摘要:

流言是P2P网络中一种有效的信息传播机制。在P2P计算的背景下,我们提出了所谓的进化代理模型的分布式人口为基础的算法,使用八卦作为通信策略,并表示每个人作为一个自我调度的单线程。该模型通过定义一个自适应的刷新率来避免种群中的过时节点,该刷新率取决于网络的延迟和带宽。这种机制平衡了移徙率与追求全球人口一致性的联系的拥挤程度。我们在一个真正的并行系统上对该模型进行了实验评估,并观察了解决方案的质量和算法速度如何随着处理器的数量而变化。

英文摘要:

Gossipping has demonstrate to be an efficient mechanism for spreading information among P2P networks. Within the context of P2P computing, we propose the so-called Evolvable Agent Model for distributed population-based algorithms which uses gossipping as communication policy, and represents every individual as a self-scheduled single thread. The model avoids obsolete nodes in the population by defining a self-adaptive refresh rate which depends on the latency and bandwidth of the network. Such a mechanism balances the migration rate to the congestion of the links pursuing global population coherence. We perform an experimental evaluation of this model on a real parallel system and observe how solution quality and algorithm speed scale with the number of processors with this seamless approach.
