Architecture of DACHS
The Datenanalyse Cluster der Hochschulen (DACHS) is a parallel computer with distributed memory connected over Infiniband and Ethernet. The compute nodes contain at least dual AMD processors, at least 384GB of local memory, 2 TB local NVMe-based disc storage and accelerators as shown in the table below. With BeeGFS a fast and scalable filesystem is provided via Infiniband to all login and compute nodes
The Operating System is Rocky-Linux 9.4 (which is based on RHEL). The setup is kept in-line (with regard to Software, Setup and general usage) is mostly equivalent to bwHPC and bwUniCluster in particular.
