Description
Technical Field
The present disclosure relates to computer technologies, and in particular, to a method and a system for load balancing among different applications for multiple video cards.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
In a cloud streaming type service system, 3D applications, games and the like are all run on a GPU server, and in order to save cost, one machine often uses a dedicated motherboard, 4 or 8 or even 10 display cards are installed, and a CPU and a memory of one host are shared, so that hardware cost and cabinet hosting cost can be saved, energy consumption and emission reduction low carbon can be saved, and if only a small part of 3D applications are run, because the CPU and the memory can be concentrated on a small number of the applications, speed can have better experience.
However, in the cloud streaming system, there are some outstanding difficulties: how to fully utilize the rendering capability of a plurality of display cards and balance the computational load of the display cards into a plurality of applications.
The Windows operating system only uses one independent GPU video card for one user session, even if the operating system can identify a plurality of GPU video cards, if no other extra work is done, all started applications can be operated on one independent video card, and cannot be operated on a plurality of video cards through simple setting; at present, under Windows, a certain application is appointed to be rendered by which display card, and no relevant data and mature simple and convenient method exist.
The inventor finds that, in the mainstream cloud streaming (cloud rendering, cloud game, etc.) technology, the following types of methods for realizing load balancing by fully utilizing multiple display cards are mainly used, and many problems cannot be solved:
(1) it is necessary for an application developer to support the API processing of multiple display cards at the time of development by selecting which display card to use at the time of startup. This approach is limited by the necessity for application developer cooperation and requires multiple graphics card compatible work to be done during the programming development phase. The method is difficult to meet the requirement of cloud streaming business, because as a cloud streaming manufacturer, the method is compatible with a plurality of developed and produced software, and the released and widely used applications are unrealistic to require the developers to modify again.
(2) The method is based on a Hook mode for a plurality of API interfaces of DirectX, and comprises the steps of injecting an external DLL into existing 3D applications, modifying internal start logic of the external DLL, dynamically modifying original execution flow of the external DLL when the external DLL calls functions such as D3D11createDevice and the like, and appointing a corresponding GPU video card to enter the applications. The compatibility of the mode to the application is problematic, because the mode is based on the external hanging injection, many applications have reverse injection and reverse external hanging mechanisms, and the mode is not feasible; furthermore, the API functions of the DirectX and the like calling the relevant GPU display card are numerous, and the injection is tried one by one, so that a lot of time is consumed, and the simplicity and stability are not sufficient.
(3) By adopting some virtualization schemes, for example, each GPU is virtually and directly connected to a separate virtual machine, which is more troublesome, and after virtualization, a lot of system resources are used, and a layer needs to be transferred through virtualization, which also causes certain resource loss.
(4) The slave hardware layer connects a plurality of display cards together through the technologies of multi-display card fire exchange, SLI and the like through a hardware connecting line, and the slave hardware layer is used as one display card. However, this mode requires that all the graphics card models must be identical, which has many limitations; on the other hand, after the connection of the two video cards, the performance is not the superposition of the two video cards, for example, the video memory is not the superposition effect, and after the two video cards are connected, the performance effect of about 1.5 video cards can be achieved, which wastes much GPU calculation power.
