面向多核平台的网络应用建模

Modeling Network Application for Multi-Core Architecture

扩展了经典的网络应用建模工具Click,提出了面向基于片上网络(Network-on-Chip,NoC)的多核平台的DClick。定义了Element和报文在分布式系统中的部署方式,根据节点具有独立缓冲资源的特点裁减了Element之间的连接方式,定义了专门的报文节点访问机制,给出了消息驱动的Element调度流程。详细介绍了一种DClick的实现方式,给出了原有的Click库与NoC模拟器协同的方法,证实了DClick的有效性和易用性。

DClick is proposed for NoC （Network-on-Chip） based multi-core architecture by extending the canonical network application modeling tool, called as Click. DClick defines the deployment of elements and packets in distributed system. As the nodes have their own buffers, DClick customs the fashion of connection between elements. It also defines the novel mechanism for packets access. Scheduling of elements is given in message-driven fashion. A implementation of DClick is shown in this paper. It is elaborated how a NoC simulator cooperates with the libraries in Click, by which the availability and efficiency of DClick are proven.
