 In version 2.0, PyTorch on Windows with CPU directly utilizes the default malloc mechanism of Windows, which, compared to the malloc used in PyTorch Linux version 2.0, significantly increases the time for memory allocation, resulting in decreased performance. Intel engineer Xu Han took the initiative to replace the original Windows malloc mechanism, which PyTorch automatically calls, with another well-known malloc library developed by Microsoft, known as mimalloc. This replacement of malloc has already been released with Pytorch v2.1 and can significantly improve PyTorch's performance on Windows CPUs (See the following graph).
