Linux based parallel computer / High performance computer Fritz (Megware)

FAU’s Fritz cluster (system integrator: Megware) is a high-performance compute resource with high speed interconnect, i.e., a parallel computer. It is intended for multi-node parallel workloads. Fritz serves for both, FAU’s basic Tier3 resources as well as NHR’s project resources.

• 4 front end nodes with the same CPUs as the compute nodes but 512 GB of RAM, and 100 GbE connection to RRZE’s network backbone.
• 1 visualization node with the same CPUs as the compute nodes but 1024 GB of RAM, one Nvidia A16 GPU, 30 TB of local NVMe SSD storage, and 100 GbE connection to RRZE’s network backbone.
• 992 compute nodes with direct liquid cooling (DLC), each with two Intel Xeon Platinum 8360Y “Ice Lake” processors (36 cores per chip) running at a base frequency of 2.4 GHz and 54 MB Shared L3 cache per chip, 256 GB of DDR4-RAM.
• Lustre-based parallel filesystem with a capacity of about 3,5 PB and an aggregated parallel I/O bandwidth of > 20 GB/s.
• Blocking HDR100 Infiniband with up to 100 GBit/s bandwidth per link and direction. There are islands with 64 nodes (i.e. 4.608 cores). The blocking factor between islands is 1:4.
