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.
