| Abstract | In this paper, the parallelization of the H.261 video coding algorithm on the IBM SP2 multiprocessor system is described. Based on domain decomposition as a framework, data partitioning, data dependencies and communication issues are carefully assessed. From these, two parallel algorithms were developed with the first one maximizes on processor utilization and the second one minimizes on communications. Our analysiis shows that the first algorithm exhibits poor scalability and high communication overhead; and the second algorithm exhibits good scalability and low communication overhead. A best median speed up of 13.72 or 11 frameskec was achieved on 24 processors. |
