For first-time visitors


Thank you for considering the supercomputer systems of the Information Technology Center, the University of Tokyo (hereafter, “the Center”). This page introduces the characteristics of the supercomputers that are currently in operation and the methods of use. If you have any questions, please contact us through the contact details provided at the bottom of this page.

Characteristics of each supercomputer system

The Center currently operates the Wisteria/BDEC-01 and Oakbridge-CX supercomputer systems. The characteristics of each system are provided here to serve as reference when you are selecting a system. As it is not possible to say, as a rule, which supercomputer is more suitable for a specific purpose, we recommend that you make use of the trial use course described later to try out both supercomputer systems for yourself. For detailed information of each supercomputer, please refer to the linked introductory pages below.

  • 　Wisteria/BDEC-01 Supercomputer System
    • Rich computational resources (7,780 nodes × 48 cores) (Odyssey)
    • Same node as "Fugaku". (Odyssey)
    • 45 nodes with 8 of the latest GPUs per node (Aquarius)
  • 　Oakbridge-CX Supercomputer System
    • Orthodox configuration that combines elements with a high market share, such as Intel CPU and Omni-path.
    • Supports processing that requires high file input / output performance by installing SSD in 128 nodes.
    • Possible to incorporate dedicated HD and cables by applying for fixed nodes

Methods of use

Various methods of use are available for each supercomputer. Please select the method of use that best suits your purpose.

  • 　General use

    • This service is available for individual researchers or research groups at universities and public institutions.
  • 　Corporate use

    • As a part of our social contribution initiatives, some computational resources are also offered to corporations that meet the application criteria.
  • 　wakabaFree Trial Course

    • This service offers the trial use of the supercomputers at no charge.
  • 　Trial

    • This system offers the trial use of the supercomputers at a lower cost than normal. Corporate users may also make use of this system.
  • 　Use by youths/women

    • This program is open to public applications, and is targeted at young researchers (including students) below 40 years of age and female researchers. Selected subjects may use the computational resources they have applied for at no charge.
  • 　Educational use

    • Computational resources are offered for use in undergraduate and graduate classes. Applications from institutions other than the University of Tokyo are also accepted.
  • 　Large-Scale HPC Challenge

    • This program is open to public applications, and allows one research group to monopolize the maximum number of compute nodes of Reedbush-H and Oakforest-PACS for a maximum of 24 hours.
  • 　Use through other public application systems

    • Computational resources are offered by the Center in its position as a HPCI resource provider, and as a Joint Usage/Research Center for Interdisciplinary Large-Scale Information Infrastructures.

Application

The use of the Center’s supercomputers is restricted to eligible users of the Center, and users are required to comply with the terms of use. When applying for use, please read the following “Eligibility for use” and “Terms of use” carefully. Please also refer to the other materials where necessary.

Parallel programming workshop with trial account

Parallel programming workshops that come with a trial account, allowing participants to practice using the supercomputers, are held regularly. New users who are considering the use of the supercomputer systems (including corporate engineers and researchers) are also welcome to participate in these workshops. Through the workshop, participants can gain an idea of how to use the supercomputers through hands-on experience at using the systems, and also learn about parallelization methods. While restricted to the contents covered in the workshop, accounts that can be used for a month are also distributed to participants.
Workshops that correspond to the levels of participants are also held, starting from the introductory session, which requires no basic knowledge about parallel processing, to parallelization at the practical level of numeric calculations. The workshops are free of charge, so please utilize them actively. For details, please refer to the following link.
