updated for
September 2001
New features of HP MPI version 1.7 include the following:
• New start up. The new HP MPI start-up requires that MPI be installed in the same
directory on every execution host. The default is the location from which mpirun is
executed. This can be overridden with the MPI_ROOT environment variable. We
recommend setting the MPI_ROOT environment variable prior to starting mpirun.
Previous versions of HP MPI allowed mpirun to exit prior to application termination
by specifying the -W option. The option -W used with mpirun is no longer supported.
To achieve similar functionality, place mpirun in the background.
