DAMON: Data Access MONitoring and Access-aware System Operations

DAMON is a Linux kernel subsystem for efficient data access monitoring and access-aware system operations. It is designed for being

• accurate (for DRAM level memory management),

• light-weight (for production online usages),

• scalable (in terms of memory size),

• tunable (for flexible usages), and

• autoamted (for production operation without manual tunings).

• Frequently Asked Questions
  • Does DAMON support virtual memory only?
  • Can I simply monitor page granularity?
