Supercomputer
A New Era of Research Pioneered by "AFI-NITY Ⅱ"
The “Integrated Supercomputation System,” which currently consists of the distributed memory type parallel computing system, the shared memory parallel computing system, fluid-data analysis server, 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, August 2018, and August 2024. 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, 447 nodes of HPE CRAY XD2000 are used as the distributed memory type parallel computing system, while the shared memory parallel computing system consists of HPE SuperdomeFLEX 280, providing a total peak performance of 4.4 PFLOPS together with fluid-data analysis server, maximum shared memory of 6 TB, and total storage capacity of 223 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).
