Sprite File System There Are Three Important Aspects of the Sprite ®Le System: the Scale of the System, Location-Transparency, and Distributed State
Naming, State Management, and User-Level Extensions in the Sprite Distributed File System Copyright 1990 Brent Ballinger Welch CHAPTER 1 Introduction ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ This dissertation concerns network computing environments. Advances in network and microprocessor technology have caused a shift from stand-alone timesharing systems to networks of powerful personal computers. Operating systems designed for stand-alone timesharing hosts do not adapt easily to a distributed environment. Resources like disk storage, printers, and tape drives are not concentrated at a single point. Instead, they are scattered around the network under the control of different hosts. New operating system mechanisms are needed to handle this sort of distribution so that users and application programs need not worry about the distributed nature of the underlying system. This dissertation explores the approach of centering a distributed computing environment around a shared network ®le system. The ®le system is chosen as a starting point because it is a heavily used service in stand-alone systems, and the read/write para- digm of the ®le system is a familiar one that can be applied to many system resources. The ®le system described in this dissertation provides a distributed name space for sys- tem resources, and it provides remote access facilities so all resources are available throughout the network. Resources accessible via the ®le system include disk storage, other types of peripheral devices, and user-implemented service applications. The result- ing system is one where resources are named and accessed via the shared ®le system, and the underlying distribution of the system among a collection of hosts is not important to users. -

Some common challenges for many small UAV systems are addressed, including gust disturbance rejection at low speeds, control power, and systems integration. A rapid prototyping simulation framework which grew out of these efforts is described. A number of navigation, attitude determination and control algorithms are suggested for use in specific applications. Thesis Supervisor: John J. Deyst Title: Professor of Aeronautics and Astronautics Acknowledgments The work described in this thesis was a result of team effort. Here I would like to thank people who contributed to both projects described in the thesis, and otherwise provided support during my two years at MIT.

This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software.

Distributed Virtual Machines: a System Architecture for Network Computing
Distributed Virtual Machines: A System Architecture for Network Computing Emin Gün Sirer, Robert Grimm, Arthur J. Gregory, Nathan Anderson, Brian N. Bershad {egs,rgrimm,artjg,nra,bershad}@cs.washington.edu http://kimera.cs.washington.edu Dept. of Computer Science & Engineering University of Washington Seattle, WA 98195-2350 Abstract Modern virtual machines, such as Java and Inferno, are emerging as network computing platforms. While these virtual machines provide higher-level abstractions and more sophisticated services than their predecessors from twenty years ago, their architecture has essentially remained unchanged. State of the art virtual machines are still monolithic, that is, they are comprised of closely-coupled service components, which are thus replicated over all computers in an organization. This crude replication of services forms one of the weakest points in today’s networked systems, as it creates widely acknowledged and well-publicized problems of security, manageability and performance. We have designed and implemented a new system architecture for network computing based on distributed virtual machines. In our system, virtual machine services that perform rule checking and code transformation are factored out of clients and are located in enterprise- wide network servers. The services operate by intercepting application code and modifying it on the fly to provide additional service functionality. This architecture reduces client resource demands and the size of the trusted computing base, establishes physical isolation between virtual machine services and creates a single point of administration. We demonstrate that such a distributed virtual machine architecture can provide substantially better integrity and manageability than a monolithic architecture, scales well with increasing numbers of clients, and does not entail high overhead.
