●●●BangerWizardryBig Brain
NUMA-aware bash parallelizer hits 400× GNU Parallel speeds with verifiable builds.
Strengths
- •Born-local NUMA design eliminates cross-socket memory traffic on multi-socket systems
- •Embedded C extension with GitHub Actions verifiable builds prevents supply chain concerns
- •200k+ batch dispatches/sec with ordered output at zero performance penalty
Weaknesses
- •Performance gains only materialize on NUMA hardware, not typical developer laptops
- •Bash-based approach may limit adoption compared to Rust or Go alternatives
