The solver.py refactoring renamed most solver classes from *Solver to *Model (e.g. DistributedSolver → DistributedModel). The docs still referenced the old names, causing the Quarto site build to fail with: ImportError: cannot import name 'DistributedSolver' from 'mlsysim' - Fix executable code cells in tutorials/distributed.qmd - Update non-executable code examples across 10 doc files - Rename 19 API reference files from *Solver.qmd to *Model.qmd - SensitivitySolver and SynthesisSolver retain their names (correct) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

```python

core.solver.ReliabilityModel()

Calculates Mean Time Between Failures (MTBF) and optimal checkpointing intervals.
|
|
|
|
This solver handles the reliability modeling of massive clusters, helping
|
|
determine the 'Goodput' of long-running training jobs. It identifies
|
|
the probability of a job failure before completion and calculates the
|
|
Young-Daly optimal interval to minimize wasted compute time.
