Introduction to Supercomputing at JSC - Theory & Practice (training course, online)

(Course no. 8920212 in the training programme 2021 of Forschungszentrum Jülich)

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

Through the John von Neumann Institute for Computing, Research Centre Jülich provides high-performance computing resources to scientific user groups from throughout Germany and Europe and to its industry partners. The aim of this course is to give new users of the supercomputers an introduction to the systems, such that they can make efficient use of their allocated resources.

The course will start with the upload of credentials to the systems before logging in for the first time. We then go on to explain how to navigate the systems and get the user's data and programs in place. By the end, participants will be running their first small computations on the supercomputers.

Theoretical lectures will be held in the afternoon from Monday to Thursday. To turn theory into practice tutorials will be offered in the mornings from Tuesday to Thursday, which cover some of the material from the preceding afternoon.

In May 2021, these two parts of the course were offered as two separate courses with separate registration forms. They have now been combined and there is only one registration form which lets you select the parts of the course you wish to attend. We strongly suggest that registrants attend both parts.

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
  • Visualization
