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.

This workshop provides an introduction to basic command-line operations and guidelines for working efficiently on Gadi, the high-performance computing (HPC) machine at the National Computational Infrastructure (NCI).

Prerequisites

Access to a shell that supports SSH.
NCI account

Attendees are strongly encouraged to attend the Seminar: Getting Started with Gadi before the course.
