“…These results echo one of Lampson's hints: Don't Hade Power [8]. By relying on a language-level primitive that provided a high level programming abstraction, the object-based DDM gave up the ability to control its network management policies.…”

This paper provides an experimental comparison of two middleware data dissemination services: a distributed object-based service, and a message-based service. This paper compares these two services in the context of a common application: a wide-area network collaboratory, namely the Upper Atmospheric Research Collaboratory (UARC). UARCis an example of an application that reliably-streams data from a set of suppliers to a set of receivers. This comparison highlights the tradeoffs between ease of implementation and performance for a data streaming middleware service. By relying on a rigid language primitive, namely remote method invocation, the object-based dissemination service gave up the control over its transport policies. In contrast, the lower-level socket-based service was specifically constructed to provide a flexible interface to its applications. This flexibility allowed the middleware to better support data delivery t o a heterogeneous set of receivers. This is important in a wide-area distributed system where hosts are connected together over a broad spectrum of network links. This paper provides a concrete example of the effects of high-level design choices an the implementation of a wide-area distributed system's communication middleware.

“…To set the proper context, we began the class by covering five classic systems-building papers: "The Scientific Method" [14], "An Evaluation of the Ninth SOSP Submissions" [4], "The Task of the Referee" [11], "Hints for Computer System Design" [3], and "End-to-End Arguments in System Design" [9]. These papers are very important and do not require much context in order to understand many of the main points.…”

Web services as the foundation for learning complex software system development

A significant challenge for Computer Science departments is how best to get new graduate students involved with their chosen research projects. Ideally, the incoming graduate students will as a whole have both a solid understanding of computing principles behind large-scale software development and a broad "skill set", e.g., for conducting systems-oriented research. This rarely occurs, due to the diversity of backgrounds of incoming students-even the most qualified applicant can have deficiencies. To address this problem, we have developed a first-year graduate course that balances and integrates practical considerations with basic principles of complex software system development. To make the discussions of designing, implementing, and evaluating complex software systems more concrete, we situate the core of the class in the context of Web Services. We are currently teaching this class for the second time, and, while there will always be open issues given the nature and scope of this class, we have received positive feedback from the students and the other members of the department. Students recognize the practicality of Web Services. Students also appreciate the research possibilities that arise while evaluating the state of the art with regard to Web Services.

Hybrid Multi-level Cache Management Policy

Recently, multi-level cache became more popular due to its better performance than single level cache. It is very useful in distributed and parallel systems where number of applications is running at a time. The data required by application program is easily available in the cache due to larger size of the cache. Until now, many multi-level cache management policies LRU-K [15], PROMOTE [1], DEMOTE [5] has been developed but still there is performance issue. The main difficulty of these policies is selecting a victim. In this paper, a new policy is suggested which uses compressed caching and selects a victim depending upon three factors. First is how many times the promotion or the demotion of the cache block has done, second is size of the cache block to be replaced, and the third is recency of the block in the cache memory[1]. This policy is expected to exhibit better hit ratio than all the previously existing multi-level cache management policies.

Hints for computer system design

Abstract: Studying the design and implementation of a number of computer has led to some general hints for system design. They are described here and illustrated by many examples, ranging from hardware such as the Alto and the Dorado to application programs such as Bravo and Star.
