传统单一的并行计算模型变得越来越复杂,对并行计算各阶段针对性不强、指导能力差的特点,为此提出了对并行计算模型分层研究的思想,依此把并行计算模型分为并行算法设计模型、并行程序设计模型、并行程序执行模型三个层次,分别给出了各个模型的特点及研究内容.理论分析结果表明,通过分层,每个阶段的模型分工明确,目标单一,指导性强.
The conventional unified parallel computation model becomes more and more complex, which has weak pertinence and little guidance for each parallel computing stage. A layered idea for parallel computation model research was proposed, in which the layered parallel computation model was composed of parallel algorithm design model, parallel programming model and parallel execution model. The properties of each model were described, and research spots were also given. Theoretical analysis results show that the layered parallel computation model is clear and single-goaled for each parallel computing stage.
