Introduction
This guide is designed to be a reference for users of the high-performance computing (HPC) facility: Cirrus. It provides all the information needed to access the system, transfer data, manage your resources (disk and compute time), submit jobs, compile programs and manage your environment.
Acknowledging Cirrus
You should use the following phrase to acknowledge Cirrus in all research outputs that have used the facility:
This work used the Cirrus UK National Tier-2 HPC Service at EPCC (http://www.cirrus.ac.uk) funded by the University of Edinburgh and EPSRC (EP/P020267/1)
You should also tag outputs with the keyword Cirrus whenever possible.
Hardware
Details of the Cirrus hardware are available on the Cirrus website:
Useful terminology
This is a list of terminology used throughout this guide and its meaning.
CPUh
Cirrus CPU time is measured in CPUh. Each job you run on the service
consumes CPUhs from your budget. You can find out more about CPUhs and
how to track your usage in the resource management section
GPUh
Cirrus GPU time is measured in GPUh. Each job you run on the GPU nodes
consumes GPUhs from your budget, and requires positive CPUh, even though
these will not be consumed. You can find out more about GPUhs and how to
track your usage in the resource management section
