Introduction to LiCO

Lenovo Intelligent Computing Orchestration (LiCO) is an infrastructure management software for highperformance computing (HPC) and artificial intelligence (AI). It provides features like cluster management and monitoring, job scheduling and management, cluster user management, account management, and file system management.

With LiCO, users can centralize resource allocation in one supercomputing cluster and carry out HPC and AI jobs simultaneously. Users can perform operations by logging in to the management system interface with a browser, or by using command lines after logging in to a cluster login node with another Linux shell.

Typical cluster deployment

This Guide is based on the typical cluster deployment that contains management, login, and compute nodes.

Figure 1. Typical cluster deployment

Elements in the cluster are described in the table below.

Table 1. Description of elements in the typical cluster

Nodes eth interface

High speed network interface

Description

Core of the HPC/AI cluster, undertaking primary functions such as cluster management, monitoring, scheduling, strategy management, and user & account management.

Connects the cluster to the external network or cluster. Users must use the login node to log in and upload application data, develop compilers, and submit scheduled tasks.

Provides a shared storage function. It is connected to the cluster nodes through a highspeed network. Parallel file system setup is beyond the scope of this Guide. A simple NFS setup is used instead.

Used to access the node’s BMC system.

Used to manage nodes in cluster. It can also be used to transfer computing data.

Optional. Used to support the parallel file system. It can also be used to transfer computing data.

Note: LiCO also supports the cluster deployment that only contains the management and compute nodes. In this case, all LiCO modules installed on the login node need to be installed on the management node.

Prerequisites

• Refer to LiCO best recipe to ensure that the cluster hardware uses proper firmware levels, drivers, and settings:

• Refer to the OS part of LeSI 20B_SI best recipe to install the OS security patch:

support.lenovo.com/us/en/solutions/HT511104

• The installation described in this Guide is based on SLES 15 SP2.

• A SLE-15-SP2-Full-x86_64-GM-Media1.iso local repository should be added on management node.

• Unless otherwise stated in this Guide, all commands are executed on the management node.

• To enable the firewall, modify the firewall rules according to “Firewall settings” on page 51.

• It is important to regularly patch and update components and the OS to prevent security vulnerabilities. Additionally it is recommended that known updates at the time of installation be applied during or immediately after the OS deployment to the managed nodes and prior to the rest of the LiCO setup steps

• LiCO leverages OpenHPC packages which aggregate a number of common ingredients required to deploy and manage High Performance Computing (HPC) Linux clusters including provisioning tools, resource management, I/O clients, development tools, and a variety of scientific libraries. Lenovo provides a download of the most recent version of OpenHPC which is unmodified from what is distributed by OpenHPC. There are known open-source components within OpenHPC that have known, registered, vulnerabilities. None of these issues has been assessed as critical. However, it is recommended that the user update or remove such components using the native package management tools.

LiCO 6.1.0 Installation Guide (for SLES)

Set xCAT node information

Note: If the ThinkSystem SR635/SR655 server is used in other nodes, change “serialport=0” to “serialport=

1” before running the following commands.

Step 1. Run the following commands to import the compute node configuration in the lico_env.local file to

xCAT:

for ((i=0; i<$num_computes; i++)); do

mkdef -t node ${c_name[$i]} groups=compute,all arch=x86_64 netboot=xnba mgt=ipmi \

bmcusername=${bmc_username} bmcpassword=${bmc_password} ip=${c_ip[$i]} \

mac=${c_mac[$i]} bmc=${c_bmc[$i]} serialport=0 serialspeed=115200;

done

Step 2. Run the following commands to import the login node configuration in the lico_env.local file to

xCAT:

for ((i=0; i<$num_logins; i++)); do

mkdef -t node ${l_name[$i]} groups=login,all arch=x86_64 netboot=xnba mgt=ipmi \

bmcusername=${bmc_username} bmcpassword=${bmc_password} ip=${l_ip[$i]} \

mac=${l_mac[$i]} bmc=${l_bmc[$i]} serialport=0 serialspeed=115200;

done

Step 3. (Optional) If the BMC username and password of the node are inconsistent, run the following

command to make them consistent:

tabedit ipmi

Step 4. Run the following command to configure the root account password for the node:

chtab key=system passwd.username=root passwd.password=<ROOT_PASSWORD>

Add host resolution

Note: If the cluster already has the OS installed and can resolve the IP address through the hostname, skip

this section.

Run the following commands to add host resolution:

chdef -t site domain=${domain_name}

chdef -t site master=${sms_ip}

chdef -t site nameservers=${sms_ip}

sed -i "/^\s*${sms_ip}\s*.*$/d" /etc/hosts

sed -i "/\s*${sms_name}\s*/d" /etc/hosts

echo "${sms_ip} ${sms_name} ${sms_name}.${domain_name} " >> /etc/hosts

makehosts

Configure DHCP and DNS services

Note: If all nodes in the cluster have the OS installed, skip this step.

Chapter 2. Deploy the cluster environment 11

Run the following commands to configure DHCP and DNS services:

makenetworks

makedhcp -n

makedhcp -a

makedns -n

echo "search ${domain_name}" > /etc/resolv.conf

echo "nameserver ${sms_ip}" >> /etc/resolv.conf

Note: Please reference to the following two links to make sure that the management node is pointing at the same DNS as other nodes:

https://sourceforge.net/p/xcat/wiki/XCAT_iDataPlex_Cluster_Quick_Start/#install-xcat-on-the-management-node https://sourceforge.net/p/xcat/wiki/Cluster_Name_Resolution/

Install a node OS through the network

Note: If all nodes in the cluster have the OS installed, skip this section.

Run the following commands to set and install the necessary OS mirror:

nodeset all osimage=sle15.2-x86_64-install-compute

ln -s /install/sles15.2/x86_64/1 /install/sles15.2/x86_64/2

rsetboot all net -u

rpower all reset

Note: It takes several minutes to complete the OS installation. You can use the following command to check the progress:

nodestat all

Create local repository for other nodes

Run the following commands:

cat << eof > /var/tmp/SLES15-SP2-15.2.repo
