Implementation of high-speed serial interconnects for multi-processor parallel system

Abstract

Multi-processor parallel system is widely used to meet the increasing demand of high-performance computing. However, the data interacting between processors is often a bottleneck as it is hard for parallel buses to address the requirement of transmitting mass data in high speed. Based on differential signal and embedded clock technology, high-speed serial interconnect has been the ideal solution. In this paper, we designed a multi-processor parallel system and implemented the high-speed serial interconnects between processors based on Serial Rapid IO (SRIO), PCI Express (PCIe), and Hyperlink protocols. The test results are given to show the throughput performance of these interconnects.
