Extensibility, safety and performance in the SPIN operating system

by Brian N. Bershad, Stefan Savage, Przemys Pardyak, Emin Gun Sirer, Marc E. Fiuczynski, David Becker, Craig Chambers, Susan Eggers , 1995
"... This paper describes the motivation, architecture and performance of SPIN, an extensible operating system. SPIN provides an extension infrastructure, together with a core set of extensible services, that allow applications to safely change the operating system's interface and implementation. Ex ..."

THE HARMONIC AND QUASICONFORMAL EXTENSION OPERATORS

by D A R I U S Z P A R T Y K A , K E N -I C H I S A K , A N , Jó Z E F Z A J A C
"... Abstract. Different aspects of the boundary value problem for quasiconformal mappings and Teichmüller spaces are expressed in a unified form by the use of the trace and extension operators. Moreover, some new results on harmonic and quasiconformal extensions are included. 1991 Mathematics Subject C ..."

Issues in Extensible Operating Systems

by Margo I. Seltzer, Yasuhiro Endo, Christopher Small, Keith A. Smith , 1997
"... Operating systems research has traditionally consisted of adding functionality to the operating system or inventing and evaluating new methods for performing functions. Regardless of the research goal, the single constant has been that the size and complexity of operating systems increase over time. ..."

its flexibility, allowing it to adapt to changes in the application set it must support. This paper discusses the issues involved in designing such extensible systems and the array of choices facing the operating system designer. We present a framework for describing extensible operating systems

Building An Extensible Operating System

by Christopher Allen Small , 1998
"... When designing an extensible operating system, a developer must ensure that the operating system is protected from misbehaved extensions. Two kinds of protection are needed: first, extensions should not violate the operating system’s interface, and second, extensions should not be able to leave the ..."

Explicit Extension Operators on Hierarchical Grids

by G. Haase, S.V. Nepomnyaschikh - East-West J. Numer. Math , 1998
"... Extension operators extend functions defined on the boundary of a domain into its interior. This paper presents explicit extension operators by means of multilevel decompositions on hierarchical grids. It is shown that the norm-preserving property of these operators holds for the 2D as well for the ..."

The Case for Extensible Operating Systems

by Margo Seltzer, Christopher Small, Keith Smith - Harvard University Center for , 1995
"... Many of the performance improvements cited in recent operating systems research describe specific enhancements to normal operating system functionality that improve performance in a set of designated test cases. Global changes of this sort can improve performance for one application, at the cost of ..."

Extensible Operating Systems

by Umesh Maheshwari , 1994
"... To exploit the high performance afforded by the hardware, applications must be allowed to customize the operating system according to their needs. A pertinent question is: What interface should the operating system kernel provide to the user-level code? This interface should be efficient, extensible ..."

Issues in the Design of an Extensible Operating System

by Stefan Savage, Brian N. Bershad - In OSDI , 1994
"... Extensible operating systems are designed around the principle that a system can be dynamically customized to best serve application needs. However, realizing this goal in a safe and efficient manner poses a number of unique problems. In this paper, we examine the requirements for constructing robus ..."

Extensible Operating Systems

by Priyank Porwal, Pratyusa Manadhata, Savage Stefan Savage, Brian N. Bershad, Issues In, Engler Dawson R. Engler, Et Al, Exokernel An Operating , 2001
"... Operating systems provide an abstract view of the underlying hardware to applications by dening an interface between the two. Traditionally, monolithic kernels hide hardware specifications and other useful information behind abstractions like processes, virtual memory, files and interprocess communi ..."

services to trusted user-level servers (e.g. microkernels), moving management of resources to untrusted user-level libraries (e.g. exokernels), or downloading code into kernel (e.g SPIN). This paper studies the extensibility features and methodologies of some of the proposed models of operating systems.
