Description

This lesson provides an introduction to using Cirrus for users who:

  • have already used other HPC systems; and
  • want to use pre-installed simulation/modelling packages rather than compiling their own.

The lesson aims to answer the following questions:

  • What hardware is available on Cirrus?
    • What does it consist of (login nodes, compute nodes, file systems, backup)?
    • How does this impact me as a user?
  • How can I access Cirrus interactively and transfer data?
  • What does the Cirrus software environment look like and how do I access software?
  • How do I write job submission scripts and submit them to the Cirrus scheduler?
  • How can I be a good Cirrus citizen?
  • How can I check what resources I am using and look at historical usage?
  • What are the next steps for me using Cirrus and how can I get more help?

{% comment %} SPECIAL REQUIREMENTS

Modify the block below if there are any special requirements. {% endcomment %}

Requirements: Participants must have a working laptop or desktop computer with a Mac, Linux, or Windows operating system (not a tablet, Chromebook, etc.) that they have administrative privileges on. They should have access to a terminal (Mac and Linux users should have a terminal installed by default; Windows users should get either MobaXterm. They are also required to abide by the Cirrus Terms and Conditions of Access.

{% comment %} ACCESSIBILITY

Modify the block below if there are any barriers to accessibility or special instructions. {% endcomment %}

Accessibility: Materials will be provided in advance of the lesson and large-print handouts are available if needed by notifying the organizers in advance. If we can help making learning easier for you (e.g. sign-language interpreters, lactation facilities) please get in touch (using contact details below) and we will attempt to provide them.

GPU queue reservations: The organisers of this course have reserved GPU nodes specifically for this course. To run on the GPU reservation, you will need to use the following Slurm variables:

#!/bin/bash
#SBATCH --job-name=my_mpi_job
#SBATCH --time=0:10:0
#SBATCH --account=ic084
#SBATCH --partition=gpu
#SBATCH --qos=reservation
#SBATCH --reservation=<reservation_id>

# Instructions to be run by Slurm

{: .language-bash}

You will need to replace <reservation_id> with the appropriate ID:

Reservation date and time Reservation ID
13:30-16:00 on 8th July ic084_1263984
09:00-19:00 on 9th July ic084_1263955
09:00-19:00 on 10th July ic084_1264032
08:30-19:00 on 11th July ic084_1263958
09:00-16:00 on 12th July ic084_1263951

{% comment %} CONTACT EMAIL ADDRESS

Display the contact email address set in the configuration file. {% endcomment %}

Contact: Please email {% if page.email %} {% for email in page.email %} {% if forloop.last and page.email.size > 1 %} or {% else %} {% unless forloop.first %} , {% endunless %} {% endif %} {{email}} {% endfor %} {% else %} to-be-announced {% endif %} for more information.

Prerequisites

You should have used remote HPC facilities before. In particular, you should be happy with connecting using SSH, know what a batch scheduling system is and be familiar with using the Linux command line. You should also be happy editing plain text files in a remote terminal (or, alternatively, editing them on your local system and copying them to the remote HPC system using scp). {: .prereq}
