Abstract

I'll present a novel method of modelling program execution on compute clusters. As previously, we use Performance Evaluation Process Algebra (PEPA) as the high-level modelling language, capturing both workload and computing fabric. The novel feature is that we make a continuous approximation of the state space underlying the PEPA model and represent it as a set of ordinary differential equations (ODEs) for solution, rather than a continuous time, but discrete state space, Markov chain.
