DATA TRANSMISSION AND TASK PROCESSING METHODS, APPARATUSES AND DEVICES

摘要

Data transmission and task processing methods, apparatuses and devices. A solution comprises: obtaining a data transmission request sent by a client (302); obtaining a first virtual address in the data transmission request (304); obtaining a physical memory address corresponding to the first virtual address (306); on the basis of a mapping relationship between the physical memory address and the virtual address, determining a second virtual address corresponding to the physical memory address (308); obtaining a GPU address allocated for the data transmission request (310); generating a data copying instruction from the second virtual address to the GPU address (312); and calling an interface driven by the GPU to execute the data copying instruction (314).
