HPC ACCESS

HPC resources - typically expressed in core-hours - are available not only to academia, but also to SMEs, industry and the public sector. Scientists can apply for HPC resources from public funding. Explanations are linked in this category. We will be happy to advise users outside the scientific sector on access options - simply contact us via the contact form.
 
As soon as the HPC resources are granted, the systems can be used. Depending on requirements and experience, this is done either classically via the command line using a secure connection via Secure Shell (ssh) or interactively, for example securely via JupyterLab. The login is typically done via a frontend, from which so-called jobs are sent, in which the work orders defined by the user are processed with the requested resources (computing nodes / cores, duration). Both the jobs and the entire project can be continuously monitored (job monitoring, user portal). Explanations and examples of technical HPC access are given below.

Software

No High Performance Computing, AI or Cloud Computing without software! Modern HPC systems differ significantly from consumer computers in terms of their architecture (e.g. type and number of computing cores, size of main memory), storage media and, above all, the usually complex network topology. Therefore, operating systems adapted to the HPC systems are used. Based on these, a broad software portfolio is made available to users. On the one hand, this includes basic software adapted to the HPC system, such as compilers or communication libraries for parallel computing, and on the other hand, HPC applications, such as simulation software and scientific libraries. The software offer is usually available to users via a modular system. Software components in the desired versions can be assembled and used in computing jobs. 

The offer includes open source packages and community applications as well as commercial software. Furthermore, users are free to install software packages or self-developed programmes in their private directory. On request, software can also be included in the portfolio or support provided for installation and configuration on the HPC system.

Explanations and examples of software are given below.

Datenmanagement

HPC projects typically generate large amounts of data. Storage systems with features that meet requirements ensure optimal performance when handling this data. For example, parallel file systems enable fast, parallel reading and writing of data during an HPC job, which can be moved to long-term archives for permanent backup. Explanations of the different storage systems and their use, as well as the possibilities of data transfer between different file systems are linked in this category.

Visualisation & Postprocessing

We support engineers and scientists, industrial users but also the public sector in the visual analysis of data typically generated by simulations on high-performance computers.
Different visualisation methods and technologies from our portfolio can be used for this purpose. For the visualisation of results, separate access to designated visualisation nodes is necessary.

Access is via Remote Desktop (via a web browser) or Client-Server (software required). Another option is via VNC viewer (software required) or the use of JupyterLab (web browser). Further information and documentation can be found here.
