Embodiment Construction

[0017] The present invention provides a method for virtual machines to share and use the graphics workstation GPU in a straight-through manner, and the method can enable multiple virtual machines to share and use the graphics workstation GPU in the straight-through method.

[0018] A schematic flowchart of a method for sharing and using a GPU of a graphics workstation in a direct manner provided by the present invention will be described in detail below in conjunction with the following drawings.

[0019] Such as figure 1 As shown, the method includes step S1: the cloud computing platform divides the graphics workstation GPU into several virtual GPUs, and assigns numbers and bus IDs to each divided virtual GPU. It is worth noting that in the process of splitting the graphics workstation GPU to form a virtual GPU, in order to ensure that each virtual machine under the cloud computing platform can allocate a virtual GPU, it should be ensured that the cloud computing platform div...

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...
