AI Technical Summary
Technical Problem
Existing GPU virtualization technologies suffer from limited memory resources, low utilization, and a lack of hot and cold page identification and replacement mechanisms, leading to a decline in GPU performance.
Method used
By identifying cold and hot pages in the GPU page table, cold pages are swapped into system memory and hot pages are swapped into GPU memory. The system optimizes memory usage by periodically scanning threads and manages memory resources by setting margin thresholds and memory page pools.
Benefits of technology
This improves the utilization of video memory and reduces the need to use system memory as a substitute due to insufficient video memory, thereby enhancing the overall performance of the GPU and the stability of the system.

Abstract
The invention relates to a video memory management method and device, electronic equipment and a storage medium, the method is applied to a GPU drive in a virtual machine, and the method comprises the steps that when it is detected that the remaining amount of a GPU video memory is lower than a set remaining amount threshold value, cold pages in a GPU page table are recognized; wherein the cold page is a page table item which is not accessed in a recent preset time interval; and under the condition that the cold page is a video memory, replacing a physical address corresponding to the virtual address in the cold page to a physical address in a system memory so as to replace video memory data corresponding to the cold page to the system memory. The embodiment of the invention can improve the overall utilization rate of the video memory.
