Research

My research addresses the problem of allocating and managing workload onto interconnected resources in such a way that the workload's non-functional requirements are met. Typically, my research addresses application-specific computational workloads allocated over networked computing infrastructure, but I also work on the workload management in manufacturing and transport systems. I am particularly interested in two types of non-functional workload requirements that are increasingly difficult to optimise as system complexity increases: real-time performance and energy dissipation. I divide the resource allocation problem in three different areas, and I have made contributions to all of them together with my students and collaborators: workload modelling and profiling, estimation of real-time performance and energy dissipation in distributed platforms, and resource allocation algorithms and heuristics.
