zer-compute 1.1.0

Hardware-accelerated backend for zer, pairwise comparison and EM via CUDA, Vulkan, or AVX2
Documentation

zer-compute

Hardware-accelerated backend for the zer entity-resolution library.

Provides DeviceComparator and DeviceScorer as drop-in replacements for the CPU-only counterparts in zer-compare. Both implement the same zer_core traits, so the rest of the pipeline is fully backend-agnostic.

Feature flags

Flag Backend Requirements
cuda NVIDIA CUDA (SM 8.6+, Ampere / RTX 30-series) CUDA Toolkit 13.1+, nvcc at build time
vulkan Vulkan compute (NVIDIA Maxwell+, AMD, Intel) Vulkan 1.3 GPU, slangc on PATH at build time
avx2 x86_64 AVX2 SIMD No external toolchain
cpu Scalar CPU fallback Always available

When no flag is set the crate compiles normally using the scalar fallback from zer-compare.

Usage

use std::sync::Arc;
use zer_compute::{GpuBackend, DeviceComparator, DeviceScorer};

// Auto-detect: tries CUDA → AVX2 → CPU in order.
let backend    = Arc::new(GpuBackend::auto_detect());
let comparator = DeviceComparator::new(Arc::clone(&backend), &schema)?;
let scorer     = DeviceScorer::new(Arc::clone(&backend));
