1.2.7.1 System Check
The HP-MPI V2.3 for Linux library includes a lightweight system check API which
does not require a separate license to use. This functionality allows customers to test
the basic installation and setup of HP-MPI without the prerequisite of a license.
The $MPI_ROOT/help/system_check.c file contains an example of how this API
can be used. This test can be built and run as follows:
% $MPI_ROOT/bin/mpicc -o system_check.x
$MPI_ROOT/help/system_check.c
% $MPI_ROOT/bin/mpirun ... system_check.x [ppr_message_size]
Any valid options can be listed on the mpirun command line.
During the system check, the following tests are run:
• hello_world
• ping_pong_ring
