GPU program search is hindered by massive search space, requires abstraction
spikedoanz · x · 2026-08-15
The post discusses the challenges of GPU program search, noting that searching over nontrivial programs is a known difficult problem. Existing solutions involve lowering programs to abstract representations amenable to search (e.g., integer programming) or exhaustive search over locally correct rewrites (like Equality Saturation). The core bottleneck is the immense search space.
