zer-prof 1.1.0

Host-side NVTX profiling annotations for zer, trace! and trace_cuda! macros with zero-cost no-op fallback
Documentation

zer-prof

Host-side NVTX profiling annotations for the zer entity-resolution library.

Provides trace!, trace_cuda!, and trace_vulkan! macros that wrap code blocks with RAII NVTX ranges visible in Nsight Systems (nsys). All macros are zero-cost no-ops when no feature flag is enabled.

Feature flags

Flag Effect
cuda Activates NVTX; trace_cuda! emits named ranges
vulkan Activates NVTX; trace_vulkan! emits named ranges
avx2 Activates NVTX for AVX2 SIMD profiling
cpu Activates NVTX for CPU-path profiling
nvtx Standalone NVTX activation, no compute backend
(none) All macros expand to bare blocks, zero overhead

Usage

zer_prof::init(); // call once in main()

let result = zer_prof::trace!("compare_batch", {
    comparator.compare_batch(&pairs, &schema)
});

Filter by CUDA regions in Nsight Compute:

ncu --nvtx --nvtx-include "regex:^CUDA:.*" ./your_binary
