• 論文抄録 / 内容記述: Existing supercomputers have taken their custom network architecture to their specific network topologies. This study exploits a systematic topology-agnostic network design (TAD), which is radically different from the existing network architecture. The topology-agnostic network design uses a solution of the order/degree graph problem (ODP) as a network topology to minimize the average communication latency. It then takes a topology-agnostic floor layout, deadlock-free routing, collective communication, fault-tolerant technique, and job mapping since different graphs are ODP solutions depending on given degrees and the number of nodes. The result interconnection networks improve multiple communication performance metrics of supercomputers: up to 75% reduction of maximum zero-load communication latency, 18x bisection bandwidth, and 18% reduction of job turnaround time. Their negative aspect on long cabling could be limited on the cost and the power consumption with modern active optical cables.
