Manage unified memory and thermals during long-running ML jobs on NVIDIA DGX Spark. Use when planning memory headroom for a training run on GB10, when a job OOMs on unified memory, or when monitoring temperature and power during multi-hour training.

---# Spark Memory & Thermal Ops
DGX Spark's GB10 chip has one 128GB unified
memory (UMA) pool shared by CPU and GPU, and a
sustained power ceiling well below its rated
figure. Both break discrete-GPU assumptions:
headroom isn't what `nvidia-smi` reports, and a
run that starts fast will slow down mid-job
with nothing misconfigured. This skill covers
planning memory headroom, working an actual
OOM, and watching thermals across a long job.
For launch-time failure modes (ABI mismatches,
flash-attn, playbook breakage), see
`spark-training-gotchas` — this skill assumes
the job starts.
## Common Issues Quick Reference
| Situation | Do this |
|---|---|
| Planning headroom before launch | Budget against `free -g`, not `nvidia-smi` — see UMA Memory Model |
| Job OOMs on unified memory | Work the OOM Ladder in order: flush, then batch/pack, then method downgrade |
| Throughput drops mid-run | Check the power/temp log before assuming a config bug — see Thermal Monitoring |
