> 中文摘要: 与以往的各种并行计算模型相比,LogP模型更真实、更全面地反映了大规模并行计算机MPC(massivelyparalelcomputers)的特征.鉴于目前见到的LogP模型上的算法都仅局限于给出设计思想,本文尝试用算法语言来描述LogP模型上的完整的可移植算法.文中针对单项播送与求和这2类基本问题,实现了它们在有任意参数的LogP模型上的最优算法,并对其时间复杂度进行了分析.本文研究得到国家863高科技项目基金资助.
Abstract:Compared with other parallel computation models,the LogP model reflects the characteristics of MPC(massively parallel computers)more reasonably.In this paper the authors try to use the LogP model to write portable algorithms for MPC.They first propose a general recurrence formula for the defining of optimal broadcast tree,then design and analysis the complete optimal single item broadcast algorithm and optimal summation algorithm in the LogP model whose parameters may have any given values.
