基于异步光分组交换的高性能计算机系统
Asynchronous optical packet switching based high performance computing system
摘要
Abstract
An asynchronous optical-packet-switching and optical-multicast based High Performance Computing System (HPCS) with multistage distributed management features is presented, which can process the massive burst services and realize all-optical scalability. A compact and huge-capacity Recycling-Fiber-Delay-Line (Rec-FDL) based collision resolution mechanism is proposed to resolve the contentions for asynchronous arriving packets, and its performances are compared with the traditional Packet Retransmission Algorithm (PRA). The system analysis models for the stabilities, packet loss rates and average packet waiting latencies of the PRA(Trerans) and Rec-FDL (TRec-FDL) schemes are built. The simulations show that, for a two-stage system with 40 320 CPUs, TRec-FDI. is fixed as 0.004 ns, while Trerans increases with the packet transmission distance D, and equals to 0.006 ns and 0.01ns when D is 10 m and 20 m, respectively. Hence, as the HPCS is typically highly distributed, the Rec-FDL scheme can induce lesser latencies than the PRA.关键词
