The bwHPC symposium focuses on the presentation of scientific computing projects as well as on the progress and the success stories of the bwHPC initiative. The event offers a unique opportunity to engage in an active dialog between scientists using high performance compute resources, operators of bwHPC sites, and the bwHPC-C5 support centers.

Call for contributions is now open (

  • We invite all participants to present their bwHPC-related research as a poster and/or a (short) paper (1000-6000 words or 4-20 pages in LaTeX). Selected contributions will be published in the conference proceedings.
  • Talks will be selected by the program committee; a paper contribution to the proceedings is encouraged but not required.
  • Please submit in any case a short summary and optionally an abstract in "Call for contributions".
  • Proceedings contributions should use the following LaTeX template or the following overleaf link for online editing.
  • There is no template for Microsoft Word or Libreoffice contributions, please  if you would like to contribute in this format.


The proceedings of the bwHPC symposium 2018 will be published online via the library of the University of Tübingen. The contributions will be peer reviewed. A minimum length of 1000 words (about 4 pages in LaTeX template) is required for a contribution to be eligible for inclusion. Contributions to proceedings are limited to 20 pages (using the LaTeX template) or 6000 words respectively. Preprint versions of the proceedings are planned to be available at the time the bwHPC symposium takes place.

ZKI AK Supercomputing

The ZKI AK Supercomputing Meeting will be held directly after the bwHPC symposium at the same venue on September 25/26. Attendees of the bwHPC symposium are welcome to join the Supercomputing Meeting and vice versa. We kindly ask you to register for both events separately.

Registration link for the ZKI AK Supercomputing Meeting will follow.

Since 2013, the Centre de Calcul de l'Universite de Strasbourg organises an annual seminar in collaboration with the Lycée Marguerite Yourcenar in Erstein near Strasbourg. The students are given scientific lectures to get an insight into potential fields for their future studies and work.

In 2018, using Neurocampus and Eucor as inter-regional frameworks for cooperation in the upper rhine valley, the event takes place at the university of Strasbourg. 


09:00 - 09:10 : Opening (R. David, V. Lucas, B. Wiebelt)

09:10 - 09:40 : Didier Rognan (University of Strasbourg) - Medicine 

09:40 - 10:15 : 2 talks of the pupils from the Lycée Marguerite Yourcenar 

10:15 - 10:30 : Break

10:30 - 11:00 : Christoph Heidecker (KIT, Karlsruhe) - Particle Physics

11:00 - 11:30 : Stefan Rotter (Bernstein Center Freiburg) - Computer Simulations in Brain Research 


NEMO Maintenance on 13.03.2018

The maintenance is prompted by a function test of the power system of the Rechenzentrum. The downtime will be used to apply all pending software and hardware upgrades to NEMO.

Nemo will be down for maintenance on 13.03.2018. We will make good use of this externally triggered downtime by applying all pending software upgrades to NEMO. Job scheduling will be suspended during the maintenance. Login and access to your files will not be possible during the maintenance.

You can submit jobs until the downtime starts (13.03.2018, 06:00 AM). Please note that jobs projected to finish after the downtime starts will be blocked. Your jobs should run after the downtime is complete.

Introduction to Software Deployment in Virtualized Research Environments

On 04.12.2017 the Rechenzentrum of the University of Freiburg is hosting an introductory workshop on creation, usage, maintenance and sharing of Virtual Research Environments (VRE). The focus is on Neuroscience-related software (e.g. NEST, Neuron, Tensorflow, Python) but the methods and examples presented can be applied to other scientific fields as well.
When Dec 04, 2017
from 10:00 AM to 05:00 PM

Target audience: Scientists (students, PhD students, Postdocs) who need well-defined software environments on the bwForCluster NEMO or in the bwCloud that they can control themselves.

Principal goals of the workshop: 

  • Overall: Learn how to create, use and maintain, and share virtual research environments (VRE) on NEMO or bwCloud.
    • Clarify distinction between the ability to *distribute/reconstruct* a VRE (ViCE) versus the ability to reference/archive/re-execute of VRE (CiTAR)
    • Usage of "conda" for software package management in user space (i.e. no admin required)
    • Create and run singularity containers on HPC for maximum independence from given HPC node operating system and software environment
    • Handle specific or conflicting Python requirements in separate VREs
    • Share VRE images or VRE recipes between users


RSVP not required, but appreciated for planning purposes. If you are interested in attending or have any questions, please send an email to



ViCE Workshop on Provisioning of Virtual Research Environments and Data Management

The ViCE project team organized together with the CiTAR and the de.NBI project a two day workshop and hackathon on Virtual Research Environments and Data Management at the computer center of the university. One of the workshop goals was to produce an overview over (competing) strategies, approaches and tools for provisioning Virtualized Research Environments for different disciplinary use cases of the project partners.

Add event to calendar vCal

The first day of the workshop started with presentations and live demos by Jonathan Bauer on "Current developements in bwLehrpool" and the convergence of VM building and PXE booting in bwLehrpool context as well as the provisioning of the major container technologies Docker and Singularity (Beta) on that platform. Björn Grüning of Prof. Backofen's group in Freiburg and associated to the de.NBI project (German Network for Bioinformatics Infrastructure) demonstrated practical computational reproducibility in the life sciences. The session was followed by Oleg Stobbe from the CiTAR projecton current developments in VRE frameworks. The first session got closed by Christopher Hauser from Ulm University by a presentation of ViCE Registry project.

Participants of ViCE/de.NBI/CiTAR Workshop on Virtualized Research Environments - Provisioning and Data Management

The afternoon session was dedicated to a hacking sessions on ViCE Registry, ways of VRE building (Container/VM) and the access to research data (Research Data Management). The second day clarified the distinction between provisioning of VRE (ViCE) and re-usability of VRE (CiTAR) as well as defined some (lightweight) guidelines for the creation of VRE and VRE workflows. Several existing usecases (HEP, computational chemistry, bioinformatics, bioconda for HPC) in different disciplines got discussed and evaluated for further uptake. Additionally, external dependencies (services, hardware, data sources and sinks, ...) of VREs were summarized. The workshop produced a good overview on the current state of developments in that field.
