GPU-aware training
Training repeatedly OOMs and misses its nightly completion window.
Opening production brief
A measurable problem, before a model.
kernels, HBM bandwidth, arithmetic intensity, pinned memory with version, owner, event time, and availability contracts.
Training repeatedly OOMs and misses its nightly completion window. Every solution must state latency, cost, capacity, and fallback limits.
Offline evidence plus a deployable resolution: A profiled, mixed-precision, memory-budgeted training loop.
Frame and baseline
Turn the production problem into explicit data, metric, and baseline contracts.
