HP-MPI Version 1.1 for Windows Release Note

HP-MPI V1.1 for Windows Release Note

Building and running applications

Go to VS Project, select View, select Property Manager and expand the project. This will

display the different configurations and platforms set up for builds. Include the appropriate

property page (HPMPI.vsprops for 32-bit applications, HPMPI64.vsprops for 64-bit

applications) in the Configuration/Platform section.

Select this page by either double-clicking the page or by right-clicking on the page and

selecting Properties. Go to the User Macros section. Set MPI_ROOT to the desired location

(i.e. the installation location of HP-MPI). This should be set to the default installation

location:

%ProgramFiles (x86)%\Hewlett-Packard\HP-MPI

NOTE This is the default location on 64-bit machines. The location for 32-bit machines

is %ProgramFiles%\Hewlett-Packard\HP-MPI

The MPI application can now be built with HP-MPI.

The property page sets the following fields automatically, but can also be set manually if the

property page provided is not used:

• C/C++ — Additional Include Directories

Set to "%MPI_ROOT%\include\[32|64]"

• Linker — Additional Dependencies

Set to libhpmpi32.lib or libhpmpi64.lib depending on the application.

• Additional Library Directories

Set to "%MPI_ROOT%\lib"

Building and running on a Windows 2003/XP cluster using appfiles

The example teaches you the basic compilation and run steps to execute hello_world.c on a

cluster with 4-way parallelism. To build and run hello_world.c on a cluster using an appfile,

perform Steps 1 and 2 from “Building and running on a single host” on page 34.

NOTE Specify the bitness using -mpi64 or -mpi32 for mpicc to link in the correct

libraries. Verify you are in the correct 'bitness' compiler window. Using -mpi64

in a Visual Studio 32-bit command window will not work.

Step 1. Create a file "appfile" for running on nodes n01 and n02 as:
