Description
Technical field
The present invention relates to a kind of method that realizes the multiple users share graphics workstation, particularly relate to a kind of virtual desktop technology of using and realize that a plurality of users share the physical resource of graphics workstation, each user has oneself independently desktop; Simultaneously, a plurality of video card transparent transmissions (PASS-THROUGH) on graphics workstation can be distributed and to be transparent to each desktop by means of the GPU Signal Transparent Transmission Technology, make each user have to guarantee utilize virtual desktop and the GPU transparent transmission of the video card capabilities that design is wanted to realize the method for multiple users share graphics workstation.
Background technology
The English full name Graphic of GPU Processing Unit, translator of Chinese is " graphic process unit ".GPU is the concept with respect to CPU, because the processing of (particularly domestic system, the fan of game) figure in modern computer becomes more and more important, needs the core processor of a special figure.
GPU is video card " heart ", also just is equivalent to the effect of CPU in computer, and it has determined class and most of performance of this video card, is also the differentiation criterion of 2D display card and 3D display hardware simultaneously.
At first NVIDIA company proposes the concept of GPU when issue GeForce256 graph processing chips in 1999.
GPU can support T& from hardware; L(TransformandLighting, polygon conversion is processed with light source) display chip because T& L is a pith during 3D plays up, and its effect is calculate polygonal 3D position and process dynamic light effects, also can be called " geometric manipulations ".A good T& The L unit, can provide careful 3D object and senior light special efficacy; In only most of PC, T& Most of computing of L be transfer to that CPU processes (this is so-called software T& namely just; L), because the task of CPU is various, except T& Outside L, also will do the non-3D graphics process work such as memory management, input response, therefore in actual operation, performance can be had a greatly reduced quality, and the situation of video card waiting for CPU data usually occurs, and its arithmetic speed does not far catch up with the requirement of complex three-dimensional game today.Even the operating frequency of CPU surpasses 1GHz or higher, also little to its help, because this is that PC itself designs the problem caused, with the speed of CPU without much relations.
GPU is display card " brain ", and it has determined class and most of performance of this video card, is also the differentiation criterion of 2D display card and 3D display hardware simultaneously.The 2D display chip mainly relies on the disposal ability of CPU when processing 3D rendering and special efficacy, is called " soft acceleration ".The 3D display chip is that 3-D view and special effect processing function are concentrated in display chip, also i.e. so-called " hardware-accelerated " function.Display chip is maximum chip (being also that pin is maximum) on display card normally.
Transparent transmission, be the translator of English of Pass Through, sometimes also referred to as direct transferring.Here refer to and will physically be connected to host, by the display card of host operating system management, from host " solution is tied up ", " articulating ", to virtual machine, by the VME operating system management, just looks like to be the display card that " physically " is connected to virtual machine.
Traditional graphics workstation, at the single single station of needs, except somewhat expensive, be the more important thing is inconvenient long-range use.
To reduce costs in order reaching, simultaneously, realizing any time, any place, the purpose that can access by any equipment, to need can move a plurality of different virtual machines on a host, can realize from concentrated place managing.
