Building and running MPMD applications on

Windows CCS

To run Multiple-Program Multiple-Data (MPMD) applications or other

more complex configurations that require further control over the

application layout or environment, use an appfile to submit the HP-MPI

job through the CCS scheduler.

Create the appfile indicating the node for the ranks using the -h <node>

flag, and the rank count for the given node using the -n X flag. Ranks

will be laid out in the order they appear in the appfile. Submit the job

using mpirun -ccp -f <appfile>. For this example, the

hello_world.c program will be copied to simulate a server and client

program in an MPMD application. The print statement for each will be

modified to indicate server or client program so the MPMD

application can be demonstrated:

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. Copy the hello_world.c source to server.c and client.c. Then edit

each file to change the print statement and include 'server' and 'client' in

each:

X:\Demo> copy "%MPI_ROOT\help\hello_world.c" .\server.c

Now, edit each to modify the print statement for both .c files to include

'server' or 'client' in the print so the executable being run is visible.

Step 4. Compile the server.c and client.c programs:
