The PRIMEPOWER HPC is a new Fujitsu HPC server, which combines the vector parallel processing technology of the VPP Series with the symmetric multi-processor (SMP) technology of the PRIMEPOWER UNIX server. The PRIMEPOWER HPC enables an SMP node configuration consisting of up to 128 high-speed (5.2 GFLOPS) scalar CPUs to be built. As up to 128 processing nodes can be crossbar-connected via a high-speed optical interconnection unit, the maximum configuration of the parallel multi-node system attains a logical performance of 85.2TFLOPS and 64 Tbytes of main memory. Features for high performance include high-speed CPUs, high-speed (133 gigabytes per second) snoop performance, and a barrier synchronization unit, while features for high reliability include redundancy of the node crossbar switch units and partitioning. This paper describes the parallel processing method and hardware features of the PRIMEPOWER HPC.
