Building and running multihost on Windows CCS
clusters
The following is an example of basic compilation and run steps to execute
hello_world.c on a cluster with 16-way parallelism. To build and run
hello_world.c on a CCS cluster:
Step 1. Change to a writable directory on a mapped drive. The mapped drive
should be to a shared folder for the cluster.
Step 2. Open a Visual Studio command window. (This example uses a 64-bit
version, so a Visual Studio x64 command window is opened.)
Step 3. Compile the hello_world executable file:
X:\Demo> "%MPI_ROOT%\bin\mpicc" -mpi64 ^
"%MPI_ROOT%\help\hello_world.c"

Step 4. Create a new job requesting the number of CPUs to use. Resources are
not yet allocated, but the job is given a JOBID number which is printed
to stdout:
> job new /numprocessors:16
Job queued, ID: 4288
Step 5. Add a single-CPU mpirun task to the newly created job. Note that
mpirun will create more tasks filling the rest of the resources with the
compute ranks, resulting in a total of 16 compute ranks for this example:
