Implementation Plan

• 1. Extend command line argument parsing for benchmark options

  • Add -b flag to enable benchmark mode in the argument parser
  • Add --size parameter for specifying random data size
  • Add --duration parameter for benchmark duration (floating-point seconds)
  • Update the Config struct to include optional BenchmarkConfig
  • Update usage/help text to include new benchmark options
  • Requirements: 1.1, 2.1, 2.2, 2.3, 2.4

• 2. Implement benchmark data structures and validation

  • Create BenchmarkConfig struct with size and duration fields
  • Create BenchmarkData enum to handle in-memory vs file data sources
  • Create BenchmarkRunner struct with algorithm, data, and duration
  • Create BenchmarkResult struct with all metrics including time per iteration
  • Add validation logic for benchmark parameters (positive values)
  • Requirements: 2.5, 3.4

• 3. Implement benchmark execution logic

  • Create benchmark runner with timing loop using std::time::Instant
  • Implement separate execution paths for in-memory data vs file data
  • Use std::hint::black_box() to prevent compiler optimizations
  • Calculate throughput in GiB/s and time per iteration with appropriate units
  • Integrate get_calculator_target() for acceleration target reporting
  • Requirements: 1.2, 1.3, 1.4, 1.5

• 4. Implement data source handling

  • Add random data generation function using rand::RngCore::fill_bytes()
  • Implement logic to determine data source (file, string, or generated)
  • Handle file size detection for throughput calculations
  • Create BenchmarkData instances based on user input
  • Requirements: 3.1, 3.2, 3.3

• 5. Integrate benchmark mode into main application flow

  • Modify main function to detect benchmark mode and route accordingly
  • Ensure mutual exclusivity validation between benchmark and normal modes
  • Add benchmark result formatting and display
  • Update error handling to include benchmark-specific errors
  • Maintain backward compatibility with existing functionality
  • Requirements: 3.4, 3.5

• 6. Add comprehensive testing for benchmark functionality

  • Write unit tests for argument parsing with benchmark flags
  • Test benchmark parameter validation (invalid sizes, durations)
  • Test data source selection logic (file vs string vs generated)
  • Test benchmark execution with different algorithms
  • Verify throughput calculation accuracy
  • Test error handling for invalid benchmark configurations
  • Requirements: All requirements
