Reading up on simdjson

The maintainer of several widely-used C++ open-source libraries (ada, fastfloat, simdjson, simdutf) shares a summer of AI-optimization work on them.

The author spent the summer using AI techniques to optimize several widely used open-source libraries, including ada, fastfloat, simdjson, and simdutf.

The article shows that by exploiting symmetries of boolean scans, only three primitives (∧, <, ≠) need fast implementations to derive all others efficiently.
