Parallel Coding Efficiency Analysis of H.264 on PC Cluster

In this paper, we investigate the parallel video coding efficiency on PC cluster. Some important factors that affect the parallel coding efficiency are analyzed: network performance, coding algorithm complexity and parallel mechanism. On Gigabit Ethernet PC cluster, a common MPI-based H.264 parallel video coding mechanism was designed, and a large number of tests and in-depth analysis were performed. Also this paper gives practical data analysis report and advice on how to build high-efficiency parallel video coding system on PC cluster.
