Introduction to Gadi - UNSW
Event description
Gadi is Australia’s most powerful supercomputer, a highly parallel cluster comprising more than 180,000 processor cores on ten different types of compute nodes. Gadi accommodates various tasks, from running climate models to genome sequencing, from designing molecules to astrophysical modelling.
Introduction to Gadi is designed for new users, or users that want a refresher on the basics of Gadi.
