       3.  _M_P_T__I_n_s_t_a_l_l_a_t_i_o_n__f_o_r__L_i_n_u_x__S_y_s_t_e_m_s

       This chapter describes requirements and procedures for MPT
       installation on Linux systems.


       3.1  _D_i_s_k__S_p_a_c_e__R_e_q_u_i_r_e_m_e_n_t_s

       Disk space requirements for the MPT for Linux product are
       approximately 6.3 Mbytes.


       3.2  _P_r_e_r_e_q_u_i_s_i_t_e_s

       This Linux beta release has been tested on the Red Hat 7.1
       distribution running the 2.4.9-3SGI_XFS_1.0.1smp kernel on
       IA64 Silicon Graphics 750 systems and on the Red Hat 7.1
       distribution running various implementations of the 2.4.17
       kernel on multiprocessor SN Itanium prototype systems.


       3.3  _I_n_s_t_a_l_l_i_n_g__t_h_e__M_P_T__R_P_M


       MPT is supplied as an RPM file.  The file's name contains
       the following information:

           Product (sgi-mpt)
           Version (1.6)
           Release (0)
           Architecture (ia64)

       For example, the name of the MPT RPM for the MPT 1.6 release
       is ssssggggiiii----mmmmpppptttt----1111....6666----1111....iiiiaaaa66664444....rrrrppppmmmm.  To install this RPM, log in as
       root and issue the following command:

       %%%% rrrrppppmmmm ----iiii ssssggggiiii----mmmmpppptttt----1111....6666----1111....iiiiaaaa66664444....rrrrppppmmmm

       3.3.1  _U_n_i_n_s_t_a_l_l_i_n_g__C_o_n_f_l_i_c_t_i_n_g__P_a_c_k_a_g_e_s
       When an MPI installation fails because pre-existing files
       are conflicting with the package you are installing, you can
       use the rrrrppppmmmm ----eeee command to uninstall the unwanted package.
       For example, if MPICH is running on your system and you want
       to uninstall it, use the following command:

           %%%% rrrrppppmmmm ----eeee mmmmppppiiiicccchhhh

       For more information about handling MPI and MPICH
       collisions, see "MPI and MPICH Collisions," later in this
       chapter.

       3.3.2  _D_e_p_e_n_d_e_n_c_y__C_h_e_c_k_i_n_g
       The MPT RPM performs thorough and precise dependency
       checking to ensure that all products necessary to support
       MPT are already on the system.  Many times, the dependency
       checking can be safely overridden. If you need to override
       the dependency checking, you can use the following command:

           %%%% rrrrppppmmmm --------nnnnooooddddeeeeppppssss ----iiii ssssggggiiii----mmmmpppptttt----1111....6666----1111....iiiiaaaa66664444....rrrrppppmmmm

       If earlier versions of MPT or certain other MPI
       implementations exist on the system, you can use the --------ffffoooorrrrcccceeee
       option to force the installation of the MPT RPM, as in the
       following example:

           %%%% rrrrppppmmmm --------ffffoooorrrrcccceeee ----iiii ssssggggiiii----mmmmpppptttt----1111....6666----1111....iiiiaaaa66664444....rrrrppppmmmm

       For example, the default installation of SGI MPT creates the
       following files:

               ////uuuussssrrrr////bbbbiiiinnnn////mmmmppppiiiirrrruuuunnnn
               ////uuuussssrrrr////llllooooccccaaaallll////bbbbiiiinnnn////mmmmppppiiii____llllaaaauuuunnnncccchhhh

               ////uuuussssrrrr////lllliiiibbbb////lllliiiibbbbxxxxmmmmppppiiii....aaaa

       If any of these files already exist on the system, RPM will
       not install the MPT package unless you use the --------ffffoooorrrrcccceeee
       option.


