bwUniCluster 2.0+GFB-HPC
On March 17, 2020, the SCC commissioned the new parallel computing system "bwUniCluster 2.0+GFB-HPC" (also known as bwUniCluster 2.0) as a state service as part of the Baden-Württemberg Implementation Concept for High-Performance Computing (bwHPC). This system replaced its predecessor, "bwUniCluster," and incorporated the extension acquired in November 2016.

The modern, advanced HPC system consists of more than 840 SMP nodes with 64-bit Xeon processors from Intel. It provides the universities of the state of Baden-Württemberg with basic computing power and can be used free of charge by the staff of all universities in Baden-Württemberg.
Each state university regulates the access authorization to this system for its employees itself. Users who currently have access to bwUniCluster 1 will automatically also have access to bwUniCluster 2.0+GFB-HPC. There is no need to apply for new entitlements or re-register. Further details regarding registration and access to this national service are available at wiki.bwhpc.de/e/bwUniCluster_2.0.
The bwUniCluster 2.0 is a massive parallel computer with a total of 848 nodes. Across the entire system, a theoretical peak performance of approx. 1.4 PetaFLOPS and a total memory expansion of approx. 119 TB result.
The base operating system on each node is a Red Hat Enterprise Linux (RHEL) 7.x. The management software for the cluster is KITE, a software environment developed at SCC for the operation of heterogeneous computing clusters.
As a global file system, the scalable, parallel Lustre file system is connected via a separate InfiniBand network. By using multiple Lustre Object Storage Target (OST) servers and Meta Data Servers (MDS), both high scalability and redundancy in the event of failure of individual servers are achieved. The new parallel file system procured together with the bwUniCluster 2.0+GFB-HPC has a total capacity of about 5 PetaByte with a total throughput of about 72 Gigabyte per second.
