SOLAR: AI-Powered Speed-of-Light Performance Analysis

SOLAR is a framework that automatically derives validated speed-of-light performance bounds from PyTorch and JAX source code. Combining an LLM frontend with deterministic components, it provides unfused, fused, and cache-aware SOL bounds with multi-fidelity analysis. Evaluated on KernelBench, JAX/Flax models, and robotics workloads, it enables headroom analysis, optimization discovery, cross-platform exploration, and inverse-roofline hardware provisioning.
