In order to analyze the quality of the massive H264 videos in the 3G network, we set up a GPU cluster to decode the multi-videos on CUDA and evaluated the clarities of the decoded frames. This paper focuses on parallel intra prediction and its optimization. By improving parallel algorithm, adjusting data structure and rationally using multilevel memories of GPU, we show that these operations achieve...
In order to solve the parallel processing problem of mass data, stream processor develops quickly in recent years. The essence of stream processor is getting high performance according to executing thousands of threads parallelly. It is widely used in scientific computing, data mining, video quality analysis and other fields. But mass threads means the high costs of thread synchronization. Mass computing...
