摘要
1引言
从硬件上看,机群系统是由若干独立的高性能计算机(结点机)和起互连作用的高速网络组成的,各个结点间通过传递消息实现结点间的通信.因此,内部互联网络性能的优劣极大地影响着机群系统整体性能的好坏.
The performance of a router chip is crucially influenced by its link arbitration policy. In this paper,the LR-SP(Least Recently Served Preference) link arbitration policy and its implementation applied to the Dawning-UX8 routing chips are presented. Practical results show that this policy provides equality of bandwidth for each Output channel and the implementation method is robust and reliable with low latencies.
