Base Config

Configure AWS ParallelCluster

To guide our configuration, we’ll use the pcluster configure command.

pcluster configure

You can go with the default selections until you reach Automate VPC creation. Please read before you hit enter. :)

AWS Region

Please use the default which represents the region you are currently in.

SSH Key

We use the default value - will be overwritten anyways.

Scheduler

We use the default value SLURM.

Base OS

We use the default value alinux2 (AmazonLinux 2).

Instance Scaling

Just hit enter, we are going to overwrite the values later.

Instance Types

Just hit enter, we are going to overwrite the values later.

VPC

Focus! That is the important bit to have the VPC setup for us.

We are going to create new subnets for our cluster. Please type y and hit enter. The subsequent question will be the default (public subnet for headnode - private for compute).

Config Done

After the creation of the VPC, we reached the end of the config.
