(2025/09/05) The operation of csgs2 server was discontinued by August 31, 2025 and migrated to a new server (csgs3). To use the csgs3 server, please make sure to complete the key registration procedure in advance.
As a general rule, csgs3 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.
It is available to students of Graduate School of Economics.
Please register the course “Graduate School of Economics, using the Computing Server for graduate students” from UTOL.
Please use the course assignment “ssh 公開鍵/public key(id_ed25519.pub)提出/upload” to upload your public key.
(After the new server is up and running) Account setup will be done manually by the staff. Once your account is ready, you will be notified via your ECCS Cloud eMail address, so please wait a few days.

As a general rule, csgs3 is restarted once a month (early morning on the first day of every month) for system maintenance.
In addition, csgs3 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.
Please back up your calculated data, program data, etc. on your own responsibility.
(The csgs3 manager is not responsible for any data loss due to an accident or user's incorrect operation.)
The home directory of csgs3 is completely separate from that of ECCS.
To prevent accidents, the disk quota (up to about 100GB) is set for each home directory. Please contact the csgs3 manager (Email: csgs-info [at] e.u-tokyo.ac.jp) if you need more quota to calculate. However, in some cases it may not be possible to respond to your request. Thank you for your understanding.
In addition, the csgs3 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.)
Please enable your ECCS Cloud Email (**@g.ecc.u-tokyo.ac.jp) so that you can read it. If the csgs3 manager needs to contact each user, user's ECCS Cloud Email is used.
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.
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 csgs3.e.u-tokyo.ac.jp -l xxxxxxxxxx
or
% ssh xxxxxxxxxx@csgs3.e.u-tokyo.ac.jp
*xxxxxxxxxx is your common ID(10 digits).
On X Window System, after starting XQuartz
% ssh csgs3.e.u-tokyo.ac.jp -l xxxxxxxxxx -Y
or
% ssh xxxxxxxxxx@csgs3.e.u-tokyo.ac.jp -Y
Software for SSH2 protocol is required to access csgs3 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 xxxxxxxxxx@csgs3.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 "csgs3.e.u-tokyo.ac.jp" in the "Host:" field of the connection destination.
"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.
