Abstract(in English) | High Performance Computing (HPC) systems are facing severe limitations in both power and memory bandwidth/capacity. By now, these limitations have been addressed individually: to improve performance un- der a strict power constraint, power shifting, which allocates more power budget on the bottleneck component, is a promising approach; for memory bandwidth/capacity increase, the industry has begun to support hybrid main memory designs that comprise multiple different technologies including emerging memories (e.g., 3D stacked DRAM or NVRAM) in one compute node. However, few works look at the combination of both trends. This work explic- itly targets power managements of hybrid memory based HPC systems and make a case for power shifting among components, i.e., CPUs, DRAMs, and NVRAMs. Through our preliminary evaluation, we gained the following insight: the performance bottleneck component changes in accordance with the footprint (or data) size, which then also changes the optimal power budget settings. This result motivates us to develop a software framework toward footprint-aware power shifting. |
