To use an E-HPC cluster for high-performance computing, you may need to install specific software. This topic describes how to install and uninstall software.
Install software
You can install common software from the E-HPC console or manually install other software on the cluster.
Install from the console
-
Log on to the E-HPC console.
-
In the upper-left corner of the top navigation bar, select a region.
-
On the Cluster page, find the target cluster. In the Application Detail section, click Show next to Software Manage.
-
In the Software Manage panel, click the Installable Software tab.
-
Select the software that you want to install, and then click Install.
-
In the dialog box, click OK.
After the installation starts, you can monitor its status on the Software Installed tab in the Software Manage panel. The installation is complete when the status changes to Installed.
Install software manually
E-HPC clusters use Network-Attached Storage (NAS) to share data between compute nodes. You can manually install software in two ways:
-
Install the software in the
/optdirectory. This option makes the software available to all cluster users. -
Install the software in a user's home directory. This option typically makes the software available only to that specific user.
Some software requires a driver or a runtime environment to be installed on compute nodes, such as a GPU driver or a YUM package. After you install the software on a compute node, you can create a custom image from that node. You can then use this custom image to scale out nodes and automate the installation.
Uninstall software
You can use the console to uninstall software that was also installed from the console. For manually installed software, you must follow its specific uninstallation procedure.
-
On the Cluster page of the E-HPC console, find the target cluster. In the Application Detail section, click Show next to Software Manage.
-
In the Software Manage panel, click the Software Installed tab.
-
Select the software that you want to uninstall, and then click Detach.
-
In the dialog box, click OK.
