--- title : "b. Create an HPC Cluster with EFA" date: 2020-05-12T10:00:58Z weight : 10 tags : ["configuration", "EFA", "ParallelCluster", "create"] --- In this step, you create an HPC cluster configuration that includes parameters for Elastic Fabric Adapter (EFA). {{% notice note %}} Follow the instructions in the [Create an HPC Cluster](/05-create-cluster.html) lab before starting this section. We'll be using the cluster you created there. {{% /notice %}} When we setup the cluster we used the **hpc6a.48xlarge** instance which enables EFA automatically. The following two parameters are set: * **EFA** true * **Placement Group** true You'll see them setup on the **Queue** section of the create cluster. ![Cluster Wizard](/images/pcluster/pcmanager-4.png) No action needed in this step.
