Configuring WCF Broker Nodes

Applies To: Windows HPC Server 2008

Using the Service-Oriented Architecture (SOA) programming model, solution developers and architects can develop high-performance computing (HPC), cluster-enabled, interactive applications that enable distributed computing scenarios. To use an SOA application with your cluster, you must configure at least one node to be a Windows Communication Foundation (WCF) broker node. For more information about WCF broker nodes and SOA applications, see the Managing SOA Sessions in Windows HPC Server 2008 Step-by-Step Guide (

You can add the WCF broker node role to the head node, or you can change the role of a compute node to a WCF broker node. For more information, see Understanding Node Roles.


WCF Broker nodes must be connected to the enterprise network. For more information, see Network Configuration.

For information about using HPC Cluster Manager, see Overview of HPC Cluster Manager.

To configure a node as a WCF broker node

  1. In Node Management, in the Navigation Pane, click Nodes.

  2. In the views pane, right-click a node, then click Take Offline.

  3. In the Take Offline Node dialog box, click Yes. Look at the node status in the views pane, and wait until the state of the node has changed to Offline before going to the next step.

  4. In the views pane, right-click the node, then click Change Role.

  5. In the Change Node Role dialog box, select WCF broker node, and then click OK.

  6. In the views pane, right-click the node, and then click Bring Online.

  7. In the Navigation Pane, under Nodes, under By Group, click WCFBrokerNodes. Confirm that the node you configured appears in the list.

Additional considerations

  • To open HPC Cluster Manager, click Start, point to All Programs, click Microsoft HPC Pack, and then click HPC Cluster Manager. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
