Predictive multiplexed switching is a new approach for building interconnection switches for high performance parallel systems. This approach advocates sacrificing some link bandwidth in return for more efficient network control and simpler connection management. The main idea is to depart from the traditional packet and wormhole switching in favor of row(More)
This paper presents an efficient hardware architecture for scheduling connections on a fat-tree interconnection network for parallel computing systems. Our technique utilizes global routing information to select upward routing paths so that most conflicts can be resolved. Thus, more connections can be successfully scheduled compared with a local scheduler.(More)
The maximum matching algorithm for bipartite graphs can be used to provide optimal scheduling for crossbar based interconnection networks. Unfortunately, maximum matching requires <i>O</i>(<i>N</i><sup>3</sup>) time for an <i>N</i> x <i>N</i> communication system, which has limited its application to real-time network scheduling. In this paper, we show how(More)
This paper introduces a framework for the design, synthesis and cycle-accurate simulation for parallel computing networks of 128+ processors. In order to accurately characterize the network, we present a bottom-up design methodology in which each of the components are designed using a hardware description language and synthesized to an FPGA for performance(More)

Review and summarize the published literature since 1994 on treatment of anxiety neurosis with acupuncture and moxibustion, so as to provide evidence for standard acupuncture and moxibustion treatment program. It is indicated that Baihui (GV 20), Neiguan (PC 6), Shenmen (HT 7), Sanyinjiao (SP 6), Yintang (EX-HN 3), etc. were the most commonly selected for(More)
