HP-MPI Version 1.1 for Windows Release Note

HP-MPI V1.1 for Windows Release Note

Building and running applications

/out:hello_world.exe

"/libpath:C:\Program Files (x86)\Hewlett-Packard\HP-MPI\lib"

/subsystem:console

libhpmpi64.lib

libmpio64.lib

hello_world.obj

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:

> job add 4288 /numprocessors:1 ^

/stdout:\\node\path\to\a\shared\file.out ^

/stderr:\\node\path\to\a\shared\file.err "%MPI_ROOT%\bin\mpirun" ^

-ccp \\node\path\to\hello_world.exe

Step 6. Submit the job. The machine resources are allocated and the job is run.

> job submit /id:4288

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

configurations that require further control over the application layout or environment,

dynamically create an appfile within the job using the utility

"%MPI_ROOT%\bin\mpi_nodes.exe" as in the following example. Note that the environment

variable %CCP_NODES% cannot be used for this purpose because it only contains the single CPU

resource used for the task that executes the mpirun command. See “Running HP-MPI from

CCS” on page 21. To create the executable, perform Steps 1 through 3 from the previous

section. Then continue with:

Step 1. Create a new job.

> job new /numprocessors:16

Job queued, ID: 4288

Step 2. Submit a script. Verify MPI_ROOT is set in the environment (See the mpirun man

page for more information):
