The University of Bonn runs two small HPC systems ("bonna" and "bender") for small-scale computing projects. "bonna" is an MPP cluster, "bender" is a GPU cluster. A third, much bigger system "marvin" is currently being purchased, it will consist of both MPP and GPU partitions, being at least an order of magnitude bigger than both "bonna" and "bender" combined.

The cluster "bonna" was purchased and installed in 2019 to meet small-scale needs for HPC resources. "bonna" is purely a MPP cluster with 2240 cores. It is currently maintained by Fraunhofer SCAI. 

For the teaching and small research projects (e.g. a bachelor or master thesis) the University of Bonn offers the small GPU cluster "bender", consisting of 16 Nvidia A40 GPUs. "bender" is currently open to all members of the University of Bonn. Application form can be found in the system description.

A much bigger HPC-system, both with large MPP-, as well as twi extensive GPU-partitions, has just been purchased from Megware. Contrary to expected, we expect "Marvin" to be available for modellers by summer 2023 already, hoping that the estimations for delivery times remain stable.

In addition to productive HPC ressources, the HRZ-HPC-team works on smaller "fun" projects for teaching. At this point of time, this is just one project, a tiny HPC cluster that students/trainees build themselves, consisting of Raspberry Pis. More projects are planned for the future.

Tiny cluster continously re-assembled within the context of workshops, to demonstrate the basics of HPC cluster architecture.