       3.4  _I_n_s_t_a_l_l_i_n_g__M_P_T__S_o_f_t_w_a_r_e__i_n__a__N_o_n_d_e_f_a_u_l_t__L_o_c_a_t_i_o_n

       RPM provides a means for creating, installing, and managing
       relocatable packages. That is, the MPT RPM can be installed
       in either a default or nondefault location.

       The default location for installing the MPT RPM is ////uuuussssrrrr.  To
       install the MPT RPM in a nondefault location, use the
       --------pppprrrreeeeffffiiiixxxx option, as shown in the following example. The











                                  - 3 -



       --------pppprrrreeeeffffiiiixxxx option specifies the alternate root directory for
       the installation of the MPT software (in this case, ////ttttmmmmpppp).

       After installation, you can use the RPM query facility,
       rrrrppppmmmm ----qqqqiiii, to display information about the MPT RPM.

       Another useful querying capability provided by RPM is
       rrrrppppmmmm ----qqqqllll, which displays the files associated with the

       Important note:  If the MPT software is installed in an
       alternate location, to compile, load, or run MPI programs,











                                  - 4 -



       you must specify the following environment variables:

          +o LLLLDDDD____LLLLIIIIBBBBRRRRAAAARRRRYYYY____PPPPAAAATTTTHHHH - Specifies the search location of

       Using a cpio file for installation provides a method of
       mimicking relocatable software. This method fits nicely into
       the 'modules' scheme with which most IRIX users are
       familiar. The following command takes an MPT RPM and creates
       from it a cpio file that contains the actual files that
       would have been installed if the RPM had been installed in
       the default manner.

           %%%% rrrrppppmmmm2222ccccppppiiiioooo ssssggggiiii----mmmmpppptttt----1111....6666----1111....iiiiaaaa66664444....rrrrppppmmmm >>>> ////ttttmmmmpppp////ssssggggiiii----mmmmpppptttt....ccccppppiiiioooo

       Once you have created the ....ccccppppiiiioooo file, you are free to
       install the software beneath any directory in which you have
       write permission.  That is, you do not necessarily need root
       permission and, as a consequence, you can install several
       versions of MPT on the same system to run concurrently for
       testing or development purposes. The following example
       demonstrates the process.

       As stated previously, if the MPT software is installed in an
       alternate location, to compile, load, or run MPI programs,
       you must specify the LLLLDDDD____LLLLIIIIBBBBRRRRAAAARRRRYYYY____PPPPAAAATTTTHHHH and MMMMPPPPIIII____LLLLAAAAUUUUNNNNCCCCHHHH
       environment variables.

       NOTE: The only apparent disadvantage of using ....ccccppppiiiioooo files to
       install the contents of an RPM package is that the system's
       RPM database does not reflect the installation of the files
       from the ....ccccppppiiiioooo file.


       3.7  _M_P_I__a_n_d__M_P_I_C_H__C_o_l_l_i_s_i_o_n_s

       The default installations of the MPT and MPICH RPMs cannot
       co-exist on the same Linux system.  This limitation exists
       because MPT and MPICH contain a number of files with
       identical names and absolute paths.  For example, both the
       MPT and MPICH distributions include a file named
       ////uuuussssrrrr////bbbbiiiinnnn////mmmmppppiiiirrrruuuunnnn.

       However, for systems already running MPICH, it is sometimes
       desirable to have MPT and MPICH co-existing on the same
       system for purposes of comparison.  To allow the two
       distributions to co-exist on the same system, you can
       install the MPT RPM in a nondefault location as described
       previously in "Installing MPT Files in a Nondefault
       Location." You will then want to be sure to refer to "Using











                                  - 6 -



       Dynamic Shared Libraries to Run MPI Jobs," later in this
       chapter.

       As an alternate remedy to MPT and MPICH collisions, you can
       choose between the two distributions by erasing one and
       installing the other, as appropriate.

       For example, to erase a version of MPICH that has been
       previously installed using RPM, enter the following command:

           %%%% rrrrppppmmmm ----eeee mmmmppppiiiicccchhhh

       Then you can install the MPT RPM as described previously.

