User Facility Support for Post-Exascale HPC Energy Efficiency
DescriptionEver since beginning the pursuit of achieving exascale HPC, the projected power and energy consumption was considered one of the major challenges. Due to the physical limits of silicon technology, exascale would require an infeasible amount of power and energy to invest and operate, and we had work to do. Fast forward to 2022, now that we have Frontier, the first exascale supercomputer on the floor, what’s next? Are we done? What does energy efficiency mean and how do we support it in this new post-exascale era? In this talk, I will first decompose energy efficiency and its realization at different lifecycles & layers of a supercomputer. Then discuss the status quo, highlighting the current challenges, gaps, and opportunities towards achieving HPC energy efficiency. In particular, motivated by the potential shift of focus that we will see in HPC, backed up with current efforts in OLCF, we will discuss the role of a user facility in this area and layout high-level action items, challenges and opportunities that starts by increasing our awareness of our energy consumption and its impact.
