DAMON: Implementing Self-Driven Data Access-Aware Efficient Linux System
Explore the implementation of a self-driven data access-aware efficient Linux system in this 47-minute conference talk by SeongJae Park from Amazon. Dive into DAMON, a Linux kernel subsystem for efficient data access monitoring integrated into the mainline since v5.15, and its evolution to provide general access-aware system operations (DAMOS). Learn about the recent introduction of user aims-oriented system operations self-driving and the development of DAMO, a user-space tool supporting all DAMON features. Witness live demonstrations of data access profiling and self-tuning access-aware system memory efficiency optimizations. Gain insights into the internal mechanisms, recent changes, and practical applications of DAMON and DAMO. Discover additional access-aware optimization designs and implementations currently used in production, as well as future development plans and their evaluation results.
