System Operation and Maintenance Measures on The University of Tokyo Activity Restrictions Index for Preventing the Spread of Coronavirus Disease 2019.

In response to the Japanese government’s move on April 6 to declare a state of emergency and the emergency measures taken by Tokyo Metropolitan Government, the University of Tokyo will impose maximum restrictions on campus activities to contain the spread of COVID-19.

Specifically, based on “The University of Tokyo Activity Restrictions Index for Preventing the Spread of Coronavirus Disease 2019,” released on April 3, the university is raising its level to ***3*** as of April 8 (“maximum restrictions”).

All the faculties and staff of ITC/U.Tokyo are teleworking now according to the BCP (Business Continuity Plan). This is also applied to engineers of companies who are working for operating our supercomputer systems. Only short on-site work less than 4-hours is allowed for keeping services as JHPCN (Joint Usage/Research Center for Interdisciplinary Large-scale Information Infrastructure). Although all the faculties, staffs and engineers are working hard for continuing operations, reduction of services (e.g. some computing nodes failed) may occur. We are very sorry for any inconvenience, and would like to thank you for your understanding this critical situation.

If the level might be raised to ***4***, our activities will be further restricted. Please make sure to backup your important files.

[Updated: Nov. 20, 2020]
From July 13th, the Activity Restrictions Index has been lowered to level 0.5(Minimum restrictions). However, ICT/U. Tokyo will continue to operate its activities at level 1(Partial restrictions) or level 2(Severe restrictions).

From July 13th, the Activity Restrictions Index has been lowered to level 0.5(Minimum restrictions). However, since Dec. 1, 2020, ICT/U. Tokyo has been operating its activities at level 2(Severe restrictions).
[Updated: Jan. 12, 2021]
The University of Tokyo raised the Activity Restrictions Index to level 1(Partial restrictions) on Jan. 11. ICT/U. Tokyo has been operating its activities at level 2(Severe restrictions) since Dec. 1 and will continue keeping level 2(Severe restrictions).
[Updated: Mar. 25, 2021]
The University of Tokyo lowered the Activity Restrictions Index to level 0.5(Minimum restrictions) on Mar. 22. However, ICT/U. Tokyo has been operating its activities at level 2(Severe restrictions) since Dec. 1 and will continue keeping level 2(Severe restrictions).
[Updated: Apr. 28, 2021]
The University of Tokyo raised the Activity Restrictions Index to level Pre-1(Minimum restrictions) on Apr. 26. However, ICT/U. Tokyo has been operating its activities at level 2(Severe restrictions) since Dec. 1 and will continue keeping level 2(Severe restrictions).
   
[Updated: June 22, 2021]
The University of Tokyo lowered the Activity Restrictions Index to level A(equivalent to the previous Level 0.5) on June 21. However, ICT/U. Tokyo has been operating its activities at level 2(equivalent to the present Level C) since Dec. 1 and will continue keeping level C(equivalent to the previous Level 2).
In addition, there is a possibility that the level might be raised again in the future. Again, although all the faculties, staff members and engineers are working hard for continuing operations, reduction of services (e.g. decreasing the number of some computing nodes) may occur. We are very sorry for any inconvenience, and would like to thank you for your understanding this critical situation.
Please refer to the following page for the information of university response to the COVID-19.

  • Ref. University Response to the Coronavirus Disease 2019
  • Special Notes of each operating supercomputer system.

    • Regarding the Oakforest-PACS and Reedbush-H/L: When the activity restrictions becomes level4, Fast file cache (IME) service will be (also) stopped. If you are currently using IME, please prepare for it.

    We are very sorry again for your inconvenience, and thank you very much for your patience.
