The Linux Kernel on the CLAIX18 compute nodes is being upgraded to kernel version 4.18.0-477.21.1. To maximise the availability of the compute cluster, the mandatory reboot of the nodes is scheduled as a reboot job, thus allowing all already submitted and running jobs for completion before the upgrade takes place.<\/p>\n

Please note that the reboot is prioritised over other jobs, and some nodes may be temporarily unavailable after the reboot.<\/p>\n
