# solvers.NetworkRooflineModel { #mlsysim.solvers.NetworkRooflineModel }

```python
solvers.NetworkRooflineModel()
```

Analyzes the Distributed Performance Bounds (The Network Wall).

This model elevates the single-node Roofline analysis to the fleet scale.
It calculates the Communication Intensity (CI) of a workload and identifies
if the fleet is Compute-Bound (Wall 1) or Network-Bound (Wall 2).
