I will present DAMON in FOSDEM'25. The title of the talk is “DAMON: Kernel Subsystem for Data Access Monitoring and Access-aware System Operations”.

I just made a DAMON logo using DAMON, like below. $ git clone https://github.com/sjp38/masim && cd masim $ cat damon_pixel_2 11111111 11 11 111111 11111111 11 11 11111111 11111111 1111 11111111 11111111 11 11 11111111 11111111 1111 11111111 $ ./pixels_to_access_config.py ./damon_pixel_2 $((100*1024*1024)) 300 damon.cfg $ sudo damo record "./masim ./configs/stairs.cfg" $ sudo damo report heatmap --output damon.png The output is below: The cropped one:

DAMON talk for OSSummit EU 2024 has accepted and scheduled. The talk will focus on use cases of DAMON for saving memory including those for real world products. The title of the talk is “DAMON Recipes: Ways to Save Memory Using a Linux Kernel Subsystem in the Real World”.

I will present and discuss about the current status and future plans of DAMON in Linux Storage/File System/Memory Management/BPF (LSFMM+BPF) 2024. The title of the talks is “DAMON updates and Plans: Automation of DAMON tuning, tiering, and VM guest scaling”. https://docs.google.com/spreadsheets/d/176LXLys9Uh6A-Eal2flrzcbUSJMUXGkGwyihr9jAAaQ/edit#gid=0

DAMON talk for OSSummit North America 2024 has been accepted and scheduled. The talk will present DAMOS auto-tuning and hopefully, more new DAMO features. The features are still under development, but hopefully, the power of presentation-driven development will make it. ;) Looking forward to meeting you there!

DAMON talk for OSSummit EU 2023 has accepted and scheduled. The talk will focus on its user-space tool, damo. It’s mainly for helping more audiences to digest the content easier, and also for accelerating the development of damo. By the time, hopefully the version of damo would reach to, or exceed 2.0.0, and newer interface and features will be introduced together. The title of the talk is “Data Access Monitoring Operator (DAMO): User-Space Tool/Python Library for Access-Aware Profiling and Optimization of Your Linux Systems”.

I will present DAMON, DAMOS, and DAMO in Open Source Summit North America 2023. The title of the talk is “DAMON, DAMOS, and DAMO: Kernel Subsystems and User-Space Tools for Data Access-Aware System Analysis/Optimizations”. https://sched.co/1K5HS

This document helps you estimating the amount of benefit that you could get from DAMON-based system optimizations, and describes how you could achieve it. Check The Signs No optimization can provide same extent of benefit to every case. Therefore you should first guess how much improvements you could get using DAMON. If some of below conditions match your situation, you could consider using DAMON. Low IPC and High Cache Miss Ratios.
