concept:hbm-bandwidth
Hbm Bandwidth
Hbm Bandwidth in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
GPU-aware training
What the GPU actually executes
GPU performance comes from feeding a few substantial, well-shaped kernels—not merely from placing tensors on a CUDA device.
GPU-aware trainingKeep it fed: loaders and async copies
A fast training step needs an equally deliberate supply chain from storage to pinned memory to the device.
GPU-aware trainingMixed precision without NaNs
Mixed precision is trustworthy only when dtype choices, loss scaling, skipped steps, and quality parity are all observable.
Courses & assignments
Dependency-authoritative learning units.
