E4S Pro Getting Started with Adaptive On-Demand Data Center (ODDC)¶
General Background Information¶
In this tutorial we will show you how to launch an HPC cluster on ODDC using the ODDC web interface.
This tutorial assumes you have access to a functioning ODDC server, installed and configured as described in the ODDC Documentation.
Tutorial¶
Log In¶
Enter the URL for your ODDC web portal instance in a web browser and log in with the credentials you created during configuration.
Create/Launch Cluster¶
Mouse over the menu on the left and select Cluster Manager.
You can create or import a new cluster using the '+' button in the upper right. Once your cluster is configured hit the ellipsis '...' on the right side of your cluster entry and select the deploy option. The portal will display the progress of the cluster initialization and let you know when the cluster is available.
Launch Jobs¶
Once your cluster has been launched you can create and issue jobs from the Job Manager, available via the menu on the right.
SSH To Cluster¶
To log into the cluster you can find the cluster's public IP address at the end of the startup log, available from the cluster's ellipsis menu while the cluster is active.
Alternatively you can ssh to the ODDC server and use the ODDC CLI to log in. To do this you must first configure a VPN to access the ODDC server. We recommend WireGuard. Once WireGuard is installed and configured with your authentication credentials and the address of the ODDC server you can ssh to the server. From the ODDC server you can log in to your cluster like oddc cluster:ssh <cluster-name> Add the --admin flag for access to sudo privileges on the cluster.
Cleanup¶
When you are finished de-allocate the cluster by entering its ellipsis menu and selecting destroy. The portal will show the destruction's progress and indicate when it is complete. Once the cluster has been deactivate it may be deleted entirely via the delete option in the ellipsis menu or kept in your cluster list for a new instance to be initialized later.
