Enterprise AI Re-Skilling & Internals
GPU Architecture for Developers
GPUs reward parallel, predictable work and punish branching and random memory access. Developers who understand warps, memory hierarchy, and occupancy write faster code and waste less money. You do not need to be a CUDA expert, but you need the mental model.
要点
- Think in warps: threads execute together, so divergence serializes work.
- Coalesce memory accesses so a warp reads contiguous bytes in one transaction.
- Use shared memory for data reused within a block, and avoid bank conflicts.
- Size blocks and grids to maximize occupancy without exceeding register limits.
- Prefer batched, large kernels over many tiny ones to amortize launch overhead.
- Profile with Nsight or vendor tools before guessing at bottlenecks.
- Move data once and reuse it; PCIe transfers often dominate runtime.
- For ML, rely on optimized libraries and kernels rather than hand-written CUDA.
常见问题
Do I need to learn CUDA to use GPUs?
No for most ML work; yes if you are writing custom kernels or optimizing hot paths.
Why is my GPU utilization low?
Often small batch sizes, CPU bottlenecks, or data transfer stalls rather than compute limits.
Is more VRAM always better?
For model size and batch size yes, but bandwidth and compute matter for throughput.
How do I pick a GPU?
Match VRAM to your model and batch, and bandwidth to your kernel profile.
