//! Comprehensive competitive benchmarking for RustyTorch++ Transformers
|
|
//!
|
|
//! This benchmark suite validates the 5-10x performance claims vs PyTorch 2.5, JAX, and TensorFlow.
|
|
//!
|
|
//! ## Benchmark Categories
|
|
//!
|
|
//! 1. **Training Speed**: Forward + backward pass throughput
|
|
//! 2. **Memory Efficiency**: Peak memory usage during training
|
|
//! 3. **Inference Latency**: Single token generation speed
|
|
//! 4. **Compilation Speed**: Model compilation and optimization time
|
|
//! 5. **Scalability**: Performance across different model sizes
|
|
//! 6. **Revolutionary Features**: Quantum/neuromorphic/edge capabilities
