-AWS ParallelCluster is a framework that deploys and
-maintains high performance computing clusters on Amazon Web Services
-(AWS). Developed by AWS, AWS ParallelCluster facilitates both quick start proof
-of concepts (POCs) and production deployments. AWS ParallelCluster supports
-many different types of clustered applications and can easily be
-extended to support different frameworks. The CLI is stateless,
-everything is done using CloudFormation or resources within AWS.\
+AWS ParallelCluster is an AWS supported Open Source cluster management tool that makes it easy for you to deploy and
+manage High Performance Computing (HPC) clusters in the AWS cloud.
+Built on the Open Source CfnCluster project, AWS ParallelCluster enables you to quickly build an HPC compute environment in AWS.
+It automatically sets up the required compute resources and a shared filesystem and offers a variety of batch schedulers such as AWS Batch, SGE, Torque, and Slurm.
+AWS ParallelCluster facilitates both quick start proof of concepts (POCs) and production deployments.
+You can build higher level workflows, such as a Genomics portal that automates the entire DNA sequencing workflow, on top of AWS ParallelCluster.\
