Abstract
This paper describes a new-generation vector parallel supercomputer, NEC SX-9 system. The SX-9 processor has an outstanding core to achieve over 100Gflop/s, and a software-controllable on-chip cache to keep the high ratio of the memory bandwidth to the floating-point operation rate. Moreover, its large SMP nodes of 16 vector processors with 1.6Tflop/s performance and 1TB memory are connected with dedicated network switches, which can achieve inter-node communication at 128GB/s per direction. The sustained performance of the SX-9 processor is evaluated using six practical applications in comparison with conventional vector processors and the latest scalar processor such as Nehalem-EP. Based on the results, this paper discusses the performance tuning strategies for new-generation vector systems. An SX-9 system of 16 nodes is also evaluated by using the HPC challenge benchmark suite and a CFD code. Those evaluation results clarify the highest sustained performance and scalability of the SX-9 system.
