Duration

4 hours

Requirements

Each user shoud have PLGrid account, active affliation and access to Prometheus cluster. Accounts could be obtained in Portal PLGrid and access to Prometheus cluster in PLGrid Apps Catalogue. If somebody does not have active affliation please contact 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 of HPC resources at ACC Cyfronet AGH is Introduction to scientific High Performance Computing.

Venue

Training is going to be conducted via Zoom through link provided for registered participants.
