摘要
过去一直用点对点单点传送信息取得屏蔽同步。为了减小屏蔽同步成本 ,近来已提出用多目标蠕虫的方法。本文提出两种快速多目标蠕虫法 ,即对分法和探索法。他们适用于在蠕虫洞路径网络中的完全屏蔽操作或任意部分的屏蔽操作。将这两种方法结合起来 ,得到对分探索法 。
Point-to-point unicast messages have been conventionally used to achieve barrier synchronization.Recently,schemes using multidestination worms have been proposed to reduce the barrier synchronization cost.This paper presents two fast multidestination worm based algorithms,the bisection method and the snoop method,for complete and arbitrary set barrier operation in wormhole routed meshes.A combination of the two techniques,the bisection snoop method,yields best performance.
