How much do amd64 microarchitecture levels help in Go?
Hacker News (AI keywords)6 days agoBenchmarkDaniel Lemire tests Go’s GOAMD64 levels using Roaring Bitmaps on a modern Intel Xeon. v2 brings strong gains where popcnt matters, while v3 adds further speedups in dense bitmap and set-operation workloads through AVX2. v4, despite implying AVX-512 support, shows no meaningful improvement in these benchmarks, likely due to current Go compiler limitations.
Warren's Abstract Machine: A Tutorial Reconstruction
Hacker News (AI keywords)8 days agoTutorialThis repository preserves Hassan Ait-Kaci’s out-of-print tutorial on the Warren Abstract Machine, a key execution model for Prolog and logic programming systems. It is not a new AI model or product launch, but a useful historical and educational resource. The material is most relevant to developers and researchers interested in symbolic AI, compilers, unification, backtracking, and logic language runtimes.
