Protean Compiler: An Agile Framework to Drive Fine-grain Phase Ordering

arXiv:2602.06142v3 Announce Type: replace-cross Abstract: The phase ordering problem has been a long-standing challenge since the late 1970s, yet it remains an open problem due to having a vast optimization space and an unbounded nature, making it an open-ended problem without a finite solution, one can limit the scope by reducing the number and the length of optimizations. Traditionally, such locally optimized decisions are made by hand-coded algorithms tuned for a small number of benchmarks, often requiring significant effort to be retuned when the benchmark suite changes. In the past 20 yea

Why this matters
Why now

The increasing complexity of modern compilers, driven by diverse hardware architectures and demanding software applications, necessitates more agile and intelligent optimization techniques.

Why it’s important

Improving compiler efficiency directly translates to better AI model performance, more efficient resource utilization, and faster development cycles for complex software, impacting the entire compute stack.

What changes

The shift from hand-tuned, rigid compiler optimizations to AI-driven, agile frameworks will significantly enhance program performance and adaptability across various compute environments.
