The data center where the Boqueron cluster is hosted will be undergoing some electrical maintenance from Saturday November 23 to Sunday November 24. The electrical work requires that we power down a significant portion of Boqueron’s nodes in order to lighten the load on the the data center’s circuits.
Because of this, we have decided to stop accepting new jobs on half of Boqueron’s nodes effective immediately. These “drained” nodes will be powered down on Friday morning. Any jobs currently running on these nodes will continue as usual, but, if they are still running by the time the nodes are powered down, they will unfortunately be killed.
We realize this information comes on a somewhat short notice, but we at the HPCf were only informed today that the date for the electrical work would be this weekend, so we had no way of alerting our users earlier. We apologize for any inconvenience this situation may cause for your work.
All the affected nodes will be powered on again on Monday November 25. The nodes affected by this maintenance are the following: node011 through node020, node031 through node040, node051 through node060, and node071 through node080.
As always, if you have any questions or comments, please send them to firstname.lastname@example.org.
