[Sigma-users] Sigma unavailable next Wednesday 13:00-17:00 CEST

[Mats Kronberg]

Dear Sigma users,

Sigma will be unavailable next Wednesday (April 28th) from 13:00 to
17:00 CEST.

During this time we will upgrade the Slurm job scheduler. This should
among other things solve a problem where graphical applications would
sometimes not work in "interactive" sessions.

Queued jobs that cannot be completed before 13:00 will not be started
until after cluster is back online. All logged-in users will be logged
out at 13:00. Queued jobs will remain in the queue and be started
normally when the cluster is back online. During the downtime you will
not be able to access your data on /home and /proj.

Tetralith is not affected.

Best Regards,
