Sep 1, 2025In September 2025, the team delivered a comprehensive batch-reduce enhancement wave for the herbie repository, emphasizing reliability, performance, and future compatibility. The release includes a typed batch-reduce feature set with new fields and a separated spec-batch, along with refinements to batch-reduce.rkt and related contracts. This work improves API safety, clarity, and maintainability, and lays the groundwork for faster, scalable reductions in downstream workflows. Performance-focused changes—such as preallocated dvectors, optimized reducer placement, and caching strategies—reduce memory pressure and CPU overhead, contributing to lower latency on repeated computations. Additional quality investments include code formatting, unit tests for Taylor-related functionality and caching paths, and targeted maintenance cleanups. Key outcomes include safer batch-reduce semantics, better alignment with the next-stage pipeline, and measurable improvements to runtime efficiency and code health across the batch-reduce and Taylor ecosystems.

Jul 1, 2025During July 2025, the Herbie project delivered substantial improvements across library generation, numeric backends, CI/build automation, and batch processing. Key outcomes include stabilizing the libm generator with a new generators module and performance-focused cleanup; enhancements to the MPFR generator and a backend migration to bigfloat, improving numeric reliability and performance. CI and build systems were optimized to accelerate feedback (distributing CI jobs on push/fix/main, separating C builds for Linux/Windows, and runtime-only make-libm), and platform defaults were clarified. Batch processing saw core refactors and robustness improvements (batch-alive-nodes, batch-get-locations using vectors, and test environment upgrades), along with vector-related enhancements (gvector, in-dvector/dvector API fixes). Testing and platform debugging addressed racket environment issues and root-order ordering differences to stabilize nightly runs. Overall, these deliverables reduce build times, increase cross-platform reliability, and strengthen the foundation for scalable, correct numeric synthesis.

Feb 1, 2025February 2025 delivered a robust foundation for performance testing across two platform generations, expanded numeric coverage, and improved nightly results reliability for the Herbie project. We introduced two platform upgrades—Herbie 10 and Herbie 2.0 (herbie20)—with default nightly configurations and test integrations to enable consistent cross-platform comparisons and test isolation. Binary32 support was added to libm and associated platform definitions, broadening precision and benchmark fidelity. Nightly reporting robustness was strengthened by fixing zero-cost handling, adding type checks for speedup formatting, and aligning cost calculations to ensure repeatable results across platforms. Collectively, these efforts enhanced CI feedback speed, platform parity confidence, and applicability to broader workloads.
