Omnibond: Creating an HPC Environment in Google Cloud with CloudyCluster
This lab was developed with our partner, Omnibond. Your personal information may be shared with Omnibond, the lab sponsor, if you have opted-in to receive product updates, announcements, and offers in your Account Profile.
In this lab, you create a complete turn-key High Performance Computing (HPC) environment in Google Cloud. This environment will provide the familiar look and feel of on-prem HPC systems but with the added elasticity and scalability of Google Cloud.
In this lab you see how CloudyCluster can easily create HPC/HTC jobs that will run on-prem or in CloudyCluster on Google Cloud. You can rely on the familiar look and feel of a standard HPC environment while embracing the capabilities and elasticity of Google Cloud. The HPC jobs can be easily configured to support many instance types including GPU, preemptible, and any number of memory & CPU configurations. You will always have the latest computational technology at your fingertips.
With CloudyCluster, users can now take advantage of the GUI developed by Open OnDemand. In this lab you will be able to experience many of the Open OnDemand HPC tools. Upload and download files with a file browser-like interface. Draft job scripts with the built-in web editor. Spin-up new computing instances and have them tear down automatically after your specified work window. The current release includes JupyterLab via JupyterHub and Cloudy desktop capabilities.
As part of Google Cloud and CloudyCluster you have a vast array of storage technologies available to you. In this lab you will take advantage of High Performance Parallel Storage for job execution.

The following labs will help provide the Google Cloud foundations for this lab:
Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
- Time to complete the lab---remember, once you start, you cannot pause a lab.
How to start your lab and sign in to the Google Cloud Console
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:
- The Open Google Console button
- Time remaining
- The temporary credentials that you must use for this lab
- Other information, if needed, to step through this lab
Click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account.
If necessary, copy the Username from the Lab Details panel and paste it into the Sign in dialog. Click Next.
Copy the Password from the Lab Details panel and paste it into the Welcome dialog. Click Next.
Important: You must use the credentials from the left panel. Do not use your Google Cloud Skills Boost credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.
Click through the subsequent pages:
- Accept the terms and conditions.
- Do not add recovery options or two-factor authentication (because this is a temporary account).
- Do not sign up for free trials.
After a few moments, the Cloud Console opens in this tab.
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
Click Activate Cloud Shell at the top of the Google Cloud console.
It takes a few moments to provision and connect to the environment. When you are connected, you are already authenticated, and the project is set to your PROJECT_ID. The output contains a line that declares the PROJECT_ID for this session:
gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.
(Optional) You can list the active account name with this command:
(Optional) You can list the project ID with this command:

CTRL + C to stop that command.
Click Check my progress to verify the objective.
After job submission the job will go through the following states:
- Pending state the job is waiting to be processed by CCQ
- CreatingCG state it is Creating the instances
- Provisioning state it is doing final node setup
- CCQueued state the job is in the process of being submitted to the scheduler
- Running state when it is handed off to the scheduler, which is SLURM in this job
- Completed state it has finished running successfully and the instances will tear down automatically
- Error state the job encountered an error during execution. The error will be logged in the Administration > Errors tab within the CloudyCluster UI
When operating in your own project, you can pause your HPC Environment if you do not have any more jobs to run. Once everything is paused, you can also stop the control node from the Google Cloud Console and restart it when you are ready to run jobs again.
Task 6. Deleting CloudyCluster
HPC Environment Deletion
- Delete or terminate any HPC Environments you have running by selecting the trash can icon in the upper right corner. This will delete the whole cluster.
- All data associated with this cluster will be removed, including any Cloud Storage or OrangeFS Storage. Make sure you back up any needed data to a different location.
Control instance deletion
In this lab you launched CloudyCluster and the Control Instance from the Google Cloud Marketplace. You then configured the Control Instance, set up an HPC environment and executed a job, set up, edited and launched sample HPC jobs, and deleted the CloudyCluster, HPC environment, and Control Instance.
