On the weekend on 15/16th July there will be essential maintenance being carried out on the 5 West data-centre. For this work to be carried out, Balena will need to powered down for that weekend. Following on from this planned service interruption we are going to keep Balena offline for the following week to carry out our own essential maintenance on Balena, see details below.

ClusterVision and the HPC Team will be working on the system during this period.

  • All jobs will need to be dequeued before the Balena shutdown - we will put in a reservation to make sure there are no jobs in running state when the system in shutdown.
