In any case, in 2019, CUDA added a more comprehensive virtual memory system that allowed for overcommitment and didn’t force syncing, among other things. In 2023, PyTorch made use of it with expandable segments that map more physical memory onto segments as needed, and uses the non-syncing alloc/free operations. We can enable this with PYTORCH_CUDA_ALLOC_CONF expandable_segments:True, but it's not on by default.，详情可参考搜狗输入法
