[Matter-users] Kappa/Matter service stop 2014-08-26 09:00-13:00

[Mats Kronberg]

Dear Kappa and Matter users,

Due to required maintenance to the electrical system in one of our
computer rooms, we will have to shut down all Kappa and Matter compute
nodes for a few hours on August 26th.

Start of downtime: 2014-08-26 09:00 CEST
Estimated end of downtime: 2014-08-26 13:00 CEST

The login nodes will not be affected, so you can still access your
files and manage queued jobs.

Queued jobs that have requested enough time that they cannot finish
before the downtime will not be started. E.g 7 day jobs cannot start
if there are less than 7 days remaining before the stop.

If you need to run jobs in the week before the downtime, you might
need to shorten your jobs.

Jobs that are in the queue before the downtime will remain in the
queue, and will be started normally after the downtime.

Hint to low-priority projects: short jobs will find it easier than
usual to run in the days immediately before downtime, as they don't
have to compete with longer jobs.

Triolith will not be affected.
