# Multi-Node Slurm

Convert single-node `uv run python -m torch.distributed.run` commands into multi-node Slurm sbatch scripts with Enroot container support, and debug common multi-node failures.

## First Answer Checklist

When converting or debugging Bridge multi-node jobs, answer in this order:

1. Prefer the **srun-native** launch shape for Bridge scripts that reach
   `initialize.py`: `#SBATCH --ntasks-per-node=8` and a direct `srun ... uv run
   python <script> ...` launch. Do not wrap these jobs in
   `python -m torch.distributed.run`.
2. State that Bridge derives `RANK`, `WORLD_SIZE`, `LOCAL_RANK`,
   `MASTER_ADDR`, and `MASTER_PORT` from SLURM variables during
