Examples of building on HP-UX and Linux

Change to a writable directory that is visible from all hosts on which the job will run.

Compile the hello_world executable file.

% $MPI_ROOT/bin/mpicc -o hello_world \
$MPI_ROOT/help/hello_world.c

This example uses shared libraries, which is recommended.

HP-MPI also includes archive libraries which can be used by specifying the appropriate compiler option.

	NOTE: HP-MPI uses the dynamic loader to interface with various interconnect libraries. Therefore, dynamic linking is required when building applications that will use HP-MPI.
