Holistic Approaches to HPC Power and Workflow Management

Artificial Intelligence for Data Center Operations (AI Ops)

“…In that work, application-level power usage of a production system was characterized for the Peregrine supercomputer and potential methods for predicting power usage were explored based on a priori and in situ characteristics about application job type. Other related work has shown the effects of different approaches to power management, such as power throttling strategies like core parking, which for certain applications are optimal in minimizing performance losses while maximizing power savings leading to further reductions in PUE/ERE (Purkayastha et al, 2018). Other strategies like frequency reduction have also shown benefits in reducing power consumption without affecting performance for a different class of applications.…”
