null Service break on Mahti 25.9.2020 - 1.10.2020 (updated)

Update: The service break has been extended to October 1

There will be an extended service break on Mahti. It will start on Friday September 25 at 16:00, and at the latest end on Tuesday September 29 at 12:00. During the service break there will be no access to the system including login nodes and storage system.

During the service break a number of important maintenance operations will be carried out. 1)  System level software will be updated in the interconnect and on the compute nodes in order to make the system more stable. 2)  Minor changes will be introduced to the interconnect topology to optimize its performance. The long duration of the service break is a consequence of the large amount of changes we have chosen to implement. However, this will reduce the need for arranging additional service breaks in near future.
