【摘要】 我们最近提出了同型异构计算系统ＨＣＳＭＯＳＴ的概念，将它划分成三大类，并分别推导出它们的加速比模型．本文采用一种不同的应用任务模型来研究其中的第Ⅱ类ＨＣＳ〈０，ｍ，０〉系统，得出它的新加速比模型，并以ＨＣＳ〈０，１８，０〉系统为例，对具有不同并行性分布的计算任务获得的计算结果进行分析讨论．更多还原

【Abstract】 The concept of HCS MOST (Heterogeneous Computing Systems with Machines of the Same Type) has been proposed recently by us.HCS MOST is classified into three classes and the general speedup formulas for them have been introduced.In this paper,with a different application task model,a new speedup model for the second class of them,i.e. HCS〈0,m *,0〉system,is presented.The calculation results derived from computation tasks with different parallelism distribution for an example system HCS〈0,18 *,0〉 are given and analyzed.更多还原
