Modern Systems Extensible Kernels And Containers Ppt Download Download ppt "modern systems: extensible kernels and containers" similar presentations northwestern university 2007 winter – eecs 443 advanced operating systems exokernel: an operating system architecture for application level resource management. Exokernel. ‣ make small, fast kernel implementation by implementing simple primitives. ‣ exokernel. ‣ secure, fast way to access hardware resources. ‣ tlb secure bindings. ‣ system abstractions can be implemented efficiently by application. ‣ libos exokernel. ‣ applications can have fast, specialized implementations.
Modern Systems Extensible Kernels And Containers Ppt Download Motivation monolithic kernels just aren't good enough? conventional virtual memory isn't what userspace programs need (appel li '91) application level control of caching gives 45% speedup (cao et al '94) application specific vm increases performance (krueger '93, harty cheriton '92) filesystems for databases (stonebraker '81) and more. How do we solve them: design. secure bindings. downloading code. visible resource revocation. the abort protocol. revocation: kernel asks process for resource. “relinquish page 5 please”. process tracks state and returns resource. abort: kernel demands resource.

Computing systems 8, 2015 why extensible operating systems? most needs of applications are similar. not all needs of applications are identical. os provides least common denominator services and policies resource intensive applications (e.g., databases) avoid the os.
