Supercomputer service

Introduction

User ID is required for using Supercomputer system. For the details of the application of User ID, please see this page. Each user must apply an individual User ID, and it is prohibited to use other user’s User ID.

Overview of provided service
Basic service (Only User ID is required.)
  • Use of shared nodes for trial and debugging. (a few nodes, up to 1 hour for each job, all user share the computational resources.)
  • Use of Supercomputer storage (home area 100GB)
  • Use of the application server (limited by User’s affiliation): for details, please see this page.
Additional service (Additional application is required.)
  • Use of shared nodes: each user purchases operation time (token), and a job is executed by consuming the operation time (token). Computational resources are shared by among users. A job that needs a large number of nodes can be run.

    Note: The operation time that a job consumes is calculated as the product of the elapsed time and the number of used nodes.

    Example 1: using 1 node and elapsed time 1 hour (3600 seconds) -> 3600 seconds (=1 x 3600)
    Example 2: using 8 nodes and elapsed time 10 minutes (600 seconds) -> 4800 seconds (=8 x 600)

  • Use of fixed-rate exclusive nodes: each user purchases node(s) (yearly amount per node), and the user (and embers of the user’s group) can exclusive use the node(s). User(s) can run jobs without waiting other users’ jobs.
  • Supercomputer storage: each user can apply an additional amount of Supercomputer storage (home and work areas).

*The above additional services can be shared by among members of a group, which consists of Users appointed by the applicant of the additional service.

※1: “######” corresponds to the group’s ID.
※2: Jobs can be simultaneously run until the number of total nodes used by the jobs exceeds the number of purchases nodes.
(i.e. if 8 nodes are purchased, 8 jobs, each job used 1 node, can be simultaneously run.)
