A Deep Dive Into What Happens When a CUDA Kernel Runs
This article traces a simple CUDA vector-add program from source code through compilation and GPU execution, explaining how nvcc, PTX, and SASS fit into the pipeline. It also describes low-level runtime details such as warps, device memory access, and the mechanisms used to launch and complete the kernel on an RTX 4090.
