Prerequisites

Before your installation, please reference LiCO best recipe to make sure the cluster hardware use the correct drivers and settings. You can get the best recipe document from the below link:

https://support.lenovo.com/us/en/solutions/ht506408
Before your installation, please reference the Oses part of LeSI 18A_SI best recipe to install the OS security patch. You can get the best recipe document from the below link:

https://datacentersupport.lenovo.com/us/en/solutions/HT506335
You can setup CentOS/RedHat or SLES-12-SP3-Server/SLES-12-SP3-SDK base repository (online or local) on management node
Unless stated in this Guide, all commands are run on the management node
If you must open firewall. Please refer Cluster Service Summary to modify the firewall rules
The user is responsible for regularly updating the components and OS. It is important to regularly patch and update components and OS to prevent security vulnerabilities. For how to update OS packages, please refer to How to update OS packages
This document is for the typical cluster which contains management, login and compute nodes, as shown in the diagram below. But LiCO also support the cluster only contains management and compute nodes. For this kind of cluster, all the LiCO modules installed on login node need to be installed on management node.

Management node: It is the core of the HPC/AI cluster, undertaking primary functions such as cluster management, monitoring, scheduling, strategy management, and user and account management.
Compute node: As the name implies, the compute node completes computing tasks.
Login node: The login node connects the cluster to the external network or cluster. Users must use the login node to login to upload application data, to develop compilers and submit scheduled tasks.
Parallel File System: Provides a shared storage function. The high-speed network is always used to connect the cluster nodes and parallel file system. This Guide only show an example of installing NFS shared file system, how to setup the parallel file system is out of range.
Nodes BMC interface: BMC interface is used to access node’s BMC system
Nodes eth interface: Ethernet interface is used to manage the nodes in cluster, it also can be used to transfer computing data.
High speed network interface: The high speed network is optional. It is always used to support parallel file system, also can be used to transfer computing data.

Deploying Cluster Environment

If the cluster environment already exists, then you may skip this chapter. (check List of Components to see that software is already installed and can pass the Checkpoint A , Checkpoint B).

Installing LiCO

This chapter mainly introduces the distribution and installation of LiCO services in the cluster.
