Abstract :
Symmetric Multiprocessor (SMP) system and cluster of SMPs have become widely available as cost-effective parallel platforms. In this paper, the comparison of Motion Estimation (ME) algorithms implemented on SMP system and cluster of SMPs was evaluated. The same parallel program written using MPI (Message-Passing Interface) programming model with different compilation procedures were implemented. Results show that the parallel ME algorithms scales well for SMP system (up to 6 processors) and cluster of SMPs (up to 23 processors). In terms of price/performance ratio, it is preferable to have a node with dual-processors than single-processor.
