CPU Microbenchmark

CPU-intensive workloads for performance evaluation using Sysbench.

What it does

CPU microbenchmarks test processor performance using:

  • Sysbench CPU: Prime number computation benchmark

How to run

Build the container

docker build -t sysbench_micro .

Individual container execution

# Run sysbench CPU test with prime number calculation
docker run -itd --name="worker" --runtime=runc --cpuset-cpus=0 --memory=512m sysbench_micro

# Execute the benchmark inside the container  
docker exec -itd worker /app/run_sysbench.sh 1 20000 1 300

# Copy results
docker exec worker cat /app/cpu.log > cpu_results.log

Parameters

  • threads: Number of CPU threads (e.g., 1)
  • primes: Maximum prime number for calculation (e.g., 20000)
  • duration: Test duration in seconds (e.g., 300)
  • runtime: Container runtime (runc, runsc-kvm)
  • container_mem: Memory limit per container (e.g., 512m)

Available scripts

  • run_sysbench.sh <threads> <primes> [output_file] <duration> - Run sysbench CPU tests
