Quick Start Guide¶
This page organizes information for those who have experience using other supercomputer sites, including TSUBAME4.0's unique specifications and rules, which you must understand.
If you are not confident about using UNIX/Linux/supercomputer, please see I'm a beginner, I don't know what to do before reading this page.
If you want to know the overview of TSUBAME4.0, please also refer to "TSUBAME4.0 Guidance" in Seminar text.

About using TSUBAME4.0¶
How to log in to TSUBAME4.0 and precautions for use¶
- Please be sure to read Please refrain from occupying the CPU in the login nodes. and Resource Limit Values before using TSUBAME4.0. Please pay particular attention to the following points. Do not use VSCode Server or Jupyter Notebook to connect to the login node.
- For the procedure of registering SSH public key, please refer to SSH public key registration.
- For information about log in, such as where to connect to the login node, please see "Login".
About job scheduler¶
TSUBAME4.0 uses a job scheduler called AGE (Altair Grid Engine).
For information on how to use it, please refer to Job Scheduler.
About storage¶
The storage provided by TSUBAME4.0 is as follows:
| Directory path | Available members | Paid / free | Kind | Size | Other |
|---|---|---|---|---|---|
| ${HOME} | Account | free | SSD | 25GB | home area |
| /gs/bs | Shared by group | Paid | HDD | Per 1TB | Group Disk |
| /gs/fs | Shared by group | Paid | SSD | Per 100GB | Group Disk |
For information on how to use it, please refer to Storage system.
Notes on using /tmp¶
In TSUBAME4.0, from the perspective of job operation management, use of directories directly under /tmp on the compute node is prohibited, and a tmp area (local scratch area) that can be used by each job is provided as an alternative directory.
The path to the local scratch area is defined in the environment variable ${T4TMPDIR}. (Because the path differs each time depending on the job you submit, be sure to specify it using the environment variable.)
By using the local scratch area, you can achieve the fastest file access without crossing nodes. (However, please note that files in the local scratch area are deleted when the job ends.)
For information on how to use it, please refer to Local scratch area.
About use commercial applications¶
Some commercial applications are available for a fee, and procedures are required to use them. There are some restrictions and procedures that must be followed in order to use Commercial Applications. Please refer to the following first.
Please refer to the following for the procedure for using Commercial Applications.
- Use applications on TSUBAME ... Application Activation
