Abstract

The present disclosure relates to a method for accessing a memory of a graphics processor, a computing device, a computing system, and a storage medium. The method includes: obtaining an access command about the graphics processor, the access command at least indicating the memory address offset data of the accessed target graphics processor; analyzing the data stored in the extended bit of the base address register associated with the target graphics processor identification data, so as to determine the format of the memory of the target graphics processor based on the identification data; based on the determined format of the memory and the memory address offset data, calculate the target address offset; and based on the base address of the memory of the target graphics processor and the The computed target address offset, addressing the memory of the target GPU. The present disclosure is capable of accessing GPU memory in a variety of different formats.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of information processing, and more specifically relate to a method for accessing a memory of a graphics processor, a computing device, a computing system, and a storage medium. Background technique [0002] Graphics processing units (GPUs) are typically configured with large amounts of local memory. Both the central processing unit (CPU) and other devices (such as network cards) need to access the local memory of the graphics processor to complete computing tasks on the GPU. The local memory configured by the graphics processor includes, for example, double data transfer rate memory (Graphics Double Data Rate, GDDR) and high-speed memory and high-bandwidth memory (High Bandwidth Memory, HBM). [0003] A traditional solution for accessing the memory of a graphics processor (for example, a method for the CPU to access the GPU memory) includes: the CPU uses the GPU PCIe Memory Bar to ac...
