January 2, 2024 R Software Solution Tuning the Linux kernel with AI, according to ByteDance Why? Well, the idea, as Wang wryly put it, “is not to put Linux kernel engineers out of business.” No, the goal is “to liberate human engineers from tuning performance for each individual workload. While making better decisions with historical data, which humans often struggle with. And, last, but never least, find better solutions than those we come up with using our current trial and error, heuristic methods. Also: If you want to try BSD, go with GhostBSD How? The autotuning system is designed to automatically adjust the Linux kernel’s internal settings based on the specific workload and hardware configuration. This dynamic adjustment ensures optimal performance, addressing a long-standing challenge in the Linux community of manually tuning the kernel for specific scenarios. To do this, the AI/ML framework uses multiple algorithms such as Bayesian Optimization, Genetic Algorithm, and the Simulated Annealing/Evolutionary Algorithm The result? Dynamic Optimization: The system continuously monitors the kernel’s performance, making real-time adjustments to settings such as CPU frequency scaling and memory management. Enhanced Efficiency: By optimizing resource usage, the autotuning system significantly improves the efficiency of Linux systems, particularly in environments with varying workloads. User-Friendly Interface: The system includes a user-friendly interface, allowing even those with limited technical knowledge to benefit from enhanced kernel performance. Customizable Settings: Advanced users can customize the autotuning parameters, tailoring the system to their specific needs. It’s still early days, but ByteDance is already seeing some success. For example, by using DAMON, a Linux kernel subsystem for memory access monitoring and optimization, with the framework, they were able to find the best scheme for a MySQL application. It did this by running different DAMON schemes and comparing their performance. They found they could reduce the application’s memory usage by 30%. For massive applications, that’s a real savings. Also: Linux might be your best bet for heightening your desktop computer security In another case, ByteDance was able to optimize HTTP network latency on an NGINX server by optimizing the tuning of 16 kernel sysctl parameters. In its best scenario, the ML tuning gave the NGNIX network performance a 12% boost over expert manual tuning. Again, that’s a significant improvement. ByteDance isn’t claiming its AI/ML approach will work for every Linux tuning job, but Wang did say, “Although there are limitations, we believe that kernel machine learning is not only possible but also necessary.” Me? I think this is a potential game-changer for Linux applications. By simplifying the kernel optimization, it will make Linux more accessible and efficient for a broader range of users and applications. In particular, I see the autotuning system kicking up the performance on almost all servers, cloud computing, and data center applications.
