HP-MPI Version 1.2 for Windows Release Note

(HPMPI.vsprops for 32-bit applications, HPMPI64.vsprops for 64-bit applications) in
Configuration→Platform.
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 (for example,
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"
1.8.5 Building and Running on a Windows Windows 2008 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” (page 25).
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 does not work.
1. Create a file "appfile" for running on nodes n01 and n02 as:
-h n01 -np 2 \\node01\share\path\to\hello_world.exe -h n02 -np 2
\\node01\share\path\to\hello_world.exe
2. For the first run of the hello_world executable, use -cache to cache your password:
> "%MPI_ROOT%\bin\mpirun" -cache -f appfile
Password for MPI runs:
When typing, the password is not echoed to the screen.
The HP-MPI Remote Launch service must be registered and started on the remote nodes.
mpirun will authenticated with the service and create processes using your encrypted
password to obtain network resources.
If you do not provide a password, the password is incorrect, or you use -nopass, remote
processes are created but do not have access to network shares. In the following example,
the hello_world.exe file cannot be read.
3. Analyze hello_world output.
HP-MPI prints the output from running the hello_world executable in non-deterministic
order. The following is an example of the output:
Hello world! I'm 1 of 4 on n01
Hello world! I'm 3 of 4 on n02
Hello world! I'm 0 of 4 on n01
Hello world! I'm 2 of 4 on n02
