ThreadStone – CPU Benchmark Suite

Mission: a transparent, cross‑platform measurement of raw CPU throughput and scalability.

Crate layout

Crate	Description
core	Benchmark kernel, stats, JSON output
workloads	Test implementations
cli	End‑user command‑line interface

Usage:

Export the JSON Schema

# print to stdout
threadstone-cli schema

# or write to file
threadstone-cli schema -o result.schema.json

Quickstart

cargo install --path cli
threadstone run -w dhrystone -t 4 -s 3 -o results.json
threadstone verify results.json

Benchmark Scripts

Parallel Dhrystone

The run_dhry_parallel.sh script runs Dhrystone benchmarks in parallel to fully utilize all CPU cores:

# Run with default 5 samples per core
./run_dhry_parallel.sh

# Run with custom samples per core
./run_dhry_parallel.sh 10

This script automatically detects available CPU cores and spawns one benchmark instance per core to achieve maximum CPU utilization. It measures and reports total execution time and CPU time used.

Memory Bandwidth

# Run STREAM benchmark using all cores
cargo run -p threadstone-cli -- run -w stream --threads 0 --samples 5
