Benign Workload Generator

The Benign Workload Generator is a suite of tools designed to simulate various workloads on servers and systems. These tools can be used for stress testing, performance benchmarking, or simulating real-world usage scenarios.

Structure and Key Scripts

1. Server Workload Scripts

• pure.sh:

  • Simulates a specific HTTP workload by performing repeated GET, POST, and PUT requests to a given server.
  • Server details (IP, port, and URI) and the number of requests can be customized.

• scenario_combine.sh:

  • Simulates a more dynamic HTTP workload with randomized request types (GET, POST, PUT) and adjustable concurrency limits.
  • Includes random pauses to simulate traffic patterns.

2. System Workload Scripts

• main-pure-task.sh:
  • Executes a series of predefined stress-test scripts, each targeting a specific system component or operation:
    • hdd: Tests hard disk I/O operations.
    • io: Simulates general input/output operations.
    • vm: Tests virtual memory usage.
    • matrix: Performs computational tasks like matrix calculations.
    • fork and vfork: Stress-tests process creation.
    • Additional scripts for file locking, caching, socket operations, and more.
  • Each script runs for a fixed duration (default: 120 seconds).

3. Supporting Workload Scripts

• The pure-task folder contains specialized scripts that are executed by main-pure-task.sh. Each script is focused on a specific workload category (e.g., aio.sh, malloc.sh, timer.sh, etc.).

Usage

Prerequisites

• Install curl for HTTP-based workloads.
• Install httperf for performance benchmarking (used in some scripts).
• Ensure you have sufficient system resources for stress testing.

Running the Scripts

1. Server Workloads:

   • Update server details in pure.sh and scenario_combine.sh (e.g., IP, port, URI).
   • Execute pure.sh or scenario_combine.sh to start workload generation.

   Example:

   bash pure.sh 0  # Perform GET requests

2. System Workloads:

   • Navigate to the directory containing main-pure-task.sh.

   • Run the script:

     bash main-pure-task.sh
