In 2010, GPUs first supported virtual memory, but despite decades of development around virtual memory, CUDA virtual memory had two major limitations. First, it didn’t support memory overcommitment. That is, when you allocate virtual memory with CUDA, it immediately backs that with physical pages. In contrast, typically you get a large virtual memory space and physical memory is only mapped to virtual addresses when first accessed. Second, to be safe, freeing and mallocing forced a GPU sync which slowed them down a ton. This made applications like pytorch essentially manage memory themselves instead of completely relying on CUDA.
就这样，一个原本工具式的网络社区，被当成了“AI觉醒”的神话加以传播。而当这种内容成为传播的主要声音的时候，对这些歪曲事实的猎奇内容的所谓“辟谣”，也就自然而然地陷入了另外一种猎奇的模式。例如“Moltbook上绝大多数所谓的‘智能体’根本不具备自主性。约17000人控制着平台上的智能体，平均每人控制88个”之类阴谋论式的所谓“辟谣”也就开始出现了。，更多细节参见传奇私服官网
