Maintenance Schedule
Planned Downtime
Every two months, the whole cluster will be reserved for necessary maintenance. The downtime window begins at 6:00am, and ends when we have finished any necessary work.
How it affects the scheduler
Because all nodes will be down, jobs cannot be running during the maintenance window. In order to prevent jobs from being interrupted before their time limit, any jobs that would overlap with the downtime window will have to wait until that window is over.
To run your job immediately, specify a shorter --time value that does not overlap with the maintenance reservation.
