Citing the compute cluster LUH´s compute cluster is partly funded by the DFG as Major Research Instrumentation (Forschungsgroßgerät). In fact, several parts of the compute cluster have been funded independently in the past. The most recent addition is the compute cluster partition Amo. When publishing research that has been significantly helped by using compute cluster, we would like to politely ask for a reference also containing to the DFG funding, which is not part of the funding guidelines,…

SLURM usage guide ---------- If you are completely new to scientific computing, read this: Please keep in mind that simply throwing a serial program without provisions for parallelization at the cluster will not make it run faster. In fact, it will often run SLOWER, since cpu cores on machines specialized in scientific computing usually run at lower clock frequencies than workstation cpus.

JupyterHub for teaching on LUIS cluster ---------- We provide an instance of the JupyterHub platform to support giving lectures in the LUH compute cluster environment. The JupyterHub server also runs the system NbGrader, which allows you to assign, distribute and (automatically) grade Jupyter notebooks. The JupyterHub platform is intended only for non-critical teaching activities that require LUIS cluster resources. If you want to use Jupyter notebooks for your own research, use the

Cluster introductory course All members of Leibniz Universität Hannover can join (free of charge) a basic introductory course for the LUIS compute cluster. During the course, you will learn about the capabilities of the system, how to set up batch jobs, work with software modules and various file systems as well as how to transfer files to and from the compute cluster. Preliminary experience in working with compute clusters is not required, but at least some familiarity with Linux and/or the co…

Section 1: What is ZFS? (The Modern Foundation) ZFS is a combined File System and Logical Volume Manager. In traditional Linux storage, you have a “sandwich” of different layers that do not talk to each other. ZFS removes these barriers by merging them into one intelligent software layer.
