Abstract:: Parallel programming is closely related to the architecture of parallel computers, so its complexity is much greater than serial programming. The concepts of data decomposition and cyclic body dependence are introduced, and an approximate relationship model of cache utilization and effective speed of parallel computer is proposed. Through this model and an example, the method process of reducing and disassembling the data dependence in the computing target in parallel programming design is described, so as to achieve the purpose of exploring as much instruction-level parallelism as possible, improving cache utilization, and improving the effective speed of parallel system.
