A Tiny Compiler for Data-Parallel Kernels

▤ Summary

This article explains a tiny compiler that lowers loop-based kernels into an explicit data-parallel form. It shows how the compiler distinguishes uniform values from varying values to decide whether operations can run across lanes. It also describes how masked loads, masked stores, and gathers map scalar code into vector-style execution. The piece focuses on compiler design concepts and implementation details rather than a company announcement or product release.
