• With the use of libmpirm.sl, the PA-RISC version of Load Sharing Facility (LSF)
can be run on the Itanium Processor Family (IPF) version of HP MPI.
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.
• Support for shared libraries. When a library is shared, programs using it contain
only references to library routines, as opposed to archive libraries, which must be
linked into every program using them. The same copy of the shared library is
referenced by each executable using it.
An advantage of shared libraries is that when the library is updated (e.g. to fix a
bug), all programs, which use the library immediately, enjoy the fix.
• Library names. Some of the libraries have been merged. Compilation wrappers have
been provided for convenience. Wrappers can also be used as templates.
• Multi-thread mode. By default, the non thread-compliant library (libmpi) is used
when running MPI jobs. Linking to the thread-compliant library (libmtmpi) is now
required only for applications that have multiple threads making MPI calls
