Estimation of the Roofline Model with gem5

Type of study/Type of work: 

Bachelor or Master thesis


In this work, the roofline model shall be integrated in gem5. The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture. The work is divided in three parts. First the roofline for a configured gem5 architecture shall be generated automatically as a graphical output. Second, if an application is executed on gem5, it shall be drawn below the roofline. Finally, some analysis with specific benchmarks shall be conducted.

The Roofline model is an intuitive visual performance model used to provide performance estimates of a given compute kernel or application running on multi-core, many-core, or accelerator processor architectures, by showing inherent hardware limitations, and potential benefit and priority of optimizations. By combining locality, bandwidth, and different parallelization paradigms into a single performance figure, the model can be an effective alternative to assess the quality of attained performance instead of using simple percent-of-peak estimates, as it provides insights on both the implementation and inherent performance limitations.
