myui's scalability [5 articles]

Abstract

Many distributed systems must be scalable, meaning that they must be economically deployable in a wide range of sizes and configurations. This paper presents a scalability metric based on cost-effectiveness, where the effectiveness is a function of the system's throughput and its quality of service. It is part of a framework which also includes a sealing strategy for introducing changes as a function of a scale factor, and an automated virtual design optimization at each scale factor. This is an adaptation ...

Abstract

Scalability is a frequently-claimed attribute of multiprocessor systems. While the basic notion is intuitive, scalability has no generally-accepted definition. For this reason, current use of the term adds more to marketing potential than technical insight.In this paper, I first examine formal definitions of scalability, but I fail to lind a useful, rigorous definition of it . I then question whether scalability is useful and conclude by challenging the technical community to either (1) rigorously define scalability or (2) stop ...
