Introduction to High Performance Computing for Supercomputing Wales: Introduction to Supercomputing Wales

Introduction to Supercomputing Wales

This lesson introduces using the Supercomputing Wales HPC system.


Some basic experience of the Unix command line is expected. The material covered in the Software Carpentry Introduction to the Unix Shell is more than enough to cover this.
