Development Workflow
- Feature Development: Implement new benchmark capabilities
- Testing: Run comprehensive test suites to validate changes
- Documentation: Update README and testing guide
- CI/CD: Ensure all automated tests pass
- Performance Validation: Run regression tests to ensure no performance degradation
Best Practices
- Comprehensive Testing: Always include energy, memory, and regression testing
- Statistical Significance: Use proper statistical methods for performance comparisons
- Documentation: Keep documentation up-to-date with new features
- Reproducibility: Ensure benchmarks are reproducible across different environments
- Visualization: Include rich reporting and visualization for all new benchmarks
Current Limitations
Temporarily Disabled Features
The following features are currently disabled due to dependency issues and will be re-enabled in future releases:
- MLX Support: The
mlx
feature is commented out inCargo.toml
- Metal Support: The
metal
feature is temporarily disabled - Training Benchmarks: The
training
feature is disabled
Available Features
- Memory Profiling: Enable with
--features memory
- Standard Benchmarks: All core Candle operations are available
Troubleshooting
Common Issues
- Metal not available: Check macOS version and GPU support
- Compilation errors: Verify Rust version and dependencies
- Performance inconsistency: Ensure system is not under load during benchmarking
- MLX not available: Currently disabled - will be re-enabled in future releases
Debug Mode
Run with verbose output for debugging:
Memory Issues
For large tensor benchmarks, monitor system memory:
# Reduce tensor sizes for memory-constrained systems
Feature-Specific Issues
# Check available features
# Note: MLX and Metal features are currently disabled
# Use CPU-only benchmarks for now
