The default location to install ParaStation MPI is
      /opt/parastation. Underneath this directory,
      several subdirectories are created containing the actual ParaStation MPI
      installation:
    
bin
        
            contains all executables and scripts forming the ParaStation MPI system.
            This directory could be included into the
            PATH environment variable for easy access to the ParaStation MPI
            administration tools.
          
config
        contains the example configuration
            file parastation.conf.tmpl.
          
Depending on the communication part of the ParaStation MPI system installed, more scripts and configuration files may be found within this directory.
doc
        contains the ParaStation MPI documentation after installing the corresponding RPM file. The necessary steps are described in the section called “Installing the documentation”.
include
        contains the header files needed in order to build ParaStation MPI applications. These files are primarily needed for building applications using the low level PSPort or PSE libraries.
These header files are not needed, if only MPI applications should be build or precompiled third party applications are used.
lib and lib64
        contains various libraries needed in order to build and/or run applications using ParaStation MPI and the ParaStation MPI libraries.
man
        contains the manual pages describing the ParaStation MPI daemons, utilities and configuration files after installing the documentation package. The necessary steps are described in the section called “Installing the documentation”.
In order to enable the users to access these pages using the man(1) command, please consult the corresponding documentation [1].
mpi2, mpi2-intel, mpi2-pgi
        
            contains an adapted version of MPIch2 after
            installing one of the various psmpi2 RPM
            files. 
            The necessary steps are described in the section called “Installing MPI”.
          
            Especially the sub-directories
            mpi2/bin,
            mpi2-intel/bin, etc, contain all
            the commands to run (mpiexec) and
            compile (mpicc,
            mpif90, ...) parallel tasks.
          
      All ParaStation specific kernel modules are
      located within the directory
      /lib/modules/.
    kernel release/kernel/drivers/net/ps4

                Usually this is either done by modifying the
                MANPATH environment variable or by editing
                the manpath(1) configuration file,
                which is /etc/manpath.config by
                default.
