Explore the Data Access Monitoring Operator (DAMO), a user-space tool and Python library for access-aware profiling and optimization of Linux systems, in this 48-minute conference talk by SeongJae Park from Amazon. Learn about the Linux kernel's Data Access MONitor (DAMON) subsystem, which enables accurate, lightweight, and scalable data access monitoring. Discover how DAMON can be used for monitoring access patterns and developing data access-aware optimizations. Understand the DAMon-based Operation Schemes (DAMOS) feature, which allows implementing optimizations through simple configurations. Gain insights into DAMO's human-friendly interface for controlling in-kernel features. Follow demonstrations of DAMON and DAMOS using DAMO, including advanced tuning and system optimization examples. Learn how to write custom DAMON user space tools in Python using DAMO's core module as a library.
