Abstract

A GPU simulation method. An instruction sequence of a client GPU is intercepted in a kernel state simulator based on system virtualization and GPU using principle, and a mechanism is selected according to user configuration to accomplish simulation of the client GPU. In first mechanism, instruction translation is accomplished on low-level semantics based on a binary translation technology, and instructions are executed on a host GPU; in second mechanism, instruction conversion is accomplished using an existing GPU software stack, and instructions are executed on host GPU. The method provides an efficient simulated GPU for a virtual machine based on a host machine physical GPU, and solves the problem of slow GPU simulation. Based on a system virtualization technology and by virtue of a convenient condition provided by an existing GPU software stack, the GPU simulation speed is improved, and the implementation difficulty and complexity of the method are effectively controlled.

Dependent claims

A GPU simulation method, comprising the following steps:

step 101:
in a virtual machine, an application program sending a high-level command to a client GPU drive;
step 102:
the client GPU drive converting the high-level command submitted by the application program into a group of low-level instruction sequence that can be recognized by a corresponding client GPU, and then writing the low-level instruction sequence into a client GPU instruction cache;
and
step 103:
the client GPU drive triggering a submission operation after a plurality of associated high-level commands are submitted, wherein the submission operation triggers the virtual machine to exit (VM-Exit), then the control right is transferred to a kernel state simulator, and the kernel state simulator decides on different mechanisms of GPU simulation according to configuration strategies.
