There is much waste of computing resources in cluster, such as setting aside multi-core CPU, underutilization of GPU, separating the use of CPU and GPU. To use CPU and GPU better, some technologies, such as multicore CPU processing, GPU parallel processing and CPU + GPU integrated processing, are researched in this paper. A CPU + GPU cluster parallel display system is presented to improve the parallel display capability of cluster tiled system. The experimental results show that the CPU + GPU cluster parallel display system presented is feasible and can greatly improve the display speed of massvie information.
