OSPP: Multiple-System Performance Verification Tool

The multi-system performance verification tool is located in the tools directory of A-Tune. It loads system parameters from compared systems and performs performance testing.

---

Introduction

Directory Structure

• conf: Configuration folder.
  • config.json: Configures the test mode and the host's IP and User information.
  • modify.conf: Configures the ulimit and sysctl parameters.
  • sysctl_parameters.json: A dictionary used for querying key-value pairs.
• data: Stores data processing results and performance test results.
• log: Log file.
• src: Main program.
• tests: Test files.
• tools: Third-party performance test tool.

Supported Features

• Two test modes:
  • communication_test: Supports three hosts. The local host controls remote PCs (PC 1 and PC 2) to perform cross-testing.
  • host_test: Supports cross-testing between the local PC and remote PCs.
• Three methods for modifying parameters:
  • copy by all: Supports loading all parameters.
  • copy by block: Supports block-based import.
  • copy by line: Supports line-by-line modification.
• Parameter backup
• Performance testing
  • CPU, memory and drives can be tested using UnixBench.
  • The network can be tested using Netperf.
  • You can configure additional performance test commands in the extra_benchmark field of modify.conf.

Dependencies

• Python 3.x
• UnixBench: Run cd ./tools && git clone https://github.com/kdlucas/byte-unixbench.git to install it.
• nertpef: Use the package manager to install it.

Using the Tool

Configuration

• Edit /config/config.json.
• Configure the ulimit and sysctl parameters in modify.conf.

Running the Main Program in multisystem_performance
