• Acts as drop-in decorator without any changes of the underlying model
• Seamlessly integrates with Pytorch modules while preserving full compatibility (attributes and methods)

② 𝑭𝒖𝒍𝒍-𝑺𝒕𝒂𝒄𝒌 𝑴𝒐𝒅𝒆𝒍 𝑨𝒏𝒂𝒍𝒚𝒕𝒊𝒄𝒔

Holistic performance analytics across 5 dimensions:

1. Parameter Analysis

   • Total/trainable parameter quantification

   • Gradient state tracking (requires_grad flags)

2. Computational Profiling

   • FLOPs/MACs precision calculation
   • Operation-wise calculation distribution analysis
   • Dynamic input/output detection (number, type, shape, ...)

3. Memory Diagnostics

   • Input/output tensor memory awareness
   • Hierarchical memory consumption analysis

4. Inference latency & 5. Throughput benchmarking

   • Auto warm-up phase execution (eliminates cold-start bias)
   • Device-specific high-precision timing
   • Inference latency & Throughput Benchmarking

③ 𝑹𝒊𝒄𝒉 𝒗𝒊𝒔𝒖𝒂𝒍𝒊𝒛𝒂𝒕𝒊𝒐𝒏

1. Programmable tabular report

   • Dynamic table structure adjustment
   • Style customization and real-time rendering
   • Real-time data analysis in programmable way

2. Rich-text hierarchical operation tree

   • Style customization and real-time rendering
   • Smart module folding based on structural equivalence detection for intuitive model structure insights

④ 𝑭𝒊𝒏𝒆-𝑮𝒓𝒂𝒊𝒏𝒆𝒅 𝑪𝒖𝒔𝒕𝒐𝒎𝒊𝒛𝒂𝒕𝒊𝒐𝒏

• Real-time hot-reload rendering: Dynamic adjustment of rendering configuration for operation trees, report tables and their nested components
• Progressive update: Namespace assignment + dictionary batch update

⑤ 𝑪𝒐𝒏𝒇𝒊𝒈-𝑫𝒓𝒊𝒗𝒆𝒏 𝑹𝒖𝒏𝒕𝒊𝒎𝒆 𝑴𝒂𝒏𝒂𝒈𝒆𝒎𝒆𝒏𝒕

• Centralized control: Singleton-managed global configuration for dynamic behavior adjustment
• Portable presets: Export/import YAML profiles for runtime behaviors, eliminating repetitive setup

⑥ 𝑷𝒐𝒓𝒕𝒂𝒃𝒊𝒍𝒊𝒕𝒚 𝒂𝒏𝒅 𝑷𝒓𝒂𝒄𝒕𝒊𝒄𝒂𝒍𝒊𝒕𝒚

• Decoupled pipeline: Separation of data collection and visualization
• Automatic device synchronization: Maintains production-ready status by keeping model and data co-located
• Dual-mode reporting with export flexibility:
  • Measurement units mode vs. raw data mode
  • Multi-format export (CSV/Excel) for analysis integration
