Based on our Fibre-Channel Token-Routing Switch-Network, a high performance/price ratio cluster computing platform is put forward and developed for simulation design which needs large-scale parallel computation. According to the feature of our cluster computing platform, the cluster computing software platform is proposed and implemented. The cluster computing software platform has two parts: the cluster management scheduling sub-platform and the cluster tasks running sub-platform. The cluster management scheduling sub-platform is composed of the cluster management system and the task scheduling system, and the cluster tasks running sub-platform includes the FC-TR communication software and the FC-TR parallel programming environment. The FC-TR communication software provides high-bandwidth, low-latency communication services for the parallel programming environment on the upper layer, while the parallel programming environment makes a number of large-scale-computation simulation design applications run on our network seamlessly. The experiment results show that our cluster computing platform has achieved better performance than the Scali cluster computing platform.
