Abstract: nboard data system sets up the unified data management and supports the system level reconfigurations by networking all the onboard computers.The criteria for selecting the architecture of onboard data system is presented in this paper.Main architectures for parallel computer systems are briefly compared.This paper concludes that several architectures,such as mesh network and crossbar network,are better than the current single bus architecture widely used.
