When you use an Elastic High Performance Computing (E-HPC) cluster for high-performance computing, you can install software based on your business requirements. This topic describes how to install and uninstall software in the E-HPC console.
Prerequisites
The cluster is in the Running state.
Install software
You can directly install the common software provided by E-HPC in the E-HPC console, or manually install other software in an E-HPC cluster.
Install software in the E-HPC console
Go to the Cluster Details page.
Log on to the E-HPC console.
In the left part of the top navigation bar, select a region.
In the left-side navigation pane, click Cluster.
On the Cluster List page, find the cluster that you want to manage and click the cluster ID.
On the Cluster Details page, click the Software Application tab.
Click Add software.
In the dialog box that appears, select the software that you want to install and click OK.
On the Software Application tab, you can view the installation status. The Ready state indicates that the software is installed.
Manually install software
E-HPC clusters use Apsara File Storage NAS (NAS) to share data between compute nodes. Therefore, you can manually install business software by using one of the following methods.

When you install some software, you must also install drivers or specific runtime environments, such as GPU drivers and YUM packages, on each compute node. After you install software on a compute node, you can use the custom image that is created based on the compute node to add more compute nodes. This way, the software can be automatically installed on all compute nodes. For more information, see Create a custom image.
Uninstall software
You can perform the following operations to uninstall common software provided by E-HPC in the E-HPC console. For manually installed software, you can manually uninstall it based on the software conditions.
Go to the Cluster Details page.
Log on to the E-HPC console.
In the left part of the top navigation bar, select a region.
In the left-side navigation pane, click Cluster.
On the Cluster List page, find the cluster that you want to manage and click the cluster ID.
On the Cluster Details page, click the Software Application tab.
Find the software that you want to uninstall and click Delete in the Actions column.
In the message that appears, click OK.
Click the
