This downtime is needed for updating the Lustre WORK storage. These updates include the final patch for the Lustre metadata bug , which we have experienced from May until July and we have received a preliminary patch. Additionally this updates includes updates for a few smaller bugs. Additionally we will use this downtime to install necessary software patches on all core servers and compute nodes as well as preparing the network infrastructure for the installation of our upcoming GPU partition with AMD Epyc nodes with 4 Nvidia A100 GPUs at the new GWDG main data center RZGÖ.
