1. Architecture of cluster deployed by AWS ParallelCluster + Several manual steps

2. Before installing AWS ParallelCluster

?A Linux environment is required.

?Current latest version of AWS ParallelCluster is 3.3.0

-We have tested Linux node on-premises with CentOS 7 and RHEL 8, and both of them can only get latest AWS ParallelCluster as version 3.1.4.

?We have installed AWS ParallelCluster on EC2 instance with Amazon Linux 2 as the operating system. In this environment the latest AWS ParallelCluster installed is 3.3.0.

-This guide is based on AWS ParallelCluster 3.3.0, therefore use Amazon Linux 2 to install AWS ParallelCluster is strongly recommended.

(1)Create EC2 instance for installing AWS ParallelCluster (Create VPC)

?Log in AWS Console --> Search VPC --> Create VPC

?Set Name tag auto-generation as "amazonlinux"

?Number of Availability Zones (AZs) set to 1. Number of private subnets set to 0. NAT gateways ($) set to None. VPC endpoints set to None. --> Press "Create VPC" button.

(2) Create EC2 instance for installing AWS ParallelCluster (Launch EC2 instance)

?Go to service -> EC2 and press "Launch instance"

?Name: amazonlinux

?OS: select Amazon Linux 2 AMI

?Instance type: select t2.micro

?Key pair:

?Press "Create new key pair"

?Key pair name: awsparallelcluster

?Key pair type: RSA

?Private key file format: .pem

?Press "Create key pair"

-Download awsparallelclsuter.pem

?Please confirm

?Key pair name

?Network settings

-Network: amazonlinux-vpc

-Subnet: amazonlinux-subnet-public1-??

-Press "Edit" and change auto-assign public IP from "Disable" to "Enable"

?Press "Launch instance"

(3) Create EC2 instance for installing AWS ParallelCluster (Connect to EC2 instance)

?At AWS Console --> EC2 instance --> Find the public IP of the EC2 instance (name: amazonlinux)

?Download and install PuTTY

?https://www.putty.org/

?Run "PuTTYgen"

?Load "awsparallelcluster.pem"

?Enter "key passphrase" and "confirm"

?Press "Save private key"

?Type filename as "awsparallelcluster.ppk"

?Run PuTTY -> Type Host name of EC2 instance (amazonlinux)

?Go to Connection->SSH->Auth -> Browse the ppk file created in last page

?Press "Open"

?Press "Accept"

?Login as: please enter "ec2-user"

?Enter passphrase for PPK key (awsparallelcluster.ppk)

Now you have created the Linux environment to install AWS ParallelCluster 3.3.0.
