→ Europe/Athens
Description

EuroCC@Greece announces the 22nd Course of HPC Training Series with the subject "HPC Fundamentals, Slurm, Open OnDemand & XDMoD".

Date: July 13th, 2026, at 12:00 EEST 

Location: Online via Zoom  

Presentation Language: Greek

Audience: This course is ideal for HPC Engineers and Academic Researchers.

Learning Objectives:

By the end of the seminar, participants will be able to:

  • Explain the role of High Performance Computing in AI, science, and engineering workloads.
  • Identify key HPC components, including nodes, CPUs, GPUs, memory, storage, and networking.
  • Understand parallel computing concepts such as tasks, threads, cores, speedup, and scaling.
  • Use basic Slurm concepts to request resources, submit jobs, and monitor workloads.
  • Access HPC resources through Open OnDemand for interactive sessions, file management, and job submission.
  • Recognize when to use CPUs, GPUs, OpenMP, MPI, or CUDA for different computational tasks.

Prerequisites: Basic programming knowledge (preferably in C, C++, or Fortran).
