摘要
This paper presents many real data tests for comparisons, and analyzes various factors accordingly which affect the computation efficiency of parallel algorithm. The comparisons tell that the bigger the computation workload in a parallel processing job is, the higher the processing efficiency is; but the processing efficiency of parallel computation cannot increase linearly. With the increase of processing jobs, the acceleration of computation efficiency will slow down gradually and an inflexion will occur at the optimum degree of parallelism.
