5.1.8 Conclusion

In this work, we have identified the state of the art in terms of energy modeling and simulations for ultrascale systems. First, we describe a model for an ultrascale system, with special focus on Cloud data centers, then we move to modeling of individual PMs and switches. Once identified the main components to be modeled and the main challenges in their modeling, we describe how to perform simulations of energy consumption in ultrascale systems. Finally, we identify open challenges in energy modeling and simulation. In the future, we aim at proposing a holistic view of energy modeling, in order to capture the energy consumption of all components of ultrascale systems. In this way, we aim at having a fine-grained precise modeling of the whole system, in order to identify sources for energy leakages and pro-actively take actions to reduce them, thus increasing ultrascale systems’ energy efficiency. Concerning simulations, we aim at bringing such a holistic view of modeling in the design of ultrascale simulations. In this way, it will be possible to identify energy consumption in ultrascale systems and applications before they are running and improve them before the time they are deployed.
