This course will take place as an online event and is exclusively targeted for users of the Jülich supercomputers. The link to the online platform will be provided to the accepted registrants only.


Disclaimer: This course offers the opportunity to attend lectures selectively, based on individual needs and knowledge levels. Participants are not required to attend all sessions as some may cover advanced or basic material. While flexibility is offered, it is important to assess personal needs and choose sessions accordingly, as attending lectures out of order may result in knowledge gaps.

Research Centre Jülich provides cutting-edge high-performance computing resources to scientific groups and industry partners across Germany and Europe via the John von Neumann Institute for Computing. To help new users of JSC's supercomputers efficiently leverage their allocated resources, we offer an introductory course that covers system basics and best practices.

The course includes theoretical lectures held every afternoon from Monday to Thursday, and practical tutorials offered in the mornings from Tuesday to Thursday. The tutorials are based on the previous afternoon's lectures and allow articipants to put theory into practice. We cover a wide range of topics, starting from basic log-in procedures to intermediate-level techniques. Participants are free to choose the lectures that best match their needs and interests.

Topics covered include:

  • User account management with the JuDoor portal
  • System access via SSH, Jupyter, and UNICORE
  • System configuration for JURECA and JUWELS
  • File systems, I/O, and data management
  • Software modules (compilers, MPI, math libraries, applications, debuggers, tools)
  • Building software from source
  • Submitting jobs via the resource manager
  • Using GPUs
  • Performance tuning
  • Deep Learning
  • Visualization
