HP XC System 2.x Software - Manual (Page 123)

Run the resulting prog.x under MPICH. However, various problems will be encountered.
First, the MPICH installation will need to be built to include shared libraries and a soft link
would need to be created for
libmpich.so , since their libraries might be named differently.
Next an appropriate LD_LIBRARY_PATH setting must be added manually since MPICH
expects the library path to be hard coded into the executable at link time by -rpath .
Finally, while the resulting executable would run over any supported system interconnect under
HP-MPI, it would not do this under MPICH due to not being linked against
libgm/libelan .
Similar problems would be encountered if linking under MPICH and running under HP-MPI’s
MPICH compatibility. MPICH’s use of
-rpath to hard code the library path at link time
would keep the executable from being able to find the HP-MPI MPICH compatibility library by
means of the LD_LIBRARY_PATH setting.
8.11 HP-MPI Documentation and Manpages
The HP MPI User’s Guide and HP-MPI Release Notices are available online in the following
locations:
• In /opt/hpmpi/doc after you install the product
• At http://docs.hp.com
• At http://www.hp.com/go/mpi
On systems that have the Version 7 Intel compiler, documentation is installed by default
with the compiler at
/opt/intel/compiler70/docs . On systems that have the
Version 8 Intel compiler, documentation is installed at /opt/intel_cc_80/docs or
/opt/intel_fc_80/docs .
The HP-MPI manpages are located in the MPI_ROOT/share/man/man1* subdirectory, and
can be grouped into three categories: general, compilation, and run-time. There is one general
manpage,
MPI.1 , that is an overview describing general features of HP-MPI. The compilation
and run-time manpages are those that describe HP-MPI utilities.
Table 8-2 describes the three categories of manpages in the man1* subdirectory that comprise
manpages for HP-MPI utilities.
