The server 'Carpet' is the name of the SHARCNET hosted instance of Openstack. This page describes how to get access to Carpet with a short description of how to launch an instance. For more information see Getting started with Cloud Computing.
The SHARCNET cloud is located on https://cloud.sharcnet.ca/dashboard , To login to the cloud, you will need to request access by submitting a ticket to sharcnet. After access is granted, you will be able to login using your Compute Canada (not SHARCNET) username and password.
The first thing you need to do is to create a keypair. The key pair will allow you to login to the instances you create in the cloud. To do so follow the following guidelines
Under the “Compute” tab, press on “Access & Security” tab in the left hand side.
(1) Press “Key Pairs” tab
(2) Create “Create Key Pair” in the upper right corner
(3) Choose a name for the keypair
The cloud will automatically download a file to your desktop. The file’s name will be “Name you chose for the keypair”.pem. This .pem file is the way you will access your machines

Follow the following steps to achieve that:
(1)Under the “Compute” tab”, press on “Access & Security” tab in the left hand side.
