关于自主可控发展加速，以下几个关键信息值得重点关注。本文结合最新行业数据和专家观点，为您系统梳理核心要点。
首先，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.

最后，Still not right. Luckily, I guess. It would be bad news if activations or gradients took up that much space. The INT4 quantized weights are a bit non-standard. Here’s a hypothesis: maybe for each layer the weights are dequantized, the computation done, but the dequantized weights are never freed. Since the dequantization is also where the OOM occurs, the logic that initiates dequantization is right there in the stack trace.
