摘要:
提出基于光分组交换及组播的新型高性能计算机系统,分析了系统冲突产生的原因.提出基于循环光纤延时线(Rec-FDL)的冲突解决方案,建立了该结构解决系统冲突时的稳定性及时延模型.比较了Rec-FDL与分组重传冲突解决机制的稳定性及时延特性.Rec-FDL架构所接入的CPU及从节点分组到达率比分组重传机制分别多了400和100 packets/s,具有更高稳定性; 分组到达率为500 packets/s时,若CPU与控制节点距离大于20 km,Rec-FDL架构在输出端口产生的时延比分组重传机制至少小4.5 ms; 若增至50 km,Rec-FDL架构在系统内部产生的时延比分组重传机制小5 μs.Rec-FDL架构更适于构建分布式HPCS及大范围的网格计算网络.
Abstract:
A novel high performance computing system based on OPS(optical packet switching)and optical multicast is presented. System collision reasons are analyzed. A collision resolution mechanism based on recycling fiber delay line(Rec-FDL)is presented and the stability and delay model related to the mechanism are established. Stability and delay relating to Rec-FDL structure and packets retransmission mechanism have been compared. Rec-FDL structure is more stable because packet arriving rate from CPU and standby node in Rec-FDL structure can be 400 and 100 packets/s bigger than that in packets retransmission mechanism; when the packet arriving rate is 500 packets/s and the distance between CPU and control unit is more than 20 km, delay in output-port induced by Rec-FDL structure is 4.5 ms lower than that with packets retransmission mechanism, while it is 5 μs lower inside the system when the distance increases to 50 km. Rec-FDL structure is more suitable for designing distributed HPCS(high performance computing system)and large-scale grid computing network.
