Abstract

The field of modeling and simulation was long seen as a viable alternative to develop new algorithms and technologies and to enable the development of large-scale distributed systems, where analytical validations are prohibited by the nature of the encountered problems. The use of discrete-event simulators in the design and development of large scale distributed systems is appealing due to their efficiency and scalability. In this chapter we focus on the challenge to enable scalable, high-level, online simulation of applications, middleware, resources and networks to support scientific and systematic study of Grid and P2P applications and environments. We describe alternatives to designing and implementing simulators to be used in the validation of distributed systems, particularly Grid and P2Ps.

Background

Distributed systems have become very useful especially for complex scientific applications, involving the processing of very large data volumes, in a very short amount of time, as well as the storage of these data. Taking into account the tremendous popularity of complex distributed systems, favored by the rapid development of computing systems, high speed networks, and the Internet, it is clear that it is imperative, in order to achieve adequate performances in the utilization of these systems, to pick optimal architectures and solutions for designing and deploying distributed systems.
