We present a novel approach for hybrid performance modeling and prediction of large-scale parallel and distributed computing systems, which combines mathematical modeling and discrete-event simulation. We use mathematical modeling to
develop parameterized performance models for components of the system. Thereafter, we use discrete-event simulation to describe the structure of system and the interaction
among its components. As a result we obtain a high-level performance model, which combines the evaluation speed of mathematical models with the structure awareness and fidelity of the simulation model. We evaluate empirically our approach with a real-world material science program that comprises more than 15,000 lines of code.
