January 2026 — Plonky3/Plonky3 performance and capabilities update. Delivered a new multi-point evaluation kernel and focused code quality improvements to enable scalable verification pipelines and memory-efficient computations. Key features delivered: - Added columnwise_dot_product_batched to compute Mᵀ · [v0, ..., vN−1] for multiple weight vectors with a single matrix load per row, boosting efficiency for tall-narrow matrices. - Refactored columnwise_dot_product to use safer, cleaner iterator patterns (replacing izip! with std::zip) and simplified conversions. Benchmarks and impact: - Overhead of batched<1> is minimal (0–5%): negligible in practice. - Batched<2> yields 5–8% speedups on narrow matrices (128–512 columns); wide matrices (4096 columns) show no gain due to saturated memory bandwidth. - Benchmarks provide actionable guidance for deployment: memory-bandwidth-bound regimes should favor batched evaluation for narrow shapes. Accomplishments and business value: - Enables uniform multi-point evaluation supporting upcoming lifted-FRI work, improving verifier design flexibility and paving the way for faster proof verification. - Improves memory efficiency and reduces CPU time for core linear-algebra kernels, lowering operational costs for large-scale proofs. - Demonstrated end-to-end diligence with performance benchmarks and clear tradeoffs, informing future optimization priorities. Technologies/skills demonstrated: - Rust: advanced iterator usage, refactoring, and safe memory access patterns. - Performance engineering: micro-benchmarking, memory bandwidth considerations, and architecture-aware optimization (Apple M2 Pro benchmarking context). - Collaboration: co-authored contributions and code quality improvements." ,
