并行程序设计与并行计算机的体系结构密切相关,因此其复杂性要远远大于串行程序设计.介绍了数据分解和循环体依赖等概念,提出了一个cache利用率和并行计算机有效速度的近似关系模型.通过该模型和一个实例,阐述了在并行程序设计中降低和拆解计算目标中数据依赖的方法过程,从而达到尽可能多地发掘指令级并行性,提高cache利用率即提高并行系统有效速度的目的.
- 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.
