CUDA semantics — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/notes/cuda.html
PyTorch supports the construction of CUDA graphs using stream capture, which puts a CUDA stream in capture mode. CUDA work issued to a capturing stream doesn’t actually run on the GPU. Instead, the work is recorded in a graph. After capture, the graph can be launched to run the GPU work as many times as needed.
