Hochleistungsrechnen (HPC)

Hinweis: Aufgrund der Zielgruppe sind die Dokumentationen zu den HPC-Systemen in Englisch. Allgemeine Informationen zu den Dienstleistungen der HPC-Gruppe am RRZE finden sie auf den RRZE-Webseiten.

The HPC group of RRZE operates a number of clusters and related systems mainly for scientists at FAU.

Getting started

If you are new to HPC and want to know about the different clusters, how to log in, transfer files and run jobs, please refer to our Getting Started Guide.

HPC Clusters

The following table lists the available clusters and their key properties. To get further information about each cluster, click on the cluster name in the first column.

description
Meggie 728 massively parallel Yes No This is the RRZEs newest cluster, intended for highly parallel jobs. Access to this cluster is restricted.
Emmy 560 massively parallel Yes No This is the current main cluster for parallel jobs.
LiMa The system has been retired in December 2018.
Woody 286 serial throughput No Yes Cluster with fast single-socket CPUs for serial throughput workloads.
TinyEth 20 throughput No Yes Cluster for throughput workloads.
TinyGPU 37 GPGPU No Yes, some
with SSDs
The nodes in this cluster are equipped with different types and generations of NVIDIA GPUs. Access restrictions / throttling policies may apply.
TinyFat 25 large memory requirements No Yes, some
with SSDs
This cluster is for applications that require large amounts of memory. Each node has between 128 and 512 gigabytes of memory. Access restrictions may apply.

If you’re unsure about which systems to use, feel free to contact the HPC group.

Other HPC systems at RRZE

Dialog server

This machine can be used as an access portal to reach the rest of the HPC systems from outside the university network. This is necessary, because most of our HPC systems are in private IP address ranges that can only be reached directly from inside the network of the FAU

HPC Testcluster

The HPC Testcluster consists of a diversity of systems (countless X86 variants, ARM, NEC Aurora/Tsubasa, …) intended for benchmarking and software testing. Contact the HPC group for details. Access to certain machines may be restricted owing to NDA agreements.

HPC software environment

The software environment available on RRZE’s HPC systems has been made as uniformly as possible, in order to allow users to change between clusters without having to start from scratch. Documentation for this environment can be found under HPC environment.

Access to external (national) HPC systems

LRZ systems

Users that require huge amounts of computing power can also apply to use the HPC systems of the „Leibniz-Rechenzentrum der Bayerischen Akademie der Wissenschaften“ in Garching near Munich.

National systems at HLRS and JSC

Access to the national supercomputers at HLRS (High Performance Computing Center Stuttgart) or JSC (Jülich Supercomputing Centre) requires a scientific proposal similar to SuperMUC at LRZ. Depending on the size of the project, the proposals have to be submitted locally at HLRS / JSC or through large-scale calls of GCS (Gauss Center for Supercomputing).
