CHY-Ⅲ通讯库的设计——一种面向并行仿真程序的可伸缩通信缓冲申请算法

CHY Ⅲ Communication Library Design

从并行仿真程序的特点出发，为了解决点对点消息传递系统中由于网络热点（ＨｏｔＳｐｏｔ）而引发的消息阻塞问题，充分利用仿真程序的帧特性，设计实现了一种可伸缩的通信缓冲区申请算法，用软件方法消除了由阻塞而引起的死锁现象。经试用表明该算法开销小。

Based on characteristics of parallel simulation program, in order to solve the block problem of point to point message passing system caused by hot spots and make full use of the frame characteristic of simulation program, this paper puts forward a scalable communication buffer requesting algorithm realized on CHY Ⅲ. The algorithm eliminates dead lock phenomena caused by blocking by means of software method, and proved to be of high efficiency and low cost.
