null Scheduled service break on Mahti: September 7 8:00 to September 8 17:00 (extended to September 9)

Service break extended to September 9 forenoon.

There will be a service break on Mahti from Tuesday September 7 at 8:00 to September 8 at 17:00. During the service break there will be no access to the system including login nodes and storage system.

In the service break a number of important maintenance operations will be carried out, improving reliability and functionality of the system. In this service break also the storage system will be upgraded. The long duration fo the break is an unfortunate consequence of the complexity of the upgrade process.

Applications you have installed yourself will in almost all cases still function after the break. If you encounter any issues, then we recommend that you as a first step recompile the application.

The updated slurm will change how "srun prog &" functions. This change occured in Puhti in May, see https://docs.csc.fi/support/wn/comp-new/ for more information.
