Fujitsu Receives Order from Kyushu University for New Top-Class Supercomputer System

System features high-speed interconnect EDR InfiniBand™ connecting over 2,000 servers equipped with Intel® Xeon® processor Scalable family (codename: Skylake)

Fujitsu Limited

Tokyo, June 15, 2017

Fujitsu today announced that it has received an order from the Research Institute for Information Technology at Kyushu University for a new supercomputer system, which will steadily ramp up operations starting in October 2017.

This system will consist of over 2,000 servers, including the Fujitsu Server PRIMERGY CX400, the next-generation model of Fujitsu’s x86 server. It is expected to offer top-class performance in Japan, providing a theoretical peak performance of about 10 petaflops (1). This will also be Japan's first supercomputer system featuring a large-scale private cloud environment constructed on a front-end sub system, linked with a computational server of a back-end sub system through a high-speed file system.

The Research Institute for Information Technology will use this system as computational resources for JHPCN(2) and HPCI(3), as well as a variety of user programs. By making this system available to users both inside and outside of the university, it will enhance the platform for academic research in Japan and contribute to the development of new academic research including AI. Fujitsu will use the technology and experience it has developed as Japan’s top supercomputer maker to strongly support the activities of the Research Institute for Information Technology.

Background of the New System Implementation

As a center for education and research, Kyushu University is the largest public university in the Kyushu region, and the Research Institute for Information Technology is a nationwide joint-use facility visited by professors, graduate students, and researchers across Japan for academic research.

Currently, the Research Institute for Information Technology operates three systems: a supercomputer system (consisting of the Fujitsu Supercomputer PRIMEHPC FX10 system), a high-performance computational server system (made up of Fujitsu PRIMERGY CX400 x86 servers), and a high-performance applications server system. The three systems will be integrated as part of the new supercomputer system, creating an environment that can meet an even wider variety of needs, extending beyond the current large-scale computation and scientific simulations, to include usage and research that require extremely large-scale computation, such as AI, big data, and data science.

Features of the New System

1. Server System

The server system of the new supercomputer system will consist primarily of a back-end subsystem, a front-end subsystem, and a storage subsystem.

Back-end subsystem
The computational nodes will be made up of 2,128 PRIMERGY CX400 systems, the next-generation model of Fujitsu’s x86 server, equipped with Intel® Xeon® processor Scalable family (codename: Skylake). 128 of these servers will be equipped with four NVIDIA® Tesla® P100 GPU computing cards each (a total of 512 cards/ NVIDIA® NVLink™ (4) used to connect GPUs).

Front-end subsystem
This system will consist of 160 basic front-end nodes featuring Intel® Xeon® processor Scalable family (codename: Skylake) and NVIDIA® Quadro® P4000 graphics cards, as well as four high-capacity front-end nodes featuring 12 terabytes of memory each, and other servers.

Storage subsystem
Fujitsu will deploy a disk array system with an effective capacity of over 24 petabytes.

2. Interconnect

Using the latest high-speed interconnect EDR InfiniBand™ to connect between the servers, this system offers high parallel computation performance and availability.

3. File System

This supercomputer system will be built using FEFS(5), Fujitsu's high capacity, high performance, high reliability distributed file system with a proven track record both inside and outside Japan.

4. Power Saving Feature

This will incorporate a system to monitor electricity usage. By using the Fujitsu Software Technical Computing Suite(6), the HPC middleware, this system will flexibly control electricity usage through such functions to limit the maximum electricity consumption for each system user.

Comment from Rin-ichiro Taniguchi, Director of the Research Institute for Information Technology at Kyushu University

Currently, HPC research technology connected with open data and AI technology is an emerging field. In addition, high performance computing with restrictions on power usage will be an important technology development field. In the midst of an HPC field that is on the cusp of major changes, we expect that this new system will be infrastructure that is up to such challenges and will lead to many academic and practical contributions.
