Method for sharing graphic workstation GPU by virtual machines in direct connection way

Abstract

The invention relates to the field of the computer technology, particularly to a method for sharing a graphic workstation GPU by virtual machines in a direct connection way. By adoption of the method, the graphic workstation GPU can be shared by multiple virtual machines in the direct connection way. The method for sharing the graphic workstation GPU by virtual machines in a direct connection way comprises the steps of dividing the graphic workstation GPU to form a plurality of virtual GPUs; configuring to generate virtual machines, and assigning control nodes and calculation nodes for the generated virtual machines; after the virtual machines are started, enabling the calculation nodes to read the working states of the virtual GPUs, and sending the numbers of the virtual GPUs in an idle state and a bus ID to the control nodes; and enabling the control nodes to select and allocate the virtual GPUs to the corresponding virtual machines to establish mounting connection between the virtual machines and the virtual GPUs.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for a virtual machine to share and use a graphics workstation GPU in a direct way. Background technique [0002] With the development of computer hardware equipment and the continuous improvement of hardware equipment's support for virtualization, the application occasions of virtual machines are becoming more and more extensive. In the process of using a virtual machine, users also put forward higher requirements on the graphics processing function of the virtual machine. However, in order to ensure the smooth running of the virtual machine and reduce the resource response requirements of the virtual machine, existing technical personnel usually adopt technical means such as reducing the display resolution of the virtual machine, limiting the color depth, and reducing the video frame rate. These compromise measures are bound to It will cause the performance of virtua...

However, in order to ensure the smooth running of the virtual machine and reduce the resource response requirements of the virtual machine, existing technical personnel usually adopt technical means such as reducing the display resolution of the virtual machine, limiting the color depth, and reducing the video frame rate. These compromise measures are bound to Can cause virtual machine user performance to be lower than regular computers

The graphics workstation GPU (GPU is the abbreviation of Graphics Processing Unit in English, and its Chinese meaning is graphics processor) is a professional device for processing graphics and image data. It has very powerful graphics processing capabilities. If it can provide a virtual The method of using the graphics workstation GPU on the virtual machine can effectively solve the defect that the graphics processing capability of the existing virtual machine is not enough.
