Dear Neolith, Kappa and Matter users, A reminder: On Wednesday April 6th (2011-04-06) all NSC systems will be shut down due to required maintenance on the power substation that supplies our computer rooms. We will also use this downtime to perform various upgrades and changes to our clusters that cannot be performed during normal operations. The downtime for Neolith, Kappa and Matter will start at 08:00 CEST. We have scheduled the whole day for this, but will of course try to keep the actual downtime as short as possible. Neolith, Kappa and Matter including the login nodes will be unavailable to users during the downtime. Queued jobs that has a long enough walltime that they cannot finish before the downtime will not be started. E.g 7 day jobs cannot start after 2011-03-30, 3 day jobs cannot start after 2011-04-03, etc. 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 then usual to run in the days immediately before downtime, as they don't have to compete with longer jobs. A special note for Neolith users: During the last few weeks the job queue has been shorter than normal, and last weekend it was completely empty (i.e some nodes were idle) for a while. If you have jobs that you have not run before due to low priority, now is a good time to do so.
