Project Mentor

A mentor is assigned to each scientific project, that is currently being conducted on the supercomputers at JSC. The mentor acts as a permanent point of contact between the project and JSC. The mentor is available for requests concerning further support and training offers by JSC or helps to arrange in-depth code analyses. The individual mentor of each project can be found within the project overview in JUDOOR.

More information concerning the project mentor is available here.

Cross-sectional teams

There are three special task forces taking care of code scalability:

The cross-sectional team "Mathematical Methods and Algorithms" provides know-how in numerical kernels and assists users in using these algorithms: Mathematical Methods and Algorithms

The cross-sectional team "Performance Analysis" offers several tools to analyze parallel programs and supports in the usage of these tools : Performance Analysis

The cross-sectional team "Application Optimization" offers special support for users on program optimization: Application Optimization

The cross-sectional team "Visualization" gives support for the visualization of scientific data and for multimedia productions: Visualization

The cross-sectional team "Deep Learning" provides support for users with the application of deep learning methods: Deep Learning

All teams are strongly collaborating with the  simulation laboratories. The Simulation Laboratories also offer a dedicated call for preparatory access.

Distributed Compute and Data Services Support

The Juelich Distributed/Data Services Support Team (DS-Support) supports the users of distributed computing and data services, such as
