Cluster creation fails if enable_intel_hpc_platform=true is in the configuration file
Starting in September 2021, cluster creation fails if enable_intel_hpc_platform=true is in the cluster configuration file due to the earlier versions of Intel HPC Platform were obsoleted/removed.
2.10.0 and earlier.
Cluster creation will fail with an error message:
> pcluster create -nr parallelcluster-mycluster
Beginning cluster creation for cluster: parallelcluster-mycluster
Creating stack named: parallelcluster-mycluster
Status: parallelcluster-mycluster - CREATE_FAILED
Cluster creation failed. Failed events:

The cfn-init.log in the Master node contains either of the following error messages
No package intel-hpc-platform-*-2018.0-1.el7 available.
Package intel-hpc-platform-hpc-cluster is obsoleted by intel-hpc-platform-2.0-hpc-cluster, trying to install intel-hpc-platform-2.0-hpc-cluster-2.0-1.el7.x86_64 instead
We strongly recommend you upgrading to the latest 2.11.x or 3.x ParallelCluster to create the new cluster.
Generally, we need to slightly upgrade the version of the Intel HPC platform and use a flag to force the installation of the obsoleted package.
A pre_install script could be used to achieve the goal:
#!/bin/bash
. "/etc/parallelcluster/cfnconfig"
case "${cfn_node_type}" in
MasterServer)
sed -i "s/yum -y install --downloadonly --downloaddir=\/opt\/intel\/rpms/yum -y install --downloadonly --setopt=obsoletes=0 --downloaddir=\/opt\/intel\/rpms/" /etc/chef/cookbooks/aws-parallelcluster/recipes/intel_install.rb
sed -i "s/2018.0-1.el7/2018.0-*.el7/" /etc/chef/cookbooks/aws-parallelcluster/attributes/default.rb

You can create a file containing the script above and upload the file (e.g. to AWS S3). Then use the URL of the file for pre_install parameter in the configuration file
To learn more about pre install script and post install script, see this guide.
