捕获不同计算机体系结构特征的参数化通用模型将促进可移植程序的开发。通过指定通用模型的参数，可以得到适合于特定计算机的特定模型。通用模型应该是简单的，并且对于它打算表示的每台机器，它应该有一个相当准确的特定模型。并行内存层次（PMH）计算模型使用单一机制来模拟处理器间通信和内存层次流量的成本。计算机被建模为一棵内存模块的树，处理器位于树的叶子处。所有数据移动都采用子节点和父节点之间的块传输形式。本文评价了PMH模型作为通用模型的优缺点
A parameterized generic model that captures the features of diverse computer architectures would facilitate the development of portable programs. Specific models appropriate to particular computers are obtained by specifying parameters of the generic model. A generic model should be simple, and for each machine that it is intended to represent, it should have a reasonably accurate specific model. The Parallel Memory Hierarchy (PMH) model of computation uses a single mechanism to model the costs of both interprocessor communication and memory hierarchy traffic. A computer is modeled as a tree of memory modules with processors at the leaves. All data movement takes the form of block transfers between children and their parents. The paper assesses the strengths and weaknesses of the PMH model as a generic model.>
