Exokernel is an operating system kernel developed by the MIT Parallel and Distributed Operating Systems group, [1] and also a class of similar operating systems.

An exokernel eliminates the notion that an operating system should provide abstractions on which applications are built. Instead, it concentrates solely on securely multiplexing the raw hardware: from …

Exokernel Derivates While Monolithic Kernel and Microkernel are rather well-defined terms, the advocates of exokernel-like technology have coined many different terms - nanokernel, picokernel, …

The exokernel architecture removes these limitations by allowing untrusted software to imple-ment traditional operating system abstractions entirely at application-level. We have implemented a …

Summary The paper covers the exokernel architecture, which aims to minimize the "mechanism" role as much as possible, opting to leave implementations to the client, e.g. to the user's choice of library …

Discussion questions The exokernel mantra is to protect but not manage. What OS services will have the most troubles splitting these two? Is the exokernel fast because it has the right architecture? Or …
