GPU virtualization implementation method, vertex data caching method, and related devices

Abstract

Disclosed in the present invention are a GPU (Graphic Processing Unit) virtualization realization method as well as a vertex data caching method and a related device. The method comprises: a graphics client intercepting vertex array class commands; caching vertex data to create a first cache area, sending a synchronization command to a graphics server to create a second cache area, and the second cache area and the first cache area forming a mapping relationship of the vertex data; querying in local data, packing and sending the vertex array class commands to the graphics server to render a picture according to the vertex data of the second cache area and the packed vertex array class commands if one piece of vertex data consistent with the intercepted vertex data exists in the local data, and if there is no vertex data consistent with the intercepted vertex data in the local data, resolving and sending the vertex array class commands to the graphics server to render the picture according to the resolved vertex array class commands. By doing as above, the present invention enables a drastic reduction of the delay and the bandwidth of transmission paths, and also reduces CPU (Central Processing Unit) consumption of memory sharing, increases VM (Virtual Machine) density and lowers cost.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a GPU virtualization implementation method, a vertex data caching method and related devices. Background technique [0002] GPU (Graphic Processing Unit, Image Processor Unit) mainly performs floating-point calculations and parallel calculations, and is often used for professional graphics operations. GPU virtualization technology is to allow virtualized instances running on data center servers to share the same or multiple GPU processors for graphics computing. Judging from the products that have been implemented so far, the virtualization solution based on DirectX 3d is relatively mature, and it is close to the level of physical machines in terms of performance and experience; More 3D software is implemented based on the Opengl (OpenGraphics Library, an open graphics program interface) specification, and this field is the most urgent application problem that ent...

However, in the remote rendering process, the vertex array pointer intercepted from the application layer is allocated on the graphics client. If the vertex array pointer is directly transparently transmitted to the graphics server for use, an error will occur

Chromium decomposes a glArrayElement instruction call into equivalent glVertex3f, glNormal3f, glColor3f or glTexCoord2f calls, that is, converts the pointer-type parameter instruction of glArrayElement into a series of value-type parameter instructions, and the number of instructions after decomposition is the number of instructions before decomposition. More than 100 times, the amount of data transmitted by the network will increase suddenly, a large amount of delay will be generated, the bandwidth of the transmission channel will be occupied, and the CPU consumption of memory sharing will be increased, resulting in low VM (Virtual Machine ware, virtual machine) density and high cost. high
