Sample Cluster Configuration

To illustrate the concept of label-based scheduling, consider a cluster with two racks: RackA and RackB. The nodes in RackA are dedicated to the Production group, and the nodes in RackB are dedicated to the Development group. In addition, some nodes are configured with a fast CPU, one node is configured with high memory, and one node is configured with both a fast CPU and high memory. The following diagram illustrates the cluster configuration:
