Installing Lustre
This InfiniPath release supports Lustre. Lustre is a fast, scalable Linux cluster file
system that interoperates with InfiniBand. To use Lustre, you need:
A Linux kernel that is one of the supported kernels for this release, patched
with Lustre-specific patches
Lustre modules compiled for the above kernel
Lustre utilities required for configuration
The InfiniPath Release Notes provide information about the Lustre patches. For
general instructions on downloading, installing, and using Lustre, go to:

Installing QLogic MPI in an Alternate Location
QLogic MPI can be installed in an alternate installation location by using the
--prefix option with rpm. This option is useful for installations that support
multiple concurrent MPIs, for other site-specific requirements, or for smooth
integration of QLogic MPI with mpi-selector.
The mpi-selector utility and QLogic MPI mpi-selector registration are
provided by RPMs in the OtherMPIs directory.
When this option is used, the argument passed to --prefix replaces the default
/usr prefix: QLogic MPI binaries, documentation, and libraries are installed under
that prefix. However, a few configuration files are installed in /etc regardless of
the desired --prefix.
Additionally, installations that are maintained in alternate locations must ensure
that the environment variable $MPICH_ROOT is always set to the same prefix that
was used to install the RPMs with the --prefix option. When set, the
$MPICH_ROOT variable allows QLogic MPI to correctly locate header and library
files for MPI compilation and running parallel jobs.
NOTE:
In InfiniPath 2.2, $MPICH_ROOT replaces the environment variable
$INFINIPATH_ROOT, which is now deprecated. In InfiniPath 2.1,
$INFINIPATH_ROOT assumed an RPM install --prefix of
$INFINIPATH_ROOT/usr.
