Abstract

The invention discloses an implementation method, system and device for the virtualization of a GPGPU (General Purpose Graphics Processing Unit) to solve the problem that the virtualization of the GPGPU cannot be solved in the prior art. The implementation method comprises the following steps: a first virtual machine reads data to be processed in a shared memory of a bus, wherein the data to be processed is written by a second virtual machine; and the first virtual machine invokes a CPU (Central Processing Unit) driver interface, sends the data to be processed to a physical display card for calculation, collects calculated results, and inputs the results in the shared memory of the bus to be read by the second virtual machine. As the first virtual machine can visit the physical display card, and can realize information interaction with the second virtual machine, the virtualization of the GPGPU is realized.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a method, system and device for realizing virtualization of a general purpose graphics processor (General Purpose Graphic Process Unit, GPGPU). Background technique [0002] With the development of graphics processing technology, a professional graphics processor GPGPU that can perform general computing tasks has emerged. GPGPU can execute general computing instructions that are not related to graphics processing. In the face of Single Instruction Multiple Data (SIMD) and the amount of data processing calculations is far greater than the demand for data scheduling and transmission, the computing power and memory access bandwidth of GPGPU far exceed that of the central processing unit ( CPU), thus forming a new heterogeneous architecture of CPU+GPGPU. This new architecture shows strong performance advantages, and has lower power consumption and heat dissipation tha...
