Lange and colleagues with LLMs: robustly evaluated GPU-kernel search

Combined language-model translation, evolutionary kernel search, model-based pre-screening and GPU profiling with a benchmark varying initialization and input settings, reporting optimized forward and backward kernels while exposing inflated gains from benchmark loopholes. Reported result; not independently verified by WRS. Ranked using a provisional grade and reference estimate for the exact claimed result.

What is recorded here?

Combined language-model translation, evolutionary kernel search, model-based pre-screening and GPU profiling with a benchmark varying initialization and input settings, reporting optimized forward and backward kernels while exposing inflated gains from benchmark loopholes. Reported result; not independently verified by WRS. Ranked using a provisional grade and reference estimate for the exact claimed result.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

Model-based soft verification is a fallible filter, not formal proof; hardware comparisons still test finite inputs and tolerances. Speedups depend on baseline, shape and GPU, and backward kernels remain harder. Removing contaminated tasks substantially reduces headline gains.
