Abstract: This paper gets the speedup rate and efficiency formula of two typical kinds of grid computing system. It can provide a theory basis to construct a distributed and parallel computing system and estimate the efficiency of one task allocation algorithm. It provides a foundation for forward research on distributed and parallel system or grid computing system.
