Convert single-node scripts to multi-node Slurm sbatch jobs and debug common multi-node failures. Covers srun-native vs uv run torch.distributed approaches, container setup, NCCL timeouts, OOM sizing for MoE models, and interactive allocation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 `initialize.py` distributed init. 3. Require shared paths and matching container mounts for the repo, data, logs, `HF_HOME`, `UV_CACHE_DIR`, and `NEMO_HOME`. 4. For NCCL timeout reports, do these first-log checks before speculating: - grep for real errors while filtering warning/frame noise - inspect `Failures:` to find the first failed rank and node - grep for `ncclUniqueId`, `timeout`, or `crash on rank 0` ## Two Approaches: srun-native vs uv run torch.distributed …

How to install
mdr add nvidia/skills/nemo-mbridge-multi-node-slurm@sha256:1755991a2310d06dThe line at the top of this page pins the label git:20260602.e695a83, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
