Running the Client
Task 1 – Verifying Cluster State
In this task, you will verify that the nodes in your cluster are online.
- Open the HPC 2008 R2 Cluster Manager application from Start | All Programs | Microsoft HPC Pack 2008 R2 | HPC Cluster Manager.
In the Cluster Manager application, enter the Node Management section and verify that the Windows Azure nodes in the cluster are online, as shown in Figure 3:

Enter the Configuration section, select the Services option from the configuration list, and run the SOA Service Loading Diagnostics test on the AsianOptionsService service, as shown in Figure 4:

Running Service Load Diagnostics
- In the Run Diagnostic Tests window, select the AzureWorkerNodes node group from the Nodes in this group drop-down list, check the Go to Test Results to see test progress and results checkbox, and then click Run.
- In the Diagnostics window, wait for the test to complete and verify its success.
Note: If the service diagnostic fails, view the diagnostic information and perform the required fix. If this involves changing the service configuration or recompiling the service assemblies, you will need to redeploy your service before running the diagnostics again.
Task 2 – Running the Client Application
In this task, you will test the WCF service in the HPC cluster by running the client application.
- Open Microsoft Visual Studio 2010 from Start | All Programs | Microsoft Visual Studio 2010 | Microsoft Visual Studio 2010.
- Open the AsianOptions.sln solution file located in the AsianOptions\Source folder.
Build the solution and run the AsianOptions project. You should see the following Excel worksheet:
