Installation

Steps Performed by the POE Installation Verification Program

The POE Installation Verification Program is located in the /usr/lpp/ppe.poe/samples/ivp directory, invoked by the ivp.script shell script. It checks for the needed files and libraries and makes sure that everything is in order. It also issues messages when it finds something wrong.

You need the following in order to run the ivp.script:

• A non-root userid properly authorized in /etc/hosts.equiv or the local .rhosts file.
• Access to a C compiler.

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

1. Ensures that:
   • MPI library /usr/lpp/ppe.poe/lib/ip/libmpci.a is there or linked for IBM RS/6000 SP systems.
   • MPI library /usr/lpp/ppe.poe/lib/ip/libmpci_r.a is there or linked for IBM RS/6000 SP systems.
   • MPI library /usr/lpp/ppe.poe/lib/us/libmpci.a is there or linked for IBM RS/6000 SP systems.
   • MPI library /usr/lpp/ppe.poe/lib/us/libmpci_r.a is there or linked for IBM RS/6000 SP systems.
   • poe, pmdv3, 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 pmv3, the Partition Manager daemon.
   • The file /etc/inetd.conf contains an entry for pmv3, and that the daemon it points to is executable.
2. Creates a working directory in /tmp/ivppid to compile and run sample programs.

   Note that pid is the process id.

   • Compiles sample programs.
   • Creates a host.list file with local host names listed twice.
   • Runs sample programs using Internet Protocol (IP) protocol to two tasks, using both threaded and non-threaded libraries.
   • Removes all files from /tmp, as well as the temporary directory.
   • Checks for the dbx bos.adt.debug fileset for pdbx.
