HPCI User's Guide

This page explains how to use Academic Center for Computing and Media Studies, Kyoto University (ACCMS) for HPCI.

For those who have completed registration for use of our supercomputer, we will send a Notification of the Registration Completion by email. Once you receive the Notification of the Registration Completion, please follow the Procedure to Start the Service.

The user ID notified in the “Notification of the Registration Completion” is used for the purposes shown in the table below. It may fall into both categories. You can confirm the primary center and computing resources from HPCI online application system .

Category Usage of user ID
Those who designate Kyoto University as the primary center Use this user ID as a HPCI account when WEB authentication is required, such as issuing a certificate.

Please refer to the Manual provided by HPCI on how to issue client certificates and log in. The host names for using Kyoto University computing resources are as follows. We will process the registration process to allow you to log in after the issuance of the client certificates. Please wait 15 minutes to log in.

System Host
System A camphor.kudpc.kyoto-u.ac.jp

HPCI uses client certificates to log in to resource providers via SSH (GSI-SSH) with GSI authentication (Grid Security Infrastructure).

Kyoto University computing resources provide the gsissh command and myproxy-logon command required for GSI-SSH.

Users who are available for Kyoto University's computing resources can log in to other system institutions via Kyoto University's computing resources without building an environment for HPCI by referring to the page here. In that case, please use myproxy-logon (obtain a proxy certificate) and the gsissh command as follows

## obtain a proxy certificate (please replace hpci00XXXX with your own HPCI-ID)
$ myproxy-logon -s portal.hpci.nii.ac.jp -l hpci00XXXX

## Log in to other resource providers{#login_of_other_facility}
$ gsissh host01.example.jp

Please refer to Access for how to use the system. The system available for HPCI is System A.

To use HPCI's computing resources, the following queue name must be specified when submitting jobs in batch. Please refer to Batch Processing on how to use the batch system, .

The HPCI proposal ID included in the queue name is the ID of the proposal that was firstly approved.

Classification System Type Queue Name Number of Nodes (FY2024) Notes
HPCI A All year use hpa 106 Nodes Shared by HPCI users. Please do not occupy for a long period of time, as it will be shared and used for multiple proposals.
HPCI-JHPCN A All year use jha 26 Nodes Shared by HPCI-JHPCN users. Please do not occupy for a long period of time, as it will be shared and used for multiple proposals.
HPCI-JHPCN A Intensive use jhXXXXXXa - Please replace hpci00XXXX with your own HPCI-ID. The period of use will be notified individually to the proposal representatives.

At Kyoto University, we use the same login ID (user number) even when multiple proposals are approved by HPCI. Please switch proposals by explicitly specifying the queue name and group name when submitting jobs in batches.

The example below is a sample of the job script required to submit a batch job. The queue name is specified as jha with "#SBATCH -p".

$ cat sample.sh  
#!/bin/bash 
#============ Slurm Options ============ 
#SBATCH -p jha
#SBATCH -t 2:00:00
#SBATCH --rsc p=4:t=8:c=8:m=1800M  
#============ Shell Script ============ 
srun ./a.out

The storage paths of Kyoto University available for HPCI proposals are as follows. /LARGE0, /LARGE1 combinations are available. The available LARGE areas are notified by e-mail to the proposal representative and the contact person.

Available capacities per proposals are as follows

Proposal Available Capacity
HPCI proposal uses System A Listed in the Large Disk column of the Resource Offer Notice (Allocate half to /LARGE0 and /LARGE1)
HPCI-JHPCN proposal uses System A Listed in the Large Disk column of the Resource Offer Notice (Allocate half to /LARGE0 and /LARGE1)

/LARGE1 is the backup destination for /LARGE0 by default. /LARGE1 is available by removing the backup. To change your backup settings, please contact us via the Inquiry Form.

In addition to this, home directories are available up to 100 GB. For more details on how to use storage, please refer to Using the File System.

The mount points for users of the proposals for which HPCI shared storage is available are as follows. Please refer to the HPCI Shared Storage User Manual for details on how to use.

You can confirm the usage status by logging in to the User Portal, clicking on HPCI in the left menu from the Statistics section of the upper menu.

If you divide the value of core elapsed time (in seconds) by 3600 and set the unit to "hours" and divide by 112 (the number of cores per node in System A), you can calculate the actual utilization against the node time of the available quota. Please note that information on all users who can use the queue is displayed on this page, so it is necessary to compare the total value with the time allocated for the proposals.

HPCI has a management system for users of the HPCI system to share information and documents from each system institutions.
