File transfer to/from the cluster ---------- There is a special node dedicated to data transfer with the cluster system. Whenever you transfer data with the cluster system, please use this node: transfer.cluster.uni-hannover.de Please note: Use the dedicated transfer node for file transfers, because processes that use more than 30 minutes of cpu time on the login machines will be aborted by the system. Since ssh/scp use encryption, you may eventually use enough cpu time to get the transfe…

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.

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,…

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
