Use Computers


General Use

CCS has received approval of “base of shared use and joint research” from the MEXT (Ministry of Education, Culture, Sports, Science and Technology, JAPAN).

Aiming to be the base of Interdisciplinary Computational Science, CCS carries out “Collaborative Interdisciplinary Program”. Contributing to the development of computational science, shared use of supercomputers under management of CCS is working. Shared supercomputers are “HA-PACS“, “COMA” and “Oakforest-PACS“.

 Resuming Operation of PACS-CS for Shared Use in the FY2011

On May 2, operation of PACS-CS resumed from discontinuing because of aftermath of the 2011 Tohoku earthquake and power-saving.

Accoring with this resumption, Collaborative Interdisciplinary Program of FY2011 in Center for Computational Sciences, University of Tsukuba started with 1 month dalay.
We appologize to Collaborative Interdisciplinary Program users for inconvenience.

Until the end of June, PACS-CS will operate 24 hours with 100% resources. In the Summer, PACS-CS is planned to peak-hour shutdown due to energy-saving. We are trying to cope with the power situation, and thank you for your understanding and cooperation.


PACS-CS File Access Service Resumed

From March 11, because of the Tohoku region Pacific Ocean earthquake, we apologize to PACS-CS users for the condition that remote access to the file system was not available.

Login(Host) and the File Access Service are now available.
It is expected to require some time to resume regular operation of PACS-CS.
