Application performance and flexibility on exokernel systems – Dimensions

The exokernel operating system architecture safely gives untrusted software efficient control over hardware and software resources by separating management from protection. Communications of the ACM9 3March In addition to the body of readings around operating systems, the course will place a strong emphasis on your ability to critically read a paper, summarize your impressions of that paper in writing, and discuss what you have written with a group of your peers.

About project SlidePlayer Terms of Service. Communications of the ACM17 6June AU – Ganger, Gregory R. Application Performance and Flexibility on Exokernel Systems. This course surveys research literature relating to the design and implementation of operating systems. Frans Kaashoek, Dawson R. In classes where you are responsible for presentting a paper, you present a summary of the paper to the class and then lead discussion of the paper, using reviews and questions provided by the rest of the class as needed.

End-to-End Arguments in System Design. Frans ; Engler, Dawson R. It evaluates the exokernel architecture by measuring end-to-end application performance on Xok, an exokernel for Intel xbased computers, and by comparing Xok’s performance to the performance of two widely-used 4.

Hints for Computer System Design. In addition, the results show that customized applications can benefit substantially from control perfoemance their resources e. Dennis and Applicatlon C. The results show that common unmodified UNIX applications can enjoy the benefits of exokernels: Feedback Privacy Policy Feedback. Flexibiloty Kernel of a Multiprocessor Operating System.

This paper also describes insights about the exokernel approach gained through building three different exokernel systems, and presents novel approaches to resource multiplexing. Communications of the ACM11 5May By the time you finish the class, you should have a good understanding of the problems that have faced OS designers over about the past 50 years, how they solve them, and how these systems relate to OS and system design issues today.

Applications that do not want this responsibility communicate with the exokernel through libOSes. Xok exposes —The capabilities of the hardware like all MMU protection bits —Many kernel data structures like applictaion lists and inverse page mappings Paging is handled by applications.

The File System Most file system functions are left to untrusted library file systems libFSes —Will share access to the stable storage disk —Can define new file types with arbitrary metadata formats Problem is to give maximum of flexibility to these libFses while protecting files from aapplication accesses.
