CompilerDream: Learning a Compiler World Model for General Code Optimization

arXiv:2404.16077v4 Announce Type: replace-cross Abstract: Effective code optimization in compilers is crucial for computer and software engineering. The success of these optimizations primarily depends on the selection and ordering of the optimization passes applied to the code. While most compilers rely on a fixed sequence of optimization passes, current methods to find the optimal sequence either employ impractically slow search algorithms or learning methods that struggle to generalize to code unseen during training. We introduce CompilerDream, a model-based reinforcement learning approach

Why this matters
Why now

The increasing complexity of software and the computational demands of AI models are driving the need for more efficient and generalizable code optimization methods, pushing research into AI-driven compilers.

Why it’s important

Optimizing compilers are critical infrastructure for computing performance, and AI-driven approaches have the potential to significantly enhance software efficiency across all domains, from cloud computing to edge devices.

What changes

This research introduces a machine learning approach that can learn to optimize code more effectively and generalize better than traditional methods, potentially leading to more performant software with less manual effort.
