e. Summary & Cleanup

In the previous sections, you setup an HPC cluster with system monitoring and performance dashboards. You then updated the cluster to send email notifications after the job completes. Now we’ll tear down that infrastructure.

First, from the cluster, delete the SNS topic you created:

sns delete-topic --topic-arn ${MY_SNS_TOPIC}

Then from Cloud9, delete the cluster. This removes all the resources created for the cluster, including the filesystem, grafana dashboard, master node and compute nodes.

exit # exit to cloud9 instance
pcluster delete perflab-yourname

At any time you can re-create the cluster by running pcluster create perflab-yourname -c ~/environment/my-perf-cluster-config.ini as shown in the BUILD YOUR HPC CLUSTER section.
