Integrated Supercomputation System

The “Integrated Supercomputation System,” which currently consists of the distributed memory type parallel computing system, the shared memory vSMP parallel computing system, the Three-dimensional Visualization System for vislualization of computation results, and the Measurement Integration Interface Server to link the supercomputer and experimental measurement system, started operation in November 2005 and was updated in May 2011, May 2014, and August 2018. The data storage system (magnetic disk), which has petabyte class capacity, is connected to the servers using a storage area network (SAN). The Realization Workspace and peripherals with stereo visualization devices are also involved in the system. For the supercomputing servers, Fujitsu servers based on Primergy are used as the distributed memory type parallel computing system and the shared memory vSMP parallel computing system, providing a total peak performance of 3.7 PFLOPS, maximum shared memory of 16 TB, and total storage capacity of 192 TB. The network which connects the servers and users has a 40 Gbit Ethernet as the backbone, and facilitates clients’ work, including high-speed data transfer and image processing at each laboratory in the Institute of Fluid Science (IFS).


Leading next-generation fluid science research through the integration of large-scale computing and experimental measurement

The supercomputing servers3.7PFlops

  • Realizes total peak performance improvement on total theoretical computing performance of 3.7 PFlops (about 24 times the old system), with full-scale introduction of a distributed memory type parallel computing system
  • Utilizes the numerical resources of the institute by introducing a large-scale shared memory vSMP parallel computing system
  • Leading in cutting-edge supercomputing in the field of fluid science

Three-dimensional visualization system

  • Japan’s first tiled display system consisted of 12 (3x4) 70-inch full HD(1920x1080) displays
  • Realizes an unsurpassed immersive feeling by combining stereophonic sound and motion capture ? a VR system, effective in both outreach and research, that enables dynamic understanding of complex flow phenomena

External storage device19PB

  • Large capacity storage of 19 PB total (about 3.4 times the old system) for free handling of vast amounts of fluid information
  • Spatiotemporal analysis of large-scale time series data, to explore previously unknown complex flow phenomena, and development of control and design methods for various flow phenomena ? advances that will help achieve sustainable development of human society

Measurement-Integrated Simulation

  • Implementation of high-speed data transfer by directly connecting experimental facilities and supercomputing servers in a high-speed network (InfiniBand)
  • Promotion of research on fluid science in advanced fusion areas, such as elucidation of blood flow in living bodies and control of plasma flow in semiconductor manufacturing using the world-leading “Integrated Supercomputing Method,” a technique that unifies experimental findings and supercomputer computations
