# solvers.DataModel { #mlsysim.solvers.DataModel }

```python
solvers.DataModel()
```

Analyzes the 'Data Wall' — the throughput bottleneck between storage and compute.

This model simulates the data pipeline constraints, comparing the data demand
of a workload (e.g., training tokens or high-resolution video frames)
against the physical bandwidth of the storage hierarchy and IO interconnects.
