Interactive supercomputing with JupyterLab

With JupyterLab, KIT researchers can now very easily interact with the SCC's high-performance computers directly from any workstation using a web browser. This also opens up new possibilities for courses.

The project Jupyter [1] started some years ago. It evolved into a project that today represents a complete open source ecosystem for programming, data exploration and code execution. Most importantly, Jupyter offers a new way of supercomputing that allows interactive work with kernels, text editors and data visualization on HPC systems.

Since the end of October, SCC offers Jupyter as a service [2]. In addition to the classic access via SSH, interactive access via web browser to all HPC systems of the SCC is now also possible. For the Tier-3 system, bwUniCluster2.0 + GFB-HPC, the new AI/ML-GPUs of the HAICORE partition and the Tier-2 inventory system ForHLR II, dedicated queues are reserved for Jupyter.

This minimizes waiting times and allows especially new users of our HPC systems a low entry threshold.

To use Jupyter on the HPC resources of the SCC the respective access requirements apply. Registration of access via is required. The Jupyter service is only available within the KIT network. If the service is to be used from outside, a VPN connection to the KIT network must first be established.
