Introduction to high-performance computing

This video was recorded during the 2021 HPC training sessions organised by the Consortium des Equipments de Calcul Intensif in collaboration with the CISM, the supercomputing centre of UCLouvain. More information here: http://www.ceci-hpc.be/training.html. The topic explains what HPC is and the basic concept that you need to know. It also gives a small introduction to our full port-folio of our formation with explaining quickly the key concept giving you the basis to work on HPC cluster.
