Cloud rendering system, server and method

Abstract

The invention discloses a cloud rendering system which comprises a host machine and multiple GPUs.The host machine is provided with multiple virtual machines.Each virtual machine is provided with one corresponding GPU drive.The cloud rendering system further comprises an MMU coupled to each GPU drive and each GPU and coupled with virtual machine internal storages and a host machine internal storage, and an IOMMU coupled to each GPU and the virtual machine internal storages.When any virtual machine makes a request for getting access to the GPUs, the MMU distributes one GPU address to the GPU drive of the virtual machine, wherein the GPU address is used for getting access to the GPU; when any virtual machine makes a request for getting access to the virtual machine internal storage, the MMU distributes the corresponding host machine internal storage address to the virtual machine; when any GPU makes a request for getting access to the virtual machine internal storage, the IOMMU distributes the corresponding host machine internal storage address to the GPU.According to the system, by configuration of the MMU and the IOMMU, the multiple virtual machines can get direct access to the GPUs independently.Compared with a Nvidia VGPU architecture generally adopted in the prior art, the system is low in price and high in rendering performance.

Description

technical field [0001] The present invention relates to the technical field of GPU virtualization, in particular to a cloud rendering system, server and method. Background technique [0002] Cloud computing has become more and more popular, and more and more manufacturers are considering transferring their business to cloud hosts (such as virtual machines and container virtualization) of cloud service providers. However, the current cloud hosts cannot provide strong 3D rendering capabilities and GPGPU (General Purpose GPU) computing capabilities to support applications with strong 3D real-time rendering requirements and high-performance computing applications. At present, cloud service providers mainly rely on cloud services The management platform, virtualization software, and hardware support virtualization technology, cut, isolate, and package physical resources into cloud hosts, and provide external services based on this. Due to the complexity of GPU (Graphics Processi...

Problems solved by technology

However, most of the virtual machines in this method do not directly communicate with the GPU, but send the rendering request to another predetermined virtual machine to complete the rendering task on their behalf, so the computing efficiency and rendering ability will not be very high

[0005] To sum up, none of the existing cloud rendering technologies enables virtual machines to directly access the hardware GPU for rendering, and the existing cloud rendering devices are expensive and have poor 3D rendering performance
