The guide covers the execution model (threads, warps, blocks, grids), hardware constraints (streaming multiprocessors, registers, memory hierarchy), and memory optimization (coalescing, shared memory bank conflicts). It explains how to identify bottlenecks using profiling tools like Nsight Systems and Nsight Compute, distinguishing between compute-bound and memory-bound kernels. Key optimization strategies include fixing memory access patterns, managing occupancy, reducing warp divergence, and using CUDA streams for overlapping compute with data transfers. The workflow emphasizes measurement-driven optimization over guesswork. ## Full article daily.dev links to this article rather than hosting it.
