Probing the Heterogeneity Problems for Information Systems;
探索信息系统的异构性问题
Considering the fact that parallel program structure can induce the randomcity of tasks computing and communication cost,the definition of stochastic directed acyclic graph(DAG) was expanded,in which the heterogeneity and the parallel program structure were considered together.
针对并行程序结构产生任务计算量和通信量随机性的情况,提出了一种扩展的随机DAG(Directed Acyclic Graph)模型,同时考虑了计算环境异构性和并行程序结构带来的计算时间和通信时间偏移量;基于此扩展的随机DAG,给出了DAG中节点的EST(Earli-est Start Time)和偏移量的计算方法,以标准方差和平均值的和的数学期望来表示;最后,给出了基于扩展随机DAG的并行程序建模方法,通过计算实例验证了该扩展的合理性。
In the Internet environment,an application layer multicast system s efficiency is influenced by the heterogeneity of the hosts capacities.
在Internet环境下,应用层组播系统的效率受到用户能力异构性的影响,但是在组播结构建立时,结点的能力难以准确得知;因此,提出一个可以在组播结构建立后优化组播树的应用层组播协议SmartTree。
A hierarchical 160-bit ID space is constructed based on the node\'s location information(network heterogeneous) and the node\'s processing capability(node heterogeneous).
基于节点位置的不同(网络异构性)以及节点处理能力的不同(节点异构性),构建了层次化的160位的ID空间;将ID的层次结构与网络的层次结构对应一致,解决了网络拓扑意识一致性的问题;通过加权信誉值的传递,实现了"关键数据"在P2P系统中的存储与收集,动态选择出提供服务的超级节点和"合法"的数据对象。
