You use a Windows HPC Server 2008 cluster that has three dual-core nodes. You have a new Microsoft Message Passing Interface (MPI) job named Job1.exe that is designed to run as two processes on every node used.
You need to ensure that Job1.exe will run on all cores in the cluster.
Which command should you use?

You create a new application that uses a Windows HPC Server 2008 cluster. The company policy specifies the following limits:
Members of the ClusterUsers role can assign a maximum of 6 sockets to a job. Members of the ClusterDevelopers role can assign a maximum of 8 sockets. Members of the ClusterEngineers role can assign a maximum of 12 sockets. The default job template includes the Maximum Sockets parameter set to 6 and the Unit Types parameter set to include cores, sockets, and nodes. You are a member of the ClusterUsers and ClusterDevelopers roles. You submit a job to run the new application on 8 sockets. However, you receive an error. You discover that the credentials are valid and the permissions are set correctly. You need to ensure that the job can successfully be submitted to run on 8 sockets without compromising the company policy.
What should you do?

You develop an application for a Windows HPC Server 2008 cluster. You want to verify whether a customer s cl uter meets the configuration requirements of your application. The customer provides you remote access to the cluster. You need to retrieve information including the number of nodes, jobs, and tasks in various states on the cluster.
Which PowerShell cmdlet should you use?

You create a job that has two tasks named Task1.exe and Task2.exe. Task2.exe requires a minimum of two cores for optimum performance of your application. The corporate policy states that you must use a maximum of four cores to run a job. You need to write a Windows PowerShell script to use all the four cores to run the job every time the job is run.
Which script should you use?

You create an OpenMP application using Microsoft Visual C++. The application includes the following code segment. (Line numbers are included for reference only.)

01 omp_set_num_threads(10);
03 #pragma omp parallel
04 {
05 //Other code
06 #pragma omp barrier
07 int amount;
08 //Other code
09 amount++;
10 }

You set a breakpoint at line 09 and then start the debugger. You need to change the value for the variable amount to 15 only for the main thread.
