Using hierarchical framework , we divide the parallel vector library into four layers based on spmd parallel computing model : application component layer , abstract data layer , data mapping layer and parallel abstraction layer 本文基于spmd并行計(jì)算模型,采用層次式結(jié)構(gòu)模式將并行向量庫(kù)劃分為四個(gè)層次:應(yīng)用組件層,抽象數(shù)據(jù)層,數(shù)據(jù)劃分層和并行支撐層。