       To re-install the MPICH RPM, you must find the MPICH RPM and
       install it just as you would install the MPT RPM.


       3.8  _U_s_i_n_g__D_y_n_a_m_i_c__S_h_a_r_e_d__L_i_b_r_a_r_i_e_s__t_o__R_u_n__M_P_I__J_o_b_s

       After you have installed the MPT RPM as default, use the
       following command to build an MPI-based application that
       uses the ....ssssoooo files:

       For C programs:

       %%%% ggggcccccccc ssssiiiimmmmpppplllleeee1111____mmmmppppiiii....cccc ----llllmmmmppppiiii
       %%%% mmmmppppiiiirrrruuuunnnn ----nnnnpppp 2222 aaaa....oooouuuutttt

       %%%% mmmmppppiiiirrrruuuunnnn ----nnnnpppp 2222 aaaa....oooouuuutttt

       The default locations for the include and ....ssssoooo files and the
       mmmmppppiiii____llllaaaauuuunnnncccchhhh and mmmmppppiiiirrrruuuunnnn commands are pulled in automatically.

       Assuming that the MPT package has been installed in a
       nondefault location (under the ////ttttmmmmpppp directory), as described
       earlier in "Installing MPT Files in a Nondefault Location,"
       the commands to compile, load, and check are as follows:

       If you are going to use a nondefault location for the ....ssssoooo
       files, it is important to set the LLLLDDDD____LLLLIIIIBBBBRRRRAAAARRRRYYYY____PPPPAAAATTTTHHHH
       environment variable, as in the following example:

           %%%% sssseeeetttteeeennnnvvvv LLLLDDDD____LLLLIIIIBBBBRRRRAAAARRRRYYYY____PPPPAAAATTTTHHHH ////ttttmmmmpppp////uuuussssrrrr////lllliiiibbbb
           %%%% lllldddddddd aaaa....oooouuuutttt

               lllliiiibbbbcccc....ssssoooo....6666 ====>>>> ////lllliiiibbbb////lllliiiibbbbcccc....ssssoooo....6666 ((((0000xxxx444400002222aaaacccc000000000000))))
               lllliiiibbbbddddllll....ssssoooo....2222 ====>>>> ////lllliiiibbbb////lllliiiibbbbddddllll....ssssoooo....2222 ((((0000xxxx4444000033339999aaaa000000000000))))

       Setting the MMMMPPPPIIII____LLLLAAAAUUUUNNNNCCCCHHHH environment variable allows you to
       direct mmmmppppiiiirrrruuuunnnn to invoke a nondefault version of mmmmppppiiii____llllaaaauuuunnnncccchhhh,
       as in the following example:

           %%%% sssseeeetttteeeennnnvvvv MMMMPPPPIIII____LLLLAAAAUUUUNNNNCCCCHHHH ////ttttmmmmpppp////uuuussssrrrr////llllooooccccaaaallll////bbbbiiiinnnn////mmmmppppiiii____llllaaaauuuunnnncccchhhh
           %%%% ////ttttmmmmpppp////uuuussssrrrr////bbbbiiiinnnn////mmmmppppiiiirrrruuuunnnn ----nnnnpppp 2222 aaaa....oooouuuutttt

       For MPI jobs to run correctly in a cluster environment in
       which MPT has been installed in a nondefault location, you
       must copy all of the pertinent pieces of MPT to an NFS-
       mounted filesystem.  This is the only way in which all of
       the nodes in the cluster can access the software.  The
       following method is one way to accomplish this (assuming
       ////ddddaaaattttaaaa////nnnnffffssss is an NFS-mounted directory and MPT has been
       installed in the nondefault location ////ttttmmmmpppp////uuuussssrrrr):

       This section provides a quick overview of some uses of RPM
       commands. Note that in the examples shown, the 1.6 version
       of the MPT RPM is used for illustrative purposes only.  The
       commands and instructions used in the examples are generic
       enough to apply to any Linux system and any installed RPM.
