Reminder: please don't forget that Neolith, Kappa and Matter will be unavailable next Tuesday! Also note that since it is now less than seven days until the service stop, 7-day jobs on Kappa and Matter will no longer start normally. On Neolith this will start happening on Saturday (3-day jobs). Until the service stop, only jobs shorter than the remaining time until the stop (2011-11-22 00:00 CET) can be started.

The main reason for this downtime is to expand the available space on the /nobackup/global file system, and to do some changes (for better performance) to the nobackup file system that require the whole system to be shut down. 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 00:00 CET (midnight between Monday and Tuesday). We have scheduled the whole day for this, but will of course try to keep the actual downtime as short as possible. Queued jobs that have such a long walltime 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. Kind regards, -- Mats Kronberg, NSC Support <<a href="mailto:support@nsc.liu.se">support@nsc.liu.se</a>> </blockquote></div>
