Abstract 1 Given the dynamic nature of grid resources, adaptation is required to sustain a
predictable level of application performance. A prerequisite of adaptation is the recognition …

Writing large‐scale parallel and distributed scientific applications that make optimum use of
the multiprocessor is a challenging problem. Typically, computational resources are …

Wireless mesh networking (WMN), the static mesh routers (MRs) cooperatively relay each
other packets to the Internet Gateway (IGW). The routing protocols assume all the nodes in …

We present a methodology which allows to derive accurate and simple models which are
able to describe the performance of parallel applications without looking at the source code …

This dissertation presents a methodology to predict the performance of parallel computer
systems. In this de nition, a parallel computer system constitutes an imperative parallel …

This paper gives an overview of two related tools that we have developed to provide more
accurate measurement and modelling of the performance of message-passing …

Parallel computing is essential for solving very large scientific and engineering problems. An
effective parallel computing solution requires an appropriate parallel machine and a well …

Scalability analysis, which characterizes large-scale performance, is indispensable for
parallel-program performance debugging. To assist developers in this usually difficult …

In this paper we describe how a performance tuning tool-set, AIMS, guides the user towards
developing efficient and scalable production-level parallel programs by locating …

This paper discusses a new principle of interconnection network for massively parallel
architectures in the field of numerical computation. The principle is motivated by an analysis …
