| Abstract: | There are two bottle-necks in scalable parallel processing systems:(1)Thetransmission delay in interconnection network, and (2) The throughput capability.According to the characteristics of SPP architecture and practical requirements, this paperproposes to add special I/O processors between servers and SM/SSM to realize highspeed transfering, thus improving I/O performance.This method not only eliminatesthe transmission delay, but also supports parallel execution. between processors andDMA controllers. |
