Each of the Fujitsu systems included in the TOP500 list has a distinct architecture, all designed to achieve superior efficiency in execution:
1. Rank 34 - Kyoto University - T2K Open Supercomputer (HX600 Technical Computing Server) - Quad-core AMD Opteron (AMD64) - 50.510 teraflops - 82.49%
2. Rank 172 - Kyushu University - Supercomputer System (PRIMERGY RX200 S3 PC Server) - Intel Xeon (Intel64) - 15.090 teraflops - 81.87%
3. Rank 335 - Kyushu University - Supercomputer System (PRIMEQUEST 580 Mission Critical IA Server) - Intel Itanium2 (IPF) - 10.850 teraflops - 82.78%
Extremely high performance and efficiency for the three distinct architectures was achieved by combining Fujitsu's high-performance hardware with its software development technologies such as Parallelnavi, a middleware package for high-performance computing (HPC), which helps extract the hardware's maximum potential, and its system integration technologies.
Fujitsu is the only company in the TOP500 list using AMD's AMD64, Intel's Intel64 and IPF architectures and to obtain 80% efficiency or better from all of them.
