DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Power and energy consumption are critical design factors for any next generation large-scale HPC system. The costs for energy are shifting the budgets from investment to operating costs, and more and more often the size of systems will be determined by its power needs. =0A=0AAs a consequence, the US Department of Energy (DOE) has set the ambitious limit of 20MW for the power consumption of their first exascale system, and many other funding agencies around the world have expressed similar goals. Yet, with todays HPC architectures and systems, this is still impossible and far out of reach: the goal will only be achievable through a complex set of mechanisms and approaches at all levels of the hardware and software stack, which will additionally and directly impact the application developer. On future HPC systems, running a code efficiently (as opposed to purely with high performance) will be a major requirement for the user.=0A=0AIn this tutorial, we will discuss the challenges caused by power and energy constraints, review available approaches in hardware and software, highlight impacts on HPC center design and operations, and ultimately show how this change in paradigm from cycle awareness to power awareness will impact application development.
