Research

Software performance engineering; analytic performance modeling using “layered queues”; discrete event simulation of distributed computer systems. Reverse engineering of distributed software systems through trace analysis; model building, solution and analysis process; software engineering; operating systems; operating system schedulers.

Application

Performance models of distributed computing systems are benefi cial at all stages of a project. Models are used to set performance budgets for components, to fi nd feasible designs and locate bottlenecks, and to plan the resources for installed systems, leading to substantial cost savings for a performance-sensitive project.
