To access to our center's high-performance computing environment, users need to access the CMC-Scinet, the supercomputer network which our large-scale computer systems are connected. For the access to our systems, " Login node " and " Frontend node " are installed.
Basic access to our large-scale computer systems is though the login to Login node as the gateway from outside the CMC-SCinet using SSH and GSI-SSH. After logging in, users are automatically connected to the Frontend node as the working computing server. Users can develop and compile their own programs as well as submit jobs through the scheduler.
(note) Part of these nodes have both functions of the Login node and the Frontend node.
(caution)Login is different for HPCI and JHPCN users. Please see below:
How to login (HPCI)
Connecting the host and other information is as follows:
|OS Japanese character code||UTF-8|
Login from Windows system
How to connect to the Login node from Windows is described below:
The SSH (Secure Shell) client must be installed to access the Login node from a Windows platform computer. Several options exist, but we show the case of using Tera Term to access the Login node.
Please download and install Tera Term from Tera Term official site.
1.Start Tera Term and then connect to the Login node
Just click "OK" button after completing the configurations.
Please choose one from three hosts.
2. The following message will appear in your first connection.
Check [このホストをknown hostsリストに追加する] and click the [続行] button.
※ If not checked, this message will appear every time you connect.
3. After configuring the following items on SSH authentication screen, Click the [OK] button.
|user name||User ID|
|Use plain text||check|
4. Connecting the Frontend node that you chose at 1.
When using application on X server environment,
open「設定」→「SSH 転送」 under the TeraTerm configuration,
5. Check [リモートの(X)アプリケーションをローカルのXサーバに表示する] and click the [OK] button.
* This configuration will be valid. You will need to save the configuration from「設定」→「設定の保存」.
Login from UNIX-based OS（Linux, MacOS X, etc）
How to connect to the login node from a UNIX-based OS platform.
Please install ssh by yourself or ask an administrator if the SSH is not installed.
Connect to Login node using the ssh command.
The following is an example to connect to octopus. (user ID:a61234):
% ssh octopus.hpc.cmc.osaka-u.ac.jp -l a61234
In the case of using any application on X server,
% ssh -X octopus.hpc.cmc.osaka-u.ac.jp -l a61234
Typing yes after the following message appears when you first connect to Login node.
The authenticity of host 'octopus.hpc.cmc.osaka-u.ac.jp (220.127.116.11)' can not be established, but keys of different types are already known for this host.
The RSA key fingerprint is 19:14:7f:28:54:39:16:9a:99:d0:db:93:d6:ff:f3:13.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'octopus.hpc.cmc.osaka-u.ac.jp,18.104.22.168' (RSA) to the list of known hosts.
You are prompted to ask for your password. The connection is complete after typing in the correct password.
