Picture-oriented multi-GPU rendering system, method and device and storage medium

The invention relates to a picture-oriented multi-GPU rendering system, method and device and a storage medium, which are used for improving the throughput and execution efficiency of large-scale rendering tasks. The system comprises a plurality of rendering nodes, each rendering node comprises at least one CPU, each CPU carries a plurality of GPUs, the CPUs and the GPUs are interconnected through communication buses in the rendering nodes, and the CPUs between the rendering nodes are interconnected through a communication network; wherein the CPU is used for receiving a rendering task allocated to a rendering node where the CPU is located, dividing the rendering task into a plurality of rendering sub-tasks, creating a rendering process for each rendering sub-task, generating a rendering instruction based on the rendering sub-task in each rendering process and submitting the rendering instruction to the GPU of the rendering node where the CPU is located; after receiving a rendering result returned by the GPU,
