Managing Memory Bandwidth Antagonism at Scale

Explore memory bandwidth management and performance isolation in multi-tenant cloud environments through this Linux Plumbers Conference talk. Delve into Google's efforts to address isolation challenges caused by memory bandwidth saturation, including monitoring techniques, control mechanisms, and the use of Intel RDT. Learn about estimating container memory bandwidth utilization, implementing actuators and policies for control, and leveraging the resctrl interface. Gain insights into production use-cases, lessons learned, and proposed changes for resource control support in Linux. Understand the universal applicability of these challenges and join the discussion on developing common solutions for the community.
