At the workshop, you will familiarize yourself with the structure and software of computing clusters and launch our first jobs. You will learn to distinguish between login nodes, head nodes, compute nodes, and data nodes. Together, we will explore the role of the operating system, Slurm middleware, environmental modules, containers, and user applications. We will connect to the login nodes, transfer files to and from the supercomputer, launch jobs, and monitor their execution.


The workshop will be conducted in two parts. First, you will familiarize yourself with the hardware and software. Then we will put the supercomputer to work by processing video files.

Target Audience

The workshop is intended for researchers, engineers, students, and others who have realized that they need more computing resources than regular computers can provide.

Acquired Knowledge

Upon completing the workshop, you will:

  • understand how the supercomputer works;
  • be familiar with the main components of a computing cluster and their functions;
  • know the Slurm middleware;
  • understand environmental modules and containers;
  • know how to work with files and execute jobs;
  • be able to prepare execution scripts;
  • be proficient in video processing.
