# This is an OSCAR-specific RPM specfile.  It exists for two reasons:
# 1. Installing an Open MPI-installation-agnostic modulefile that will
#    automatically pick which of multiple Open MPI installations to use
#    if a specific one is not asked for by the user.
# 2. Make the main Open MPI spec file cleaner (don't need any of this
#    switcher gorp).

# Values specified here are what are used if the user does not pass in
# any defaults.

# Defining these to nothing overrides the stupid automatic RH9

%description

This RPM is used to install a Open MPI-installation-agnostic
modulefile that is used to automatically select which Open MPI
installation to use on a per-shell basis.  That is, if there are
multiple Open MPI installations on a single node (due to limitations
in the OSCAR design, aimed at difficulties in knowing exactly which
version of various support libraries to compile Open MPI against), it
will attempt to pick the "right" one and load the appropriate
modulefile for that installation.

Current possibilities include:
- plain vanilla Open MPI
- Open MPI with gm
- Open MPI with blcr
- Open MPI with blcr and gm

# Remove ourselves from the switcher repository.  Run the modules and
# switcher setup scripts because this RPM install may be part of the
# same shell that "rpm -ivh ..." the switcher/modules RPM's, in which
# case, the environment for those packages will not yet have been
# setup.  This is important to do *before* we are uninstalled because
# of the case where "rpm -Uvh openmpi-module..." is used; the current
# RPM will be uninstalled and then the new one will be installed.  If
# we are %postun here, then the new RPM will be installed, and then
# this will run, which will remove the [new] tag from switcher, which
# is obviously not what we want.

# Grrr...  It seems that "rpm -ivh a.rpm b.rpm c.rpm" is smart enough
# to re-order the order of installation to ensure that dependencies
# are met.  However, "rpm -e a b c" does *not* order the
# uninstallations to ensure that dependencies are still met.  So if
# someone does "rpm -e switcher modules openmpi-module", it is quite
# possible that rpm will uninstall switcher and/or modules *before*
# this RPM is uninstalled.  As such, the following lines will fail,
# which will cause all kinds of Badness.  Arrggh!!  So we have to test
# to ensure that these files are still here before we try to use them.

# If this is an upgrade, then we only want to do this when the last
# RPM is removed (i.e., when this is *not* an upgrade).

if test "$1" == 0; then

	# If this RPM was the system default switcher module, then
	# both print a warning and remove the system default.

		echo "WARNING: This RPM was the default MPI implementation!"
		echo "WARNING: There is no NO DEFAULT MPI implementation!"

* Sun Jul 02 2006 Jeff Squyres <jsquyres@cisco.com>
- Just use the prefix in the % files list so that we a) grab the whole
  tree and b) it removes all the directories when the RPM is removed.
  Thanks to Bernard Li for reporting the problem.

* Wed Apr 26 2006 Jeff Squyres <jsquyres@cisco.com>
- Adapted for Open MPI.  Still the way to go, despite claims to the
  contrary in the original log statement. :-)

* Wed Dec 31 2003 Jeff Squyres <jsquyres@lam-mpi.org>
- First version.  Hopefully, this RPM won't need to live very long
  because LAM/MPI 7.1 will obviate the need for it.
