How to use Computing Server for graduate students (csgs2 system)

(2021/06/25) The operation of csgs1 system was discontinued by Thursday, June 24th. Thank you for your understanding.


(2021/05/21) The operation of new server (csgs2 system) was started.


As a general rule, csgs2 system is restarted once a month (early morning on the first day of every month) for system maintenance.

In addition, it may be stopped or restarted without notice due to security problems, urgent system maintenance or other unexpected accidents. 

*  For programs that calculate over a long period of time, take measures such as dividing the program size appropriately and outputting the progress to a file so that the calculation results are not lost.

In addition, the csgs2 system is not intend for file services, so please do not place any files other than those required for calculation. Thank you for your understanding. (The total disk space is not large enough for all users to use 100GB.)


Login

Only accessible within UTokyo campus network (including ECCS terminals and UTokyo Wi-Fi)

It is also possible to access from off-campus via UTokyo VPN.

Software for SSH2 protocol is required. 


On ECCS terminal

In Mac OS environment of ECCS terminal, login with "ssh" command is available. In Remote Access Environment (Splashtop) of ECCS, it is available, too.


In "Terminal"

% ssh csgs2.e.u-tokyo.ac.jp -l username

or

% ssh username@csgs2.e.u-tokyo.ac.jp


On X Window System, after starting XQuartz

% ssh csgs2.e.u-tokyo.ac.jp -l username -Y

or

% ssh usename@csgs2.e.u-tokyo.ac.jp -Y


On UTokyo Wi-Fi or via UTokyo VPN

Software for SSH2 protocol is required to access csgs2 in Windows PC connected to UTokyo Wi-Fi or UTokyo VPN.

Windows 10 1803 and later come standard with "ssh" command. 

At command prompt etc, please enter the following.

% ssh usename@csgs2.e.u-tokyo.ac.jp

In addition, for example, Tera Term that supports SSH2 protocol and UTF-8 is also available. 

After installation, please enter "csgs2.e.u-tokyo.ac.jp" in the "Host:" field of the connection destination. 


File transfer

"Scp" using SSH2 protocol  is available for file transfer. Only accessible within UTokyo campus network (including ECCS terminals, UTokyo Wi-Fi and UTokyo VPN), as with login.

In Mac OS environment of ECCS terminal, "scp" & "sftp" commands and "Cyberduck" application are available.

In Windows PC connected to UTokyo Wi-Fi or UTokyo VPN, for example, WinSCP is available.
