Abstract: Abstract NEC has just launched its new generation SX vector supercomputer, SX-ACE as the successor model of the SX-9 by aiming at much higher sustained performance particularly for memory-intensive applications. This system is based on the high performance core strategy targeting higher sustained performance. It provides both the world top-class single core performance of 64 GFlop/s and the world highest memory bandwidth per core of 64 GBytes/s. Four cores, memory controllers, and a network controller are integrated into a processor as a single LSI, enabling the processor performance of 256 GFlop/s and the memory bandwidth of 256 GBytes/s. Moreover, in order to boost the performance of memory-intensive applications, each core is designed to utilize the whole memory bandwidth of the processor (256 GBytes/s). This brand-new system is quite beneficial to real scientific and engineering applications.
