You administer a Windows HPC Server 2008 cluster that has four compute nodes. Each compute node has two single-core processors. You have a Microsoft Message Passing Interface (MPI) executable file named myapp.exe. You have the following requirements: The MPI compute job must use all processes across all compute nodes. When the MPI compute job runs, no other job must process. You need to submit the myapp.exe file to the cluster by using the job command. Which command should you run on the head node?
A.
job submit mpiexec Cnp 8 myapp.exe
B.
job submit /numprocessors:8 myapp.exe
C.
job submit /exclusive:true mpiexec Cnp 8 myapp.exe
D.
job submit /numprocessors:8 /exclusive:true mpiexec myapp.exe
