Introduction using Komondor supercomputer

Friday 12 Dec 2025, 08:45 → 13:00 Europe/Budapest

The focus of the entry-level workshop will be on the DKF's supercomputer, Komondor. The aim of the workshop is to provide participants with the essential basics of using the new cluster in a short, hands-on event. During the event, we will jointly review the hardware and software environment of the machine, connectivity and data movement options, available compilers, and how to compile and run multi-threaded, multi-processing or GPU-based programs. 

Lecturer: Dr. László Környei  (Associate Professor Associate at the Széchenyi István University), HPC expert (DKF)

Language of the workshop: English

Venue: online/teams 

The event is recommended for those who would like to try out the new supercomputer with hands-on support and have user-level Linux command-line skills.

We will send to the participants a handout prior to the workshop with detailed information on how to register on the HPC portal and log in to Komondor. Please, do follow the instructions detailed in the handout as soon as possible, and log in to the system at least 24 hours prior to the seminar in order to be able to carry out the exercises yourself.

You are welcome to join the meeting at 8:45 for a final technical check.

Registration deadline: 11th December 2025
