GPU virtualization technology-based video memory resource allocation method, device and equipment

Abstract

A GPU virtualization technology-based video memory resource allocation method, device and equipment, the method comprising: obtaining video memory information of each virtual machine, the video memory information comprising a current remaining video memory space size of a main virtual machine and a video memory utilization rate of a guest virtual machine; determining whether a video memory allocation condition is met or not according to the video memory utilization rate; and if the video memory allocation condition is met and the size of the current residual video memory space of the main virtual machine is greater than a residual video memory space threshold, dividing the video memory space of the target value from the main virtual machine, and allocating the video memory space to the guest virtual machine meeting the video memory allocation condition. According to the method, for the use of the video memory space of the virtual machine, the video memory utilization rate of the guest virtual machine is dynamically obtained, and when the video memory utilization rate reaches a certain condition, the video memory is divided from the main virtual machine and allocated to the guest virtual machine, so that the sufficient video memory space of the virtual machine is ensured as much as possible, and the waste of idle video memory resources is reduced; the whole virtual domain environment is enabled to operate stably, and the overall system performance is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a GPU virtualization technology-based video memory resource allocation method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of processor technology and performance in recent years, virtualization technology has become more and more mature. At present, research on CPU virtualization, memory virtualization, network virtualization, and GPU virtualization has made significant progress. Each GPU has its own video memory space, so the development of GPU virtualization technology is also accompanied by the virtualization technology of video memory. [0003] With the application of GPU virtualization, the allocation of video memory virtualization will also appear. In the current mainstream virtualization technology, the video memory resource allocation method based on GPU virtualization technology is to statically al...
