Open Directory - Computers: Software: Operating Systems: Submicrokernel
See also: - Main idea: enforce no abstractions, rather, have them as options, to all levels of system: hardware, kernel and file services, ways users interact with system; based on exo principles. Descriptions, news. [Open Source] - Growing article, with links to many related topics. Wikipedia. - Traditional OSs limit application performance, flexibility, functionality by fixing interfaces and implementations of OS abstractions such as interprocess communication and virtual memory. Exokernel address this via application-level management of physical resources. [ResearchIndex] - Puts applications in control, runs 10x or more faster. Exopc and XOK versions run on x86 PCs. ExOS library gives user-level extensible implementation of Unix OS, so most applications compile and run with no change. Download. [Open Source, MIT] - Planned features: Exokernel architecture, object-oriented, POSIX compliant, intuitive GUI, and best technologies: journaled main filesystems, LibOS modular library. Development documentation. [Open Source, LGPL] - Downloads, announcements, and a forum. Programming languages: Assembly, C, and C++. - Growing article, with links to many related topics. Wikipedia. - Exokernel written in C/asm for the x86 architecture. Released under GPL. - Information, news, forum, CVS, downloads. [Open Source, GPL] - Makes µnOS: 72k microkernel on 8k nanokernel client/server architecture based on OOP framework, symmetric multithreading, multitasking, priority based scheduling, fully interruptible, separated address spaces, and full memory protection.
