+### Checkpoint and storage availability
+
+Cluster compute nodes may not share the same filesystem as login nodes or other clusters. Before running any workload that references a checkpoint path, verify the path is accessible from compute nodes:
+
+| Cluster type | Compute-node storage | NOT accessible from compute nodes |
+|-------------|---------------------|----------------------------------|
+| JET clusters (oci-hsg, cw, oci-nrt) | `/lustre/fsw/...` | Workstation NFS (`/home/scratch.*`), other cluster mounts |
+| dlcluster | `/home/omniml_data_*`, `/home/scratch.*` | `/lustre/` paths |
+
+If a checkpoint was produced on a different cluster or workstation, copy it to the target cluster's accessible storage before submitting jobs. NEL and SLURM do NOT sync checkpoints automatically.
+
 See `.claude/clusters.yaml.example` for a fully annotated example with multiple cluster types.

+### Container registry credentials (pyxis)
+
+If `srun --container-image` uses an image from a private registry (e.g., `nvcr.io/nvidia/...`), pyxis/enroot needs credentials on the cluster. Check for existing credentials and add if missing:
+
+```bash
+cat ~/.config/enroot/.credentials 2>/dev/null || echo "No credentials"
+# To add NGC credentials:
+mkdir -p ~/.config/enroot
+echo 'machine nvcr.io login $oauthtoken password <NGC_API_KEY>' > ~/.config/enroot/.credentials
+chmod 600 ~/.config/enroot/.credentials
+```

+Without this, `srun` will fail with `401 Unauthorized` when pulling from `nvcr.io`.

+### NEL CI and Cluster-Specific Notes
+
+For running evaluations on NVIDIA JET clusters (oci-hsg, cw, oci-nrt) or SLURM clusters like dlcluster, read `references/nel-ci-guide.md`. It covers:
+- NEL CI GitLab trigger pattern vs NEL SLURM executor
+- Cluster-specific GPU counts and storage paths
+- Checkpoint availability (compute nodes may not share login node filesystems)
+- Environment variable prefixes (`host:`, `lit:`) for SLURM executor
+- SGLang must bind `--host 0.0.0.0` for health checks
+- Directory setup and `chmod 777` for JET service account access
+- Common issues (NGC auth, gated datasets, walltime, `NEL_OTHER_OVERRIDES` space-splitting)
