Which function should you use?
You plan to develop a single program multiple data (SPMD) application by using Windows HPC Server 2008. You use multiple processes to perform intermediate calculations and to provide the results as a single number. You need to ensure that the intermediate results are collected and added together by using a single MPI function.

What should you do?
You are a system administrator for your company. You install a 64-bit version of Windows Server 2008 Standard Edition and a set of company standard applications on a new server. You install HPC Pack 2008 and configure a head node for a new Windows HPC Server 2008 cluster. You are unable to submit commands to the cluster from the command-line tools because of an authentication error. However, you are able to communicate with the cluster by using Windows PowerShell and the HPC Management Console. You need to resolve the authentication error. What should you do?
Which function should you use?
You plan to develop a parallel application by using Windows HPC Server 2008. You need to ensure that when the application starts, a parameter value is communicated to each process in the cluster by using a single call.
Which function should you use?
Which command should you run on the head node?
You administer a Windows HPC Server 2008 cluster that has four compute nodes. Each compute node is configured on the following three networks: Network A192.168.15.0/255.255.255.0Network B10.2.0.1/255.255.255.0Network C10.4.0.0/255.255.255.0 You need to ensure that Microsoft Message Passing Interface (MPI) uses Network C. Which command should you run on the head node?
Which type of communication should you use?
You plan to develop a parallel application by using Windows HPC Server 2008. The application performs the following tasks: Performs multistep calculations Processes data by using the same code segment that runs on each compute node You need to ensure that each compute process executes the same step simultaneously.
Which type of communication should you use?
What should you do?
You are a system administrator for your company. Your company deploys Windows HPC Server 2008 that has compute nodes on a private network and an application network. You install an InfiniBand subnet manager service and a DHCP service on the cluster head node. The InfiniBand host channel adapter (HCA) cards on the cluster nodes must use the IP addresses assigned by the DHCP service. You need to configure the DHCP service to support the outlined network configuration. What should you do?
Which function should you use?
You plan to develop a parallel application by using Windows HPC Server 2008. You need to implement a method that will send different data to each process in a communicator by using a single call.

Which configuration should you choose?
You are a system administrator for your company. You are configuring a new Windows HPC Server 2008 cluster. The cluster must have the following configuration: Two Windows Communication Foundation (WCF) broker nodesFifty compute nodesThe Windows Deployment Services role installed automatically on the head node You need to configure the nodes to meet the requirements of the cluster. Which configuration should you choose?
Which function should you use?
You plan to develop a parallel application by using Windows HPC Server 2008. You plan to use a method to control the calculations performed by each individual process. You need to ensure that different commands can be sent to each process.
Which function should you use?
What should you do?
You are a system administrator for your company. Your company network includes a DHCP server. You install a new Windows HPC Server 2008 cluster that has compute nodes isolated on a private network. The cluster compute nodes are configured for automatic IP address assignment. You also create a new DHCP scope for the private network on the DHCP server. You need to configure the cluster to support automatic IP address assignment for the compute nodes from the new DHCP scope. What should you do?
