MAGUS: Memory-Throughput-Based Uncore Frequency Scaling on Heterogeneous Systems (poster)
Authors: Zheng, Z., Sultanov, S., Papka, M. E., Lan, Z.
Publication: The 12th Greater Chicago Area Systems Research Workshop (GCASR), Chicago, IL URL: https://gcasr.org/2025/posters Prior uncore frequency tuning studies have primarily focused on conventional HPC workloads running on CPU-only systems. As HPC advances toward heterogeneous computing, integrating diverse GPU workloads on heterogeneous CPU-GPU systems, it becomes imperative to revisit and enhance uncore scaling. Our investigation reveals that uncore frequency scales down only when CPU power approaches its TDP (Thermal Design Power) -- a rare scenario in GPU-dominant applications -- resulting in unnecessary power waste in modern computing systems.
