Hydra system upgrade with brand new nodes

We are very pleased to announce the ready availability of 20 new nodes in Hydra with last-generation CPUs and a larger memory and cache per core than usual. Alongside the addition of these new nodes, we are also upgrading the operating system of rest of the cluster, which will require a planned reboot of the login nodes on Friday 26/4 at 06:00 (CEST) rendering the cluster inaccessible for a maximum of 15 minutes. Queued and running jobs will not be disrupted.
