Installation

Appendix B. POE Installation Verification Program

To enable you to test the installation of POE, an Installation Verification Program (IVP) is provided in /usr/lpp/ppe.poe/samples/ivp. The IVP tests to see if these conditions are true:

• A non-root user ID is properly authorized in /etc/hosts.equiv or .rhosts.

• There is access to a C compiler. (The C compiler must be installed.)

If the previous conditions are true, the IVP does the following:

• Ensures that:

  • The following MPI libraries are there or linked for IBM RS/6000 SP systems:

    /usr/lpp/ppe.poe/lib/ip/libmpci.a

    /usr/lpp/ppe.poe/lib/ip/libmpci_r.a

    /usr/lpp/ppe.poe/lib/us/libmpci.a

    /usr/lpp/ppe.poe/lib/us/libmpci_r.a

  • poe, pmdv2, mpcc, and mpcc_r are there and are executable.

  • mpcc and mpcc_r scripts are in the path.

  • The file /etc/services contains an entry for pmv2, the Partition Manager daemon.

  • The file /etc/inetd.conf contains an entry for pmv2, and the daemon it points to is executable.

• Creates a work directory in /tmp/ivp <pid> to compile and run sample programs.

  Note:

  pid is the process id.

• Compiles sample programs.

• Creates a host.list file with local host names listed twice.

• Runs sample programs using IP protocol to two tasks.

• Removes all files from /tmp as well as the temporary directory.

• Checks for the dbx bos.adt.debug fileset, for parallel debuggers.
