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.

Agenda

• 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 
• 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

Duration

5 hours

Requirements

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.

Venue

Training will be conducted at ACC Cyfronet AGH at Nawojki 11 in Krakow in room 303 on the 3rd floor.

Language

English/Polish - dependent on the participants.
