Efficient usage of HPC systems in scientific computing



Klemens Noga (ACC Cyfronet AGH), Maciej Czuchry (ACC Cyfronet AGH)

The "Efficient usage of HPC systems in scientific computing" course is aimed at users who want to expand their knowledge and skills in working with HPC systems available at ACC Cyfronet AGH.


  • HPC systems usage
    • login and data transfer
    • command line interface for remote access to servers
    • remote visualisation and remote desktops
  • Available computational and storage resources of Ares and Athena supercomputers
  • Scientific software environment management (Modules/Lmod)
    • compilation of users' software
    • usage of users' own modules
    • Python environments management 
    • HPC containers
  • Working with queuing systems
    • batch scripts
      • sequential, parallel and distributed computations
        • srun
        • OpenMP
        • MPI
        • hybrid OpenMP + MPI
      • jobs with GPGPUs
      • array jobs
    • interactive jobs
    • jobs' dependencies
    • additional nodes features
    • efficient usage of the SLURM queuing system
      • job monitoring
  • Documentation and user support
  • Ares and Athena as an integral part of PLGrid Infrastructure
  • EuroHPC (LUMI) - computational opportunities


5 hours


Each user should have a PLGrid account, active affiliation and access to the Ares cluster. Accounts and access to supercomputers could be obtained in Portal PLGrid. If somebody has no active affiliation, please get in touch with organisers at training@cyfronet.pl.

That is more advanced training for people familiar with basic usage of HPC resources. Basic training for people who want to start using HPC resources at ACC Cyfronet AGH is Introduction to Scientific High-Performance Computing.


Training will be conducted via Zoom through the link provided for registered participants.


English/Polish - dependent on the participants.
