Split GPU workloads across two pools:
- ci-compile (L4-1-24G): for cargo check/test/build — cheaper, same
CUDA CC 8.9 as L40S, sufficient 24GB VRAM for compilation
- ci-build (L40S-1-48G): for hyperopt + training — 48GB VRAM needed
for large model training batches
Runner defaults to ci-compile; training jobs override to ci-build
via KUBERNETES_NODE_SELECTOR. Both pools autoscale to zero when idle.
