact, I haven't updated the entries on the original page for well over 2 years, and it seems unlikely that I...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.

SPIN What if this were really really really important text up here? THE SPIN OPERATING SYSTEM SPIN is an operating system that blurs the distinction between kernels and applications. Applications traditionally live in user-level address spaces, separated from kernel resources and...Suggests solving networking and distributed systems latency via operating system extensibility; University of New Mexico Technical Report.

Using Kernel Extensions to Decrease the Latency of User-Level Communication Primitives University of New Mexico Technical Report Number CS96-4 System software overhead makes it impossible for a user application to achieve bandwidths and latencies near the hardware limits. This is especially true for remote handler invocation. Typically, the remote node has to trap into the kernel and perform an...Brief description, and on-site links to descriptions of Choices, Exokernel, GLUnix, VINO, SPIN.

Extensible Operating Systems An extensible operating system lets an application apply certain customization to tailor the operating system's behavior to the needs of the application. Applications running on personal computers have been taking advantage of the non-existing protection mechanisms in MS-DOS and the...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.
