2. Use direction

This indicates the use direction of Supercomputer Fugaku.

2.1. Overview

To start the use of Supercomputer Fugaku, it is required to proceed the following steps describe in “Start up guide”.

• Installation of client certification

• Registration of SSH public key

The following shows a series of flows from program creation and compilation to job execution.

1. Login to the login node

[terminal] $ ssh username@login.fugaku.r-ccs.riken.jp

2. Create a program

[_LNlogin] $ emacs sample.f08

3. Compiling

[_LNlogin] $ frtpx -Kfast,parallel -o sample sample.f08

4. Create a job script

[_LNlogin] $ emacs sample.sh

5. Job execution

[_LNlogin] $ pjsub sample.sh

6. Display a job status

[_LNlogin] $ pjstat

7. Confirm a result

[_LNlogin] $ less ./sample.sh.jobid.out
[_LNlogin] $ less ./sample.sh.jobid.err
[_LNlogin] $ less ./sample.sh.jobid.stats

2.2. Manual

The following manuals are offered in the Fugaku website.

Please refer to “Resource” -> “User’s Guide” or “Manuals” from the menu of the Fugaku website.

If you want to use more detailed functions, please refer to the related manual.
